| 摘 要： | 目的分析磁敏感加权成像（SWI）在脑血管畸形诊断中的应用价值。方法2008年3月至7月间对6例颅内血管畸形患者经1．5TMR检查的资料进行回顾性分析，其中5例为海绵状血管瘤，1例为静脉畸形。SWI所得图像应用16mm厚度的最小密度投影重建，将SWI图像与常规MR序列比较。结果SWI对6例血管畸形患者的病灶均显示清楚。其中5例海绵状血管瘤患者常规MR序列发现5个海绵状血管瘤，而SWI发现了9个；结论SWI应作为脑血管畸形诊断的常规序列应用于临床，结合其他序列对脑血管畸形能提供更全面、准确的信息。

| Abstract: | Objective:To discuss the value of susceptibility weighted imaging (SWI) in the brain vascular malforma- tions.Methods:From March 2008 to July 2008,6 patients with brain vascular malformations,including 5 cases of cavern- ous angioma,1 case of venous malformation,were examined with a 1.5 TMR scanner.The images of SWI were reconstruc- ted by minimum intensity projection in 10 mm thickness.The comparison of SWI and conventional MR sequences was ob- tained.Results:SWI showed all the cases clearly.In 5 cases of patients with cavernous angioma,9 lesions were shown by SWI,only 5 shown by conventional sequence.Conclusion:SWI should be used in combination with other sequence,as a routine MR sequence for detecting brain vascular malformation and providing more complete and detailed information. |
