Cerebral cortical T1 hyperintensity
Updates to Article Attributes
Body
was changed:
Cerebral cortical T1 hyperintensity or gyriform T1 hyperintensity refers to curvilinear hyperintense signal involving the cerebral cortex on T1 weighted-weighted images on brain MRI.
Causes include:
-
Accumulationaccumulation of denatured proteins and/or lipid-laden macrophages -
Accumulationaccumulation of methaemoglobin in cortical hemorrhagic infarcts- vascular thrombo-occlusive disease
- herpes simplex (HSV) encephalitis
- cortical contusion
