In 14 cases of unspecific infectious spondylodiscitis 11 patients underwent MR tomography, 3 of them were followed up. At the acute stage of the disease characteristic MR patterns are revealed. The main symptoms are 1) transdiscal hypointensity of the affected segment in T1-weighted images without differentiation of disk and adjacent vertebral bodies as well as 2) the manifestation of a hyperintense signal of diseased disks, vertebral bodies and paravertebral inflammation on T2-weighted images. A signal void is produced by sclerotic reactions of spongiosa. The formation of intraspinal abscesses and the compression of the spinal cord are clearly outlined by MR. When therapy is successfully applied, signal alterations largely normalize.
在14例非特异性感染性脊椎椎间盘炎患者中，11例接受了磁共振断层扫描，其中3例进行了随访。在疾病急性期可发现特征性的磁共振成像表现。主要症状为：1）在T1加权图像上，受累节段椎间盘呈低信号，椎间盘与相邻椎体无区分；2）在T2加权图像上，病变椎间盘、椎体及椎旁炎症表现为高信号。松质骨的硬化反应产生信号缺失。磁共振成像能清晰显示脊髓内脓肿的形成及脊髓受压情况。当治疗成功应用时，信号改变大多恢复正常。
