| 摘 要： | 目的 评价低场强MR对脑动静脉畸形的诊断价值。方法 回顾2 2例经低场强MRI检查,并通过数字减影血管造影(DSA)证实(5例为进一步手术病理证实)的脑动静脉畸形(AVM)病例,分析其MRI表现。结果 低场强MRI检查中,异常的血液流空征象为直接征象,脑内及蛛网膜下腔出血,脑组织萎缩、铁环征等均为间接征象。结论 低场强MRI对AVM有定性定位诊断价值。

| Abstract: | Objective To evaluate the diagnostic value of cer eb ral arteriovenous malformation (AVM) with low field MR. Methods This paper reported low field MRI examination result of 22 cerebral AVM cases an d analyzed the value for diagnosing AVM. Results In low field MR I scan, abnormal blood stream as the direct sign was found in 12 cases and intra cranial and cranial arachnoid hemorrhagie, brain atrophy as the indirect signs w ere found in 13 cases. All these direct and indirect signs were found in low fie ld MRI scan. Conclusions Low field MR is a valuable modality for locating and qualitative diagnosis of AVM. |
