摘　　要：目的:对比磁敏感成像(SWI)与多层螺旋 CT(MSCT)在脑微出血灶(CMB)中的诊断价值。方法:回顾性分析 36 例脑微出血灶患者 SWI 及 MSCT 图像。分别计数两种检查方法检出皮层、皮层下白质区、基底节、丘脑区、脑干、小脑等部位 CMB 灶总数量,比较两种方法检出 CMB 灶数目的差异,并分析该两种方法在不同脑部位检出 CMB 病灶数目的差异。结果:SWI 序列与 MSCT 两种方法检出 CMB 灶总个数及在不同脑部位检出 CMB 病灶个数均存在统计学差异(P<0.01)。SWI 序列对 CMB 病灶的检出数量高于 MSCT。结论:相比于MSCT,SWI 序列对 CMB 病灶的检出更敏感,检出率更高。Objective: To compare the diagnostic value of magnetic sensitive imaging (SWI) and multi?slice spiral CT (MSCT) in cerebral microbleeds. Methods: The SWI and MSCT images of 36 patients with cerebral microbleeds were retrospectively analyzed. The number of CMB foci in the cortex, subcortical white matter area, basal ganglia, thalamus area, brainstem, cerebellum and other parts was detected by above mentioned two methods. The difference of the total number of CMB lesions detected by the two methods was compared, and differences in the number of CMB lesions at different brain sites were analyzed. Results: There were significant differences in the total number of CMB lesions detected by SWI and MSCT, and the number of CMB lesions detected in different brain regions were also statistically different (P<0.01). The detection rate of CWB lesions by SWI sequence was significantly higher than that of MSCT. Conclusion: Compared with MSCT, SWI sequences are more sensitive to the detection of CMB lesions, and the detection rate is relatively higher.
