WebResearch suggests that DWI may be more sensitive than conventional MR when trying to distinguish a cystic mass from a brain abscess. This is because the purulence within a brain abscess is very hyperintense on DWI with corresponding low ADC values. Necrotic and cystic tumors have intermediate signal intensity on DWI with elevated ADC values. 10 WebFeb 6, 2013 · Brain magnetic resonance imaging (MRI) is the preferred and most sensitive modality after transient ischemic attack (TIA) or minor stroke.
