The clinic and application valce of 3.0T magnetic resonance SWI in patients with hypertensive cerebral spontaneous mircrobleeds

Objective To explore the clinic and application value of susceptibility weighted imaging(SWI)in patients with hypertensive cerebral spontaneous microbleeds.Methods 53 patients with hypertension underwent SWI and conventional MRI sequences at 3.0T MR scanner(GE signa HDe).The imaging foundings and related clinical data were analyzed.Results The brain microbleeds were found in 32 cases of 53 cases with hypertension.The cerebral microbleeds appeared as dot、 round or elliptic hypointensive signal on SWI.The total number of micro hemorrhage was 887,with diameter from 0.3mm to 7.6mm.Cerebral microbleeds mainly located in cortex、 subcortex and basal ganglia in 32 patients,17 cases had complicated ischemic lesions,5cases had hemorrhagic lacunar infarctions,7 cases had hemorrhagic lesions and 3 cases had no clinical symptoms.Conclusion SWI is sensitive to visualize the hemorrhagic lesions in hypertensive cerebral microbleeds and it has predominant instrective value in diagnosis and treatment to patients complicated with ischemic and hemorrhagic lesions.
