"T2: hyperintense to grey matter 1"
"T1 C+ (Gd): typically no or minimal enhancement"

Expected headings
"PET"
"CT can be normal as lesions are often isodense to normal brain parenchyma. There is a relative lack of mass effect and distortion compared to the extensiveness of involvement. There may be an ill-defined asymmetry or subtle hypoattenuation of the involved brain parenchyma."
"Mass effect and enhancement are often minimal despite large portions of the brain being involved. There is a loss of grey-white matter differentiation and diffuse gyral thickening."
