Intravenous Gd-diethylenetriamine pentaacetic acid was used in 16 patients to differentiate between syringomyelia, syringomyelia in association with tumor, and cystic tumor in the spinal cord. Contrast enhancement occurred in all 12 histologically proven cases of tumor and enabled clear demarcation of neoplastic tissue from syrinx or cyst. Eleven of the twelve tumors seen in association with spinal cord cavitation were malignant; all tumors apart from one (a schwannoma) were intramedullary in location. Enhanced scans were more helpful than unenhanced scans in diagnosing and defining the extent of tumors associated with a syrinx or cyst.
16例患者静脉注射钆-二乙烯三胺五乙酸，以鉴别脊髓空洞症、合并肿瘤的脊髓空洞症和脊髓囊性肿瘤。在所有12例经组织学证实的肿瘤病例中均出现了对比增强，能够清晰地将肿瘤组织与空洞或囊肿区分开来。与脊髓空洞相关的12例肿瘤中有11例为恶性；除1例（神经鞘瘤）外，所有肿瘤均位于髓内。增强扫描在诊断和确定与空洞或囊肿相关的肿瘤范围方面比未增强扫描更有帮助。
