Thirty-five patients with a variety of spinal cord tumors were studied by magnetic resonance imaging (MRI). In 22 out of these cases, the efficacy of Dimeglumine gadopentetate (Gd-DTPA) in enhancing MRI was also investigated. The results were as follows: (1) MRI was capable of discerning the level of tumors. (2) MRI was able to distinguish intramedullary from extramedullary tumors. MRI, however, could not always differentiate extradural from intradural tumors. (3) Some cases of lipoma, arteriovenous malformation and hematoma were diagnosed by MRI. (4) Gd-DTPA was found to be effective in enhancing MRI in all cases of spinal cord tumors with exception of two cases of arteriovenous malformations. In conclusion, MRI is very useful in diagnosing spinal cord tumors. MRI, when enhanced with Gd-DTPA, is capable of revealing the content of tumors but also differentiating intramedullary tumors from surrounding edema and syrinx.
对35例患有各种脊髓肿瘤的患者进行了磁共振成像（MRI）研究。其中22例还研究了钆喷酸葡胺（Gd-DTPA）增强MRI的效果。结果如下：（1）MRI能够辨别肿瘤的位置。（2）MRI能够区分髓内肿瘤和髓外肿瘤。然而，MRI并不总能区分硬膜外肿瘤和硬膜内肿瘤。（3）MRI诊断出了一些脂肪瘤、动静脉畸形和血肿病例。（4）除两例动静脉畸形外，Gd-DTPA在所有脊髓肿瘤病例中增强MRI均有效。总之，MRI在诊断脊髓肿瘤方面非常有用。使用Gd-DTPA增强后的MRI不仅能够显示肿瘤的内容，还能区分髓内肿瘤与周围水肿及空洞。
