Four patients with paravertebral extension of advanced tuberculous intervertebral disk-space infection were studied by CT and MRI. In one patient gadolinium-DTPA (Gd-DTPA) was administered intravenously as a paramagnetic contrast agent. MRI showed the disk-space abnormalities and extension of the inflammatory process to best advantage in the coronal plane. This plane demonstrated in one image the spinal localization and the paravertebral extension of the inflammation. Gd-DTPA assisted in delineating the communication of the vertebral and paravertebral components of inflammation. This phenomenon introduces an additional diagnostic element into the evaluation of spondylitis. Although the features of advanced tuberculous spondylitis are conspicuously well shown with MRI, further experience is needed to evaluate the potential of MRI in detecting early tuberculous spondylitis in relation to nontuberculous spondylitis.
对4例晚期结核性椎间盘间隙感染伴椎旁扩展的患者进行了CT和MRI研究。其中1例患者静脉注射钆喷酸葡胺（Gd-DTPA）作为顺磁性造影剂。MRI在冠状面能最佳显示椎间盘间隙异常及炎症过程的扩展。该平面在一幅图像中显示了炎症的脊柱定位及椎旁扩展。Gd-DTPA有助于描绘炎症的椎体和椎旁成分之间的连通情况。这一现象为脊柱炎的评估引入了一个额外的诊断要素。尽管MRI能显著清晰地显示晚期结核性脊柱炎的特征，但仍需要更多经验来评估MRI在检测早期结核性脊柱炎与非结核性脊柱炎方面的潜力。
