Overview
MRI
T1W: Typically iso to hypointense mass, however melanoma metastases are an exception to this rule (hyperintense due to the paramagnetic properties of melanin).
T2W: Typically hyperintense. If metastases are scattered the pattern may mimic vascular disease.
FLAIR: Typically hyperintense with hyperintense peritumoral edema.
T1 C+: The enhancement pattern can be uniform, punctuate, or ring-enhanced, but it is usually intense. Delayed sequences may show additional lesions, therefore contrast-enhance MR is the current standard for small met detection.
MRS: Intratumoral choline peak with no choline elevation in the peritumoral edema. Any tumor necrosis results in a lipid peak.
DWI: edema is out of proportion with tumour size and appears dark on trace-weighted DWI. Nuclear medicine
