目的探讨磁敏感加权成像(SWI)在脑血管畸形诊断中的临床应用价值.方法采用Siemens Sonata 1.5T MR扫描仪的T_1WI、T_2WI及SWI等序列对34例脑血管畸形患者进行前瞻性研究,以数字减影血管造影(DSA)或手术所见为参照标准,将SWI图像与常规MRI图像进行分析比较.结果 34例脑血管畸形患者共41个病灶,包括海绵状血管瘤19例,动-静脉畸形9例,脑静脉畸形6例.SWI图像对脑血管畸形病灶的显示与DSA或手术所见相一致.结论 SWI对脑血管畸形病灶显示清晰、准确.结合其他MR序列可以应用于临床对脑血管畸形的诊断.

Objective To discuss the clinical value of susceptibility weighted imaging (SWI) in the brain vascular malformations. Methods Imaging data of 34 patients with brain vascular malformations proved by digital subtraction angiography (DSA) or pathology obtained on Siemens Sonata 1.5T MR system were studied prospectively, and compared with those of conventional MRI (cMRI) and SWI. Results All 41 lesions of 34 patients with brain vascular malformations showed clearly by SWI. These patients were diagnosed by surgical findings or DSA. These nidus comprised 19 cavernous angiomas, 9 arteriovenous malformations and 6 cerebral venous malformations. Conclusion SWI should be used for clinical diagnosis of brain vascular malformations, and providing more complete and detailed information combining with other sequence.
