Multidetector CT (MDCT) angiography is an imaging technique that can provide high-resolution and high-contrast images; however, published reports of MDCT angiography in the evaluation of spinal vascular malformations are limited. We present 2 cases in which MDCT angiography led to diagnosis of a type I (spinal dural arteriovenous fistula) in one and type IVA (perimedullary spinal cord simple arteriovenous fistula fed by a single arterial feeder) spinal vascular malformation, both confirmed by conventional angiography. MDCT angiography can localize the feeding vessel and the fistula, thus greatly reducing the amount of time required for conventional angiography.
多排螺旋CT（MDCT）血管造影是一种能够提供高分辨率和高对比度图像的成像技术；然而，关于MDCT血管造影在评估脊柱血管畸形方面的已发表报告有限。我们报告2例病例，其中MDCT血管造影分别诊断出1例I型（硬脊膜动静脉瘘）和1例IVA型（由单一动脉供血的脊髓髓周单纯动静脉瘘）脊柱血管畸形，二者均经传统血管造影证实。MDCT血管造影能够定位供血血管和瘘口，从而大大减少传统血管造影所需的时间。
