We compared intrathecal metrizamide-enhanced CT (metrizamide-CT) and magnetic resonance imaging (MRI) in the evaluation of 17 patients with clinical suspicion of lesions at the cervicomedullary junction. MRI was superior in imaging the position of the cerebellar tonsils and the size and extent of mass lesions. MRI and metrizamide-CT were equal in detecting syringomyelia. CT with and without IV contrast enhancement was necessary to detect calcium or defects in the blood-brain barrier within neoplasms.
我们比较了鞘内注射甲泛葡胺增强CT（甲泛葡胺CT）和磁共振成像（MRI）对17例临床怀疑颈髓交界处有病变患者的评估情况。在显示小脑扁桃体的位置以及肿块病变的大小和范围方面，MRI更具优势。在检测脊髓空洞症方面，MRI和甲泛葡胺CT效果相当。为了检测肿瘤内的钙质或血脑屏障缺陷，有必要进行静脉对比增强CT和未增强CT检查。
