Abstract：Objective To investigate the diagnostic value of MR susceptibility weighted imaging in the cerebral microb‐leeds (CMBs) ,and the clinical significance of the cerebral microbleeds .Methods Conventional MR T1WI ,T2WI ,FLAIR and susceptibility weighted imaging were performed in totally 131 patients with suspected stroke ,the distribution of the cerebral microbleeds was analyzed .Results CMBs were found in 44 patients ,the number of CMBs were 197 ,and their location were the cortico‐subcortical region in 115(58 .38% ) cases ,basal ganglia in 49(24 .87% ) cases ,the brain stem in 17(8.63% ) cases ,thalamus in 8(4 .06% ) cases ,cerebellum in 8(4 .06% ) cases .Among 44 patients ,32 patients were found lacunes on basal ganglia ,white matter around sided ventricle ,and the brain stem .There were acute infarction in 15 cases ,hemorrhagic stroke with CMBs in 4 cases .Conclusion Marked advantages were shown in the detection of CMBs by susceptibility weighted imaging .The presence of microbleeds may be a direct maker of advancing small vessel diseases , and may have a risk of bleeding .
