| 摘 要： | 目的 评价MRI对脊髓血管畸形的诊断价值。资料与方法 24例临床诊断为脊髓占位的患者行MR平扫、增强、3D-CISS和三维增强磁共振血管成像(3D-CE-MRA)。结果 24例中23例可显示畸形血管：髓内3例,髓外16例,髓内外4例。对供血动脉、引流静脉的显示MR平扫不及3D-CE-MRA。1例MRI显示硬膜下血肿,未见畸形血管。结论 MR平扫是脊髓血管畸形最敏感的首选检查方法,3D-CE-MRA有助于脊髓畸形血管的显示。

| Abstract: | Objective To evaluate MRI and MR angiography (MRA) in the diagnosis of spinal vascular malformation.Materials and Methods Both plain and enhanced MR scanning, 3D-CISS and CE-MRA were performed in 24 patients with clinically-diagnosed spinal space-occupying lesion. The imaging findings were analyzed.Results Of the total 24 cases, vascular malformation was seen in 23. The lesions were intra-medullary (n=3), extra-medullary (n=16) or both intra- and extra-medullary (n=4). The remaining one case had subdural hematoma and showed no vascular deformity.Conclusion Plain MRI is the most sensitive technique to demonstrate spinal vascular malformation. CE-MRA is superior to MRI in displaying the deformed vessels. |
