Few previous studies have found that the atypical/malignant meningiomas tend to be markedly hyperintense on diffusion weighted images (DWI) and exhibit markedly decreased value on apparent diffusion coefficient (ADC) imaging when compared with normal brain parenchyma, while the benign meningiomas have a variable appearance on diffusion weighted images and tend to have higher ADC values compared with normal brain.6,9,10 However these already conflicting results needs to be validated in our population, where tuberculomas are common confounders for the meningiomas and may give a similar appearance with caseous material simulating signals of calcification on screening MRI.
Lesions with peripheral globular contrast enhancement in the arterial phases and being hyperintense in the late venous phases compared to the normal liver parenchyma were evaluated as hemangioma (14).
The secondary MRI endpoints included the number of new or enlarging hyperintense T2-weighted brain MRI lesions over 12 months, number of gadolinium-enhanced brain MRI lesions at month 12 and % change from baseline in whole brain volume at month 12.
Hepatobiliary MRI contrast agents have been successfully used for the diagnosis of FNH lesions, which are typically isointense or hyperintense to the surrounding parenchyma on hepatobiliary phase (6, 7).
MR imaging typically demonstrates T2 hyperintense signal.
The primary endpoint is the number of new or newly enlarging T2 hyperintense lesions at week 48.
A few other metabolic disorders, such as organic aciduria, cortical basal ganglionic degeneration, and early-onset levodopa-responsive parkinsonism, also show hyperintense signals within the basal ganglia.
The MRI of the floor of the mouth: in the midline, a clearly demarcated, oval, cystic lesion was observed, with dimensions of 31 x 29,5 x 19 mm, divided with a capsule from the surrounding muscles of the tongue, beyond the mylohyoid muscle, filled with liquid content, with homogenous hyperintense signal in T1W and T2W images.
While lower ADC values indicate malignancy (hypointense with ADC, hyperintense with DWI), higher ADC values favor benignancy (hyperintense with ADC, hypointense or hyperintense with DWI).
TUESDAY, June 12, 2018 (HealthDay News) -- White matter hyperintense lesions (WMHs) in patients with reversible cerebral vasoconstriction syndrome (RCVS) change over time in a manner that parallels disease severity, according to a study published online June 4 in JAMA Neurology.
The transitional zone of the prostate gland comprised a macrolobulated heterogeneous hyperintense mass with a hypointense capsule on T2-weighted images (WIs) (Figure 1) The prostatic mass exhibited central and peripherally hyperintense areas within the mass on T1-WIs, compatible with mucin lakes (Figure 2).
Brain magnetic resonance imaging (MRI) of the patient showed T1 hyperintense signal and mild T2 and gradient recalled hypointense echo signal in the left basal ganglia region (Figure 1, 2).
