摘要:
目的分析脑海绵状血管瘤常规MRI与磁敏感加权成像(susceptibility weighted imaging，SWI)的影像学表现，并探讨SWI对脑海绵状血管瘤的诊断价值。方法 回顾性分析 经手术病理证实的18例海绵状血管瘤的常规MRI及SWI影像资料，记录常规MRI T2WI、T1WI及SWI检出病灶数并测量最大病灶的大小。结果 18例海绵状血管瘤，T2WI检出病灶共25个 ，T1WI检出病灶共21个，SWI检出病灶共47个。T2WI和T1WI呈 “爆米花”样高、低混杂信号，周围绕以低信号环或高信号环；SWI表现为明显低信号。SWI测得的病灶范围较T2WI、 T1WI测得的范围大，且微小病灶显示多。但SWI测得的病灶大小与T2WI、T1WI比较差异没有统计学意义(P>0.05)。结论 磁敏感成像对海绵窦血管瘤的显示优于T1WI、T2WI 成像。结 合常规磁共振成像及SWI，可更好地显示颅内海绵状血管瘤的病变范围及微小病灶。
Abstract:
Objective To evaluate the diagnostic value of SWI in cerebral cavernous angioma by analyzing the imaging findings of conventional MRI and SWI.Methods A retrospective analysis of 18 cases confirmed by operation and pathology in patients with cerebral cavernous angioma of the conventional MRI and SWI image,recording the number of cerebral cavernous angioma in the conventional MRI T2WI,T1WI and SWI,and measuring the size of the lesion.Results 18 cases of cerebral cavernous angioma were detected by T2WI,T1WI and SWI were 25,21,47 lesions respectively.The signal of T2WI and T1WI were mixed high and low,surrounding by low signal ring or high signal ring,SWI showed low signal.Descending orders of the size of lesion were SWI,T2WI and T1WI.SWI showed more small lesions.But no significant differences in SWI,T2WI and T1WI measured lesion size (P>0.05).Conclusion SWI showed cerebral cavernous angioma better than T1WI and T2WI imaging.Combined with conventional MRI and SWI can display the cerebral cavernous angioma better and more small lesions.
