Nine cases of single segment vertebral osteomyelitis were included based on the single level of vertebral body involvement according to the MR findings. They were 3 cases with tuberculous infection and 6 cases with pyogenic infection. The vertebral body involvement was presented as abnormal signal changes (100%) and heterogenous enhancement (77.7%). They usually caused the cortical disruption in its anterior aspect (100%). It goes along the upward subligamentous spread (100%) most often, then the upper disc involvement (66.6%) and downward subligamentous spread (55.5%). The lower disc involvement is least common (11.1%). By using these criteria, the single segment vertebral osteomyelitis could be earlier diagnosed.
根据磁共振成像（MR）结果，基于椎体受累的单一节段纳入了9例单节段椎体骨髓炎病例。其中结核感染3例，化脓性感染6例。椎体受累表现为异常信号改变（100%）和不均匀强化（77.7%）。它们通常导致椎体前缘皮质破坏（100%）。最常见的是沿向上的韧带下蔓延（100%），然后是上位椎间盘受累（66.6%）和向下的韧带下蔓延（55.5%）。下位椎间盘受累最不常见（11.1%）。通过使用这些标准，可以更早地诊断单节段椎体骨髓炎。
