The presence and number of lobar intracerebral macrohemorrhage (ICH), cerebral microbleeds (CMBs) and cortical superficial siderosis (cSS) were evaluated on T2-GRE. The distribution and severity of cSS was classified as focal (restricted to ≤3 sulci) or disseminated (≥4 sulci) (Roongpiboonsopit, Neurology, 2016).
