Abstract W MP119: Sensitivity and Reliability of MRI SWI Compared With GRE Sequences for Detecting Microbleeds in a Community Population

Background: MRI susceptibility-weighted imaging (SWI) provides better contrast and is typically done at higher spatial resolution than MRI T2*-weighted gradient-recalled echo (GRE), increasing the sensitivity for cerebral microbleed (CMB) detection. However, few studies have implemented SWI and GRE in the same scan session, and there is uncertainty regarding whether findings on SWI are comparable to findings on GRE. We compared the sensitivity …
