Synergistic Contrast MRI (scMRI), a general analysis to explain the T1/T2 "paradox" above where two tissue properties may augment or oppose one another depending on the pulse sequence used.). Curr Probl Diagn Radiol. [5] Hyperintensities appear as "bright signals" (bright areas) on an MRI image and the term "bright signal" is occasionally used as a synonym for a hyperintensity. 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 lesions, white matter hyperintensities or WMH)[1][2] or subcortical gray matter (gray matter hyperintensities or GMH). However, when T2 and D* are both decreased as with many prostate tumors, the T2 contrast is negative and the D* contrast is positive. How often have you read, "There are small scattered foci of signal abnormalities (T2 hyperintensities or increased FLAIR signal) in the cerebral white matter indicative of demyelinating disease, chronic white matter ischemia due to microvascular disease, or gliosis from an infectious/inflammatory disease process," or words just like them in your This site needs JavaScript to work properly.
