| ［摘要］ 目的 探讨磁敏感加权成像（susceptibility weighted imaging，SWI）在脑外伤微出血诊断中的应用价值。方法 对47例临床及手术证实脑外伤微出血患者，行常规MRT2WI、T2FLAIR、T1FLAIR、DWI及SWI序列扫描,对常规序列对脑外伤微出血的检出率与SWI序列比较。结果 SWI序列检出47例脑外伤微出血患者，表现为斑点状、小斑片状及条状低信号影。常规T2WI、T2FLAIR、T1FLAIR、DWI序列分别检出14例、23例、12例、29例。结论 SWI序列对颅内微小出血的检出率高于常规序列，对脑外伤微出血早期诊断有较高价值。 |

| ［Abstract］ Objective To explore the diagnostic value of susceptibility weighted imaging(SWI) in patients with traumatic cerebral microbleeds.Methods MRI data of 47 patients with traumatic cerebral microbleeds proved by clinical manifestation and operation were retrospectively analyzed. MRI data included T2WI, T1fluid attenuated inversion recovery(FLAIR), T2FLAIR，DWI and SWI. The detection rates between SWI and conventional sequences were compared.Results Forty-seven patients with traumatic cerebral microbleeds were showed punctate small patchy and linear low signal by SWI,and 14, 23, 12, 29 patients with traumatic cerebral microbleeds were showed by T2WI，T2FLAIR，T1FLAIR，DWI respectively.Conclusion SWI is sensitive to traumatic cerebral microbleeds and it has high value in early diagnosis of traumatic cerebral microbleeds. |
