Digital subtraction angiography (DSA) of the spinal cord was performed in 6 patients using selective intra-arterial injections of contrast material. Two arteriovenous malformations of the spinal cord, 1 dural fistula, and 1 case of multiple hemangioblastomas were studied. Contrast and spatial resolution were satisfactory for defining normal and abnormal vascularity while reducing examination time, contrast dosage, patient discomfort, and film cost. The only significant limitation was misregistration artifacts seen on lateral views encompassing the diaphragm.
对6例患者进行了脊髓数字减影血管造影（DSA），采用选择性动脉内注射造影剂。研究了2例脊髓动静脉畸形、1例硬脊膜瘘和1例多发性血管母细胞瘤。在减少检查时间、造影剂用量、患者不适和胶片成本的同时，造影和空间分辨率对于界定正常和异常血管情况而言令人满意。唯一显著的局限性是在包括膈肌的侧位片上出现的配准伪影。
