T2 hyperintense lesion

Differential diagnosis of T2 hyperintense spinal cord lesions: part B Hyperintense spinal cord signal on T2-weighted images is seen in a wide-ranging variety of spinal cord processes. Causes including simple MR artefacts, trauma, primary and secondary tumours, radiation myelitis and diastematomyelia were discussed in Part A T2-hyperintense foci on brain MR imaging MRI is a sensitive method of CNS focal lesions detection but is less specific as far as their differentiation is concerned. Particular features of the focal lesions on MR images (number, size, location, presence or lack of edema, reaction to contrast medium, evolution in time), as well as accompanyi

The radiologist or technician can view hyperintense lesions on T2 MRI images in real time from the observation room. In most cases hyperintense lesions are bright, glowing patches on MRI scans The vast majority of focal liver lesions are hyperintense on T2-weighted magnetic resonance (MR) images. Rarely, however, hepatic nodules may appear totally or partially hypointense on those images The majority of abnormal findings or lesions on T2-weighted fast spin-echo (FSE) magnetic resonance imaging (MRI) are hyperintense due to increased perfusion or fluid content, such as infections, tumours or synovitis. Hypointense lesions on T2-weighted images (both fat-suppressed and non-fat-suppres T2 hyperintense lesion of left lobe of thyroid gland. A 57-year-old female asked: what is a 2cm t2-hyperintense lesion in the right hepatic lobe an indication of? Dr. Masoud Sadighpour answered. Internal Medicine 38 years experience. Need attention: Very non-specific finding. It might be a siple cyst or a tumor a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Usually this is due to an increased water content of the tissue. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this u

Transverse Myelitis and Focal White Matter Lesions

Time to read: 5 minutes White matter hyperintensities (WMHs) are lesions in the brain that show up as areas of increased brightness when visualised by T2-weighted magnetic resonance imaging (MRI). WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients These lesions are more easily seen on T2 weighted images, which describes the frequency (speed) of the radio impulses used during your scan. White spots may be described in your MRI report as high signal intensity areas, white matter hyperintensities, leukoaraiosis (often used if spots are felt to be caused by decreased blood flow), or. Corpus callosum lesion (arrow) is easy to appreciate on the midsagittal image to the left. The same colossal lesion can also be spotted on an axial T2 to the right. Figure 8. Cortical, juxtacortical lesions, and U-fiber lesions T2 hyperintensities may occur in demyelinating diseases such as multiple sclerosis, vasculitis (inflammation of the arteries in the brain), lyme disease. It's important to note that any tissue with.. Brain lesions are a type of damage to any part of brain. Lesions can be due to disease, trauma or a birth defect. Sometimes lesions appear in a specific area of the brain. At other times, the lesions are present in a large part of the brain tissue. At first, brain lesions may not produce any symptoms

Visualization of hyperintense ovarian follicles or of a functional cyst at T2-weighted imaging helps identify the ovaries. The presence of a pedicle between the uterus and the lesion indicates that the lesion arises from the uterus t1 and t2 hyperintense lesion in left aspect of the t2 vertebral body, which loses signal on inversion recovery imaging felt to reflect a hemangioma. Dr. Paxton Daniel answered Radiology 39 years experience Sounds right: Fat containing benign vertebral body hemangiomas often look just like this Many soft tissue masses have an indeterminate appearance on MRI, often displaying varying degrees and extent of T2 hyperintensity. However, a subset of neoplasms and tumor-like lesions may exhibit prominent areas of T2 hypointensity relative to skeletal muscle. The hypointensity observed on T2-weigh

Differential diagnosis of T2 hyperintense spinal cord

Early lesions are poorly defined and isointense on T1-weighted images, heterogeneously T2 hyperintense, and have diffuse surrounding soft-tissue edema (39). As peripheral calcification develops, peripheral low SI may become visible on MR images (39) The lesions typically are hypointense on T1 and hyperintense on T2 compared to liver parenchyma. Classically, the lesions are hyperintense, almost light bulb bright on T2-weighted imaging. This feature helps distinguish them from malignant lesions, which are typically of intermediate signal on T2 imaging

T2-hyperintense foci on brain MR imagin

  1. T2-weighted sequences are an integral part of magnetic resonance (MR) imaging performed for the characterization of adnexal lesions. A relatively small number of these lesions demonstrate low signal intensity on T2-weighted MR images
  2. INTRODUCTION. T2 hyperintense breast lesions can have inflammatory, infectious, or neoplastic etiologies. The histopathologic background for T2 hyperintensity of these breast lesions can be cystic or microcystic components, adipose or sebaceous components, mucinous or loose myxoid stroma, edema, necrosis or hemorrhagic changes. [] The breast is made of three components: Glandular, adipose, and.
  3. T2/FLAIR lesions can directly account for some symptoms. For example, a brainstem lesion can cause room spinning sensations and balance problems. Cervical (neck) spinal cord T2/FLAIR lesions could cause tingling and numbness in the hands and legs. Many of the lesions may not be causing obvious symptoms

Using a T2* sequence, a central vein was identified in 45% of MS lesions at 3 T and 87% of MS lesions at 7 T, versus only 8% of nonspecific WMH s at 7 T in healthy volunteers (12). Lesions that are dark on T1-weighted images (black holes) correlate with severe histologic damage, higher degree of demyelination, and axonal loss (13) These lesions are usually mono-ostotic; however, polyostotic tumors or satellite lesions are rarely seen and can be difficult to differentiate from metastatic GCT. Periostitis is not present. There is low signal on T1 and variable T2 MRI signal, which may include hyperintense regions or fluid levels secondary to aneurysmal bone cysts This lesion was outside of the radiation treatment field for the more prominent lesion, and then progressed to include mass effect and contrast enhancement on post-contrast T1 (I). Case 3: (J) Coronal T2 shows hyperintense cortical thickening in the right temporal lobe

What are Hyperintense Lesions? (with pictures

White matter hyperintensities (WMH) lesions on T2 and fluid attenuated inversion recovery (FLAIR) brain MRI are very common findings in elderly cohorts and their prevalence increases from 15% at the age of 60 to 80% at the age of 80 [1-4].Mainly located in the periventricular white matter (WM) and perivascular spaces, they can also be detected in deep WM B, On the sagittal T2-weighted FSE image the two lesions remain hyperintense to the normal bone marrow. C, The two lesions are dark on the STIR image, blending in with normal bone marrow. D, Axial T2WI at the T12 level demonstrates the hyperintense well-circumscribed hemangioma within the left side of the vertebral body t1 and t2 hyperintense lesion in left aspect of the t2 vertebral body, which loses signal on inversion recovery imaging felt to reflect a hemangioma. Dr. Paxton Daniel answered. 39 years experience Radiology. Sounds right: Fat containing benign vertebral body hemangiomas often look just like this. 1 doctor agrees

T2 sequences are routinely being performed as part of standard breast MRI protocols, but there is not a well-established definition for a T2 hyperintense lesion . In our study, we defined a mass as being T2 hyperintense if it was as hyperintense as the axillary lymph nodes; however, several authors have defined T2 signal in comparison with. t1 and t2 hyperintense lesion in left aspect of the t2 vertebral body, which loses signal on inversion recovery imaging felt to reflect a hemangioma. Dr. Paxton Daniel answered. Radiology 39 years experience. Sounds right: Fat containing benign vertebral body hemangiomas often look just like this The hyperintense lesion could be due to a cyst or tumor. It could be a simple kidney cyst. Simple kidney cysts are more common as people age. An estimated 25 percent of people 40 years of age and 50 percent of people 50 years of age have simple kidney cysts. Hope this helped and do keep us posted. I was advised a T2 hyperintense structure on my. Paraphrasing W.B. Matthews about 'dizziness,' there can be few physicians so dedicated to their art that they do not experience a slight decline in spirits when they learn that a patient's brain MRI shows nonspecific white matter T2-hyperintense lesions compatible with microvascular disease, demyelination, migraine, or other causes. 1 The situation is particularly vexing if the patient. Hyperintense Kidney Lesion. My husband had a Lumbar Spine MRI. One of the findings noted by the Radiologist was There is dependent soft tissue edema seen in the lumbar region. No paraspinous mass is seen. There is a 3 cm T2 hyperintense lesion likely reflective of a cyst within the right kidney anteriorly

A 3 Tesla MRI catches about 30% more lesions than a 1.5 Tesla MRI. Neuro patients going in for head and cervical MRI should ask to see if they are being imaged on a 3.0 Tesla MRI using an MS imaging protocol. My 1.5 Tesla study was like flushing $1800 down the crapper. Now I have a new Neuro and they will do a 3 Tesla study in Nov Axial T2-weighted MR image demonstrates multiple bilateral, well-defined hyperintense lesions (arrows) along the pelvic sidewalls (more on the right side than on the left). Asymmetric hypertrophy and prominent venous varicosities are seen in the right gluteal musculature (arrowheads), features that are typical of Klippel-Trénaunay-Weber syndrome My doctor ordered an MRI and it said: Stable T2 hyperintense lesion in the right kidney. Is that a cause for concern? txcharm71 October 20, 2013 . A week ago, I was eating and started feeling bloated. It lasted through the week but I wasn't having any other symptoms, just fullness in belly and burping. It got worse through the week and I was. I had an MRI and the results say T1 & T2 Brainstem hyperintense without inhancement. 5 mm lesion in right Pons what does this mean please? 1 doctor answer • 1 doctor weighed in Mri spine done and it read 10 mm t2 hyperintense, t1 hypo intense lesion in the inferior aspect of spleen

MR imaging is superior in defining tumor characteristics and extension, particularly perineural spread. 29 It is especially useful when imaging is performed for suspected pleomorphic adenoma, because these lesions are typically hyperintense on the T2-weighted sequences and may be invisible on CT. 30 The drawbacks of MR imaging include the. B, At MRI, coronal HASTE shows lesion to be predominantly T2 dark. C , Axial T1 weighted imaging demonstrates hyperintense, layering posterior component. D , MRI subtraction images show anterior enhancing soft tissue and confirms nonenhancing, posteriorly layering hemorrhage (A) T2 hypointensity at right apex; (B) hyperintensity of same lesion on DCE, likely tumour. In some cases, BPH may be found in PZ tissue and resemble prostate cancer. Well-defined, rounded lesions with internal heterogeneity on T2 weighted MRI are suggestive of benign hyperplasia over cancer MS lesions appear as bright spots in a T2-weighted MRI scan. The appearance of more lesions on this type of scan may indicate higher levels of disability and a less favorable long-term outcome T2-weighted image shows expansile heterogeneously T2 hyperintense lesion (arrowhead) of left petrous apex that has encroached into clivus. Round T2 hyperintense lesion at left pons is due to partial volume artifact from large posterior fossa component of lesion (not shown). Also note congestion of left mastoid (arrow)

The hypointense liver lesion on T2-weighted MR images and

  1. If a T2-hyperintense mass has a thin rim of peripheral enhancement and no internal enhancement, it is a truly cystic (ie, fluid-filled) lesion. Ganglia are very common and should be considered whenever a periarticular mass with these characteristics is identified at MR imaging ( Fig 1 )
  2. The marked sensitivity of T2-weighted images (T2WI) allows white matter lesions to be readily detected, providing high sensitivity to lesion detection. However, the difficulty confronting the radiologist is that a wide gamut of diseases may involve the white matter, and thus white matter lesions are often nonspecific in nature, that is, low.
  3. The lesion is intermediate to high signal on T2 weighted images (b, c). There is an associated T2 hyperintense component, consistent with an aneurysmal bone cyst (white arrow), which can be seen in 10-20% cases of osteoblastoma
  4. ant findings on MRI that raised suspicion for a complex renal lesion in these cases were lesion nodularity (n = 8), low T2 signal intensity (n = 3), and lesion septations (n = 1). The mean axial diameter ± SD of all simple cysts was 2.2 ± 1.2 cm (range, 1-7.5 cm), and that of all complex renal lesions was 2.1 ± 1.2 cm (range, 1.1.
  5. BACKGROUND AND PURPOSE: Vertebral hemangiomas are benign vascular lesions that are almost always incidentally found in the spine. Their classic typical hyperintense appearance on T1- and T2-weighted MR images is diagnostic. Unfortunately, not all hemangiomas have the typical appearance, and they can mimic metastases on routine MR imaging. These are generally referred to as atypical hemangiomas.

Axial T2 (A) and postcontrast T1 (B) weighted images of the brain showing a large well defined cystic lesion with mural nodule which is mildly hyperintense on T2 weighted image (A) seen involving left cerebellar hemisphere and vermis with thick irregular intense enhancement of the wall of the cyst and the mural nodule T2 hyperintense lesions can alter in size over the course of weeks and a proportion of their volume disappears because of resolution of oedema, although complete resolution is rare. Lesions can also cause local atrophy, a finding best appreciated in the optic nerve or spinal cord. About 50% of acutely T1 hypointense lesions resolve and this may.

T2 black lesions on routine knee MRI: differential

Lesions with high lipid content are hyperintense on T1- and T2-WI, whereas the acrystalline form of cholesterol and the presence of keratin and microcalcifications may result in low signal on T2-WI. After administration of intravenous gadolinium contrast medium, there is a lack of contrast enhancement in non-complicated epidermoid cysts (Fig. A, Axial T2-weighted MR image shows 12-mm T2 hyperintense lesion (arrow) in pancreatic neck that had communication with pancreatic duct on MRCP images (not shown). No enhancing solid components or main ductal dilatation was seen. Yearly surveillance with MRI was prescribed

T2 hyperintense lesion of left lobe of thyroid gland

  1. hyperintense on T2 weighted images; signal abnormality is typically poorly marginated; plaque enhancement correlates with acute lesion activity (usually lasts less than two months) in most patients additional lesions of variable enhancement are present in the brain and spinal cord (MS is solely confined to the spinal cord in 5-24% of patients 4
  2. On MRI, they are typically hyperintense on T1 and T2-weighted images due to fat; the signal intensity varies on fat-saturated sequences depending on the amount of fat in the lesion relative to vascularity and interstitial edema; Enhancement patterns are variable, but a mild degree of heterogeneous enhancement is commo
  3. In case of lack of worrisome features for HCC (e.g., arterial phase hyperenhancement and washout on portal venous or delayed washout, fat content within lesion, hyperintensity on T2-weighted images or diffusion restriction) and the presence of hyperintensity on pre-contrast T1-weighted images, and if the lesion is less than 1 cm, the.

Meaning of T2 hyperintense signal on MRI - Neurology - MedHel

For the evaluation of lesions by MRI, T1- and T2-weighted images remain a basic requirement for lesion characterization 1-3. In general, owing to their high cellular water content, the majority of solid lesions in the female pelvis appear hyperintense on T2-weighted images A pseudocyst appears hyperintense on T2-weighted sequences and has homogeneous bright internal signal intensity, a characteristic feature that confirms that the lesion is a fluid-filled structure . On unenhanced T1-weighted MR images, the lesion is hypointense unless it contains hemorrhagic elements that are hyperintense T2: increased signal intensity, greater than other T2 hyperintense liver lesions (e.g. hemangioma) T1 C+: hepatic cysts do not enhance after administration of any type of contras PI-Rads v2 - Lesion Vikas Kundra, M.D., Ph.D. Lesions: Up to 4 findings category 3, 4, or 5 - give location - All involved sectors should be indicated - Lesion size Largest dimension on an axial image - Or largest dimension on any plane or sequence that best depicts largest dimension of the lesion - Prefer ADC for PZ and T2 for T

Proximal lesions may cause enlargement of the stylomastoid foramen. MRI shows a well-defined mass that is T1 isointense and T2 slightly hyperintense to muscle with enhancement on postgadolinium images (Figure 5). Larger lesions may have a characteristic intramural cyst. 8,10-11. Preoperative diagnosis of FNS is extremely difficult and uncommon Typically, the T1 signal intensity is lower than that of liver and the T2 signal is heterogenously hyperintense. They typically demonstrate only mild to moderate homogeneous (or mildy heterogeneous) enhancement after gadolinium. 50. Pediatric lesions: Neuroblastoma, ganglioneuroma, ganglioneuroblastoma Neuroblastoma Cold on Tc-99m sulfur colloid. Hepatocellular carcinoma - most common primary malignancy of liver, a/w cirrhosis. T1. Small Lesions (<1.5cm, aka dysplastic nodule) - hyperintense. Large Lesions - may be hypointense secondary lipid (can have drop out on out of phase imaging), copper or glycogen. T2 - hyper os isointense • T2-hyperintense circumscribed mass • Benign epithelial lesion composed of tightly packed tubular and acinar components with sparse associated intervening stroma. • Rare. • Can be asymptomatic or present as a palpable lump at breast exam. • Most commonly found in young women of reproductive age. • There is no associated risk o

The lesions are homogeneously hyperintense on the T2-weighted MR image. CT and MRI demonstrated progressive centripetal enhancement. On MR studies, splenic hemangiomas are isointense to hypointense on the T1-weighted images and typically hyperintense on the T2-weighted images compared with the normal spleen ( Fig. 105-5C ) On T2-weighted sequences, the signal from the necrotic ablation zone was heterogeneously hypointense (Fig. 9). The residual tumor tissue appeared as a peripheral portion that was hypointense on the T1-weighted images and hyperintense on the T2-weighted images. On DWI, twenty out of 24 treated lesions (83%) showed restricted diffusion T2-weighted sequences they are seen as lesions with a great hyperintensity (2) (Figure 10 and 11). The brightness observed in T2 is greater and more ho-mogeneous than the brightness of metastasis, which permits the differentiation (2). Without a doubt, the behavior of these lesions in dynamic phases after in White matter disease, or leukoaraiosis, involves the degeneration of the brain's white matter. White matter disease usually occurs due to aging, but it can also affect young people. Learn more here The anterior mass is isointense to subcutaneous fat and the posterior mass is hyperintense relative to the subcutaneous fat. B, On a T1-weighted image with fat saturation, the anterior mass loses signal secondary to the presence of macroscopic fat, whereas the posterior lesion remains hyperintense secondary to blood products

White Matter Hyperintensities on MRI - Artefact or

the brain. Meningiomas vary from hypointense to hyperintense on T2-weighed images. Approximately 50% are isointense, 40% hyperintense and 10% hypointense relative to the gray matter. They reveal a strongly and homogeneous contrast enhancement, being the most sensitive method for detecting meningiomas T1-weighted MRI images show a heterogenous hypointense lesion whereas T2-weighted images show a hyperintense lesion. The lesion shows good enhancement after contrast administration on T2-weighted images. Metastases to the Adrenal Gland. This is the second most common mass after adrenal adenoma, making up 50% of all adrenal masses Typical MS lesion in the cervical spinal cord. ( A ) Sagittal T2-weighted MR image showing hyperintense, dorsally located spinal cord lesion at the C2 level.( B ) On axial T2-weighted MR image, a hyperintense, wedge-shaped lesion is located in the dorsal aspect of the spinal cord lesion, occupying less than half the cross-sectional area of the cord These lesions are usually not as hyperintense on T2-weighted images as a glomus tumor. In addition, the presence of hemosiderin is frequently seen, manifested as foci of low signal intensity within the lesion, most pronounced on gradient echo pulse sequences Axial T1- (a) and T2-weighted images with fat suppression (b) show a complex cystic round lesion with a hypointense nodule (a, b, white arrow) on the right side arising from the right ovary. Observe ovarian parenchyma with small follicles (b, void arrows). A linear T1 hyperintense portion is located on the upper part of the cyst (a, void arrow)

Primary hydatid cyst as a cause of pseudotumor of the buttock

Lymphangioma appears as a well-circumscribed unicystic or multicystic, homogeneous, or heterogeneous mass.4,32 The lesion may show an isointense or hyperintense signal on Tl-weighted images and an isointense or hypointense signal on T2-weighted images with respect to the vitreous (Table 10.4) A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss. These small regions of high intensity are observed on T2 weighted MRI images (typically created using 3D FLAIR) within cerebral white matter (white matter. The lesion is discontinuous and nodular with peripheral enhancement, suggestive for a haemangioma. A haemangioma was confirmed with MRI, showing a T2 hyperintense lesion that is homogenous hyperintense during the contrast-enhanced T1w vibe dixon FS delayed phase which is similar to the bloodpool (image 3b and 3c In this disorder, the sella appears empty because it is filled with cerebrospinal fluid, which flattens the pituitary gland against the wall of the sella. The syndrome may be. Congenital. Primary. Secondary to injury (eg, ischemia after childbirth, surgery, head trauma, radiation therapy) The typical patient is female ( > 80%), obese (about 75%. The myxoid form is T1 isointense to hyperintense to skeletal muscle and T2 hyperintense to adipose tissue. Highly collagenous lesions have a hypointense signal on all MR images. [ 39 ] Contrast enhancement is typically diffuse but may be peripheral in lesions with cystic changes or extracellular matrix [ Figure 13 ]

Spots on an MRI: White Matter Hyperintensitie

The range of follow-up duration was 3 to 35 months (mean interval, 17.2 months; SD, 12.3 months). At one disk level in a single patient, hyperintensity of the lesion at initial T2-weighted imaging had resolved at 13-month follow-up, whereas enhancement persisted In general, the solid varieties of RCC lesions are well-circumscribed, cortically based, heterogeneously T2 hyperintense, and isointense on noncontrast T1W sequences, and exhibit avid arterial-phase enhancement. In some cases, the histologic subtype can be suggested by specific imaging features We do know that Migraines can cause white matter lesions, also called white matter hyperintensities (WMH), to form on the brain. White matter is the whitish part of the brain that is made up of cells called axons. Axons facilitate nerve communication. White matter hyperintensities are sections of the white matter that appear as brighter white. The typical appearance of brain abscess on MRI is a ring-enhancing lesion that is T2-hyperintense with low or intermediate signal intensity on T1-weighted imaging (T1WI) (Figure 4). Central restricted diffusion is often present on DWI with corresponding low ADC values

Lesions are T2 hyperintense and may demonstrate enhancement or diffusion restriction in the acute phase of demyelination; enhancement may persist for up to 2 months. Chronic demyelination often leads to cord atrophy. In terms of demographics, MS is more common in women and often presents in the third to fifth decades of life MRI demonstrates hypo- to isointensity of the lesions on T1WI and mild hyperintensity on T2WI, unless there is a hemorrhagic component, in which case the metastatic foci may be T1 hyperintense and T2 hypo- to isointense. On postcontrast imaging,. A T2 hyperintense brainstem lesion with mass effect on adjacent structures, surrounding the cysterns, fourth ventricle, sylvian acqueduct and/or cerebellum are the MR features of a brainstem glioma. The three most frequent groups of brainstem gliomas in children, based on anatomy and clinical behavior, are: Diffuse intrinsic pontine glioma. Figure 2: Within the superficial aspect of the deltoid muscle, there is an ovoid, well-circumscribed lesion, which is hypointense to muscle on T1-weighted images (2A) and hyperintense on fluid sensitive sequences (2B,2C,2D), measuring up to 4.2 cm, with lobulated margins, a thin peripheral capsule, and a few thin septations (arrowheads)

The Multiple Sclerosis Lesion Checklist - Practical Neurolog

With simple fluid, T1 and T2 are isointense to simple fluid (CSF), but with infection or hemorrhage products, the increased protein concentration as well as cellular debris and iron from hemoglobin can result in varying degrees of T1 hyperintensity and variable hypo- or hyperintensity on T2 (Figure 2.42). Any of these modalities may demonstrate. Introduction Progressive brain atrophy, development of T1-hypointense areas, and T2-fluid-attenuated inversion recovery (FLAIR)-hyperintense lesion formation in multiple sclerosis (MS) are popular volumetric data that are often utilized as clinical outcomes. However, the exact clinical interpretation of these volumetric data has not yet been fully established

What Does Hyperintensity Mean On An Mri Report

Pancreatic cystic lesions are being diagnosed with increasing frequency in asymptomatic patients or incidentally through investigation of an unrelated presenting symptom For the evaluation of lesions by MRI, T1- and T2-weighted images remain a basic requirement for lesion characterization (1-3). In general, owing to their high cellular water content, the majority of solid lesions in the female pelvis appear hyperintense on T2-weighted images. In contrast, a frequently see BACKGROUND AND PURPOSE : T1-, T2-, and proton density (PD)-weighted sequences are used to characterize the content of cystic intracranial lesions. Fluid-attenuated inversion recovery (FLAIR) MR sequences produce T2-weighted images with water signal saturation. Therefore, we attempted to verify whether FLAIR, as compared with conventional techniques, improves the distinction between. White matter hyperintensities (WMH) seen on T2WI are a hallmark of multiple sclerosis (MS) as it indicates inflammation associated with the disease. Automatic detection of the WMH can be valuable in diagnosing and monitoring of treatment effectiveness. T2 fluid attenuated inversion recovery (FLAIR) MR images provided good contrast between the lesions and other tissue; however the signal. Fig 3 (A) T1-weighted, (B) T2-weighted, (C) fluid-attenuated inversion recovery, and (D) postcontrast T1-weighted magnetic resonance images showing multiple cystic lesions in the cerebral and cerebellar hemispheres. The cyst followed fluid signal on magnetic resonance imaging (hypointense to isointense relative to CSF on T1-weighted, hyperintense on T2-weighted, and suppressed on fluid.
