The value of susceptibility weighted magnetic resonance imaging in evaluation of patients with familial cerebral cavernous angioma

We investigated the imaging features of Cavernous angioma (CA) lesions and the value of Susceptibility-weighted imaging (SWI) by comparing with T2*-weighted gradient echo (GRE) sequences in patients with familial CA disease. We retrospectively evaluated 19 familial CA patients (8 men, 11 women; mean age, 36 years). T1-weighted, T2-weighted, T2*-weighted GRE, and SWI sequences were performed to all patients. The numbers of CA lesions seen on T2*-weighted GRE and SWI sequences were analyzed. The correlations between the numbers of lesions on both sequences with age were evaluated. CA lesions were classified according to the classification of Zabramski et al. The number of CA lesions was higher on SWI than T2*-weighted GRE significantly (P
