Abstract： 目的 探讨多层螺旋CT血管成像(CTA)在脊髓血管病变诊断中的价值.方法 对MRI及临床表现符合脊髓血管病的10例患者行CTA.其中7例于1周内行DSA检查,4例行手术治疗.CT扫描采用Toshiba Aquilion 64层CT扫描机,采用多平面重组、曲面重组、最大密度投影、容积重组方法进行图像后处理.主要从分型、显示病变范围、供血动脉、瘘口及引流静脉等方面对CTA图像进行评价,并与DSA及手术结果对照.结果 10例患者CTA均显示了脊髓血管畸形;3例为髓内动静脉畸形,2例为髓周动静脉瘘,5例为硬脊膜动静脉瘘.所有病例均清楚显示病变范围及引流静脉,除1例患者有2根血管为假阳性,其余患者均清楚显示供血动脉并与DSA检查结果一致.结论 CTA对脊髓血管病变的诊断有较大价值,可作为DSA检查前的筛选检查.
