Objective To approach the applicate value of MRI susceptibility weighted imaging(SWI) on intracerebral hemorrhage(ICH). Methods Thirty-two ICH patients diagnosed by CT were examined by conventional MRI sequence and SWI scan. The display rate of lesion, distribution of cerebral microbleeds and volume of hemorrhage were evaluated according to those examinations. Results Seventy-five hemorrhagic focus were found out in 32 ICH patients. The positive rate of patients by MRI(TlWI and T2WI), Flair, SWI was 28.13％、65.63％、100％, respectively. And the relevance rate of ICH was 30.67%、45.33% and 100%.The positive rate and relevance rate by SWI was significantly higher than the other MR sequences(all P<0.05). The cerebral micmbleed lesions were found in 13 eases by SWI, and there were 25 cerebral micmbleeds in basal ganglia area, 5 in cerebella, 5 in brain stem, 3 in thalamus, 3 in cerebral codex. Conclusion SWI sequence is more sensitive than conventional MRI sequences to show intracerebral hemorrhage(ICH).There is great value for SWI in clinical application, and it is also a very important guide for clinical treatment.
