The value of 3.0 T MR susceptibility-weighted imaging in detection of cerebral microbleedings in patients with stroke

Objective To assess the value of susceptibility-weighted imaging(SWI) in cerebral microbleedings(CMBs)in patients with stroke. Methods 65 stroke patients performed MRI, including routine T1 Flair, T2 WI, T2 Flair and SWI. The signal characteristics, distribution of CMBs in stroke patients in SWI were evaluated. Results In 57 patients, 25 patients with ischemic storke, 32 patients iwth hemorrhagic stroke. A total of 489 CMBs occured predominantly in cortex-subcortical area(n =221, 45.2%), basal ganglia(n=175, 35.8%), thalamus(n=45, 9.2%), brain stem(n =28, 5.7%), others(n =20, 4.1%).Coclusion SWI has obvious advantage in the detection of CMBs, the characteristic and number of CMBs could be displayed clearly, and its anatomic location could be positioned accurately.
