"T1: hypointense compared to white matter"
"T2: strikingly hyperintense"
"FLAIR: large areas of T2 hyperintensity suppressing on FLAIR - these are not macrocystic but rather represent the areas with abundant microcystic change - and is known as T2/FLAIR mismatch sign, shown to be predictive of absence of 1p19q co-deletion"
"T1 C+ (Gd): usually little or no enhancement"
"MR spectroscopy: elevated choline:creatine ratio"
"MR perfusion: there is reduced rCBV"
