The results of contrast enhanced MRI in 36 patients with suspected spinal intradural tumours are described. All intramedullary tumors showed distinctive enhancement and solid tumors could be delineated clearly, even if they were not clearly visible on unenhanced scans. The differentiation between neoplasm and non-neoplastic syrinx was markedly improved. The sensitivity of MRI for demonstrating intradural extramedullary tumours was greatly improved by gadolinium DTPA and even small lesions or flat meningeal infiltrates could be visualised. In addition, gadolinium DTPA improved the delineation and localisation of larger lesions, even if they had already been seen on unenhanced images.
本文描述了36例疑似脊髓硬膜内肿瘤患者的对比增强磁共振成像（MRI）结果。所有髓内肿瘤均表现出明显强化，实体肿瘤即使在平扫时显示不清，也能清晰勾勒出来。肿瘤与非肿瘤性空洞的鉴别明显改善。钆喷替酸葡甲胺（gadolinium DTPA）大大提高了MRI对硬膜外髓外肿瘤的显示敏感性，甚至小病变或扁平脑膜浸润也能被观察到。此外，钆喷替酸葡甲胺改善了较大病变的轮廓显示和定位，即使这些病变在平扫图像上已经可见。
