摘　　要：目的:探讨MRI对化脓性脊椎炎的诊断价值。方法:回顾分析12例经手术病理或临床证实的化脓性脊椎炎的MRI表现。所有病例均行SE序列T1WI、T2WI扫描和短时反转恢复(STIR)序列扫描,2例同时行Gd-DTPA增强扫描。结果:12例共累及27个椎体,14个椎间盘。9例发生在腰椎,1例胸腰椎,2例腰骶椎。6例12个椎体为相邻椎体终板下局限长T1、长T2信号改变;另6例15个椎体为全椎弥漫性长T1、长T2信号改变,椎体未见明显塌陷。14个受累椎间盘也以长T1、长T2信号为主,9例椎间隙变窄。12例均有不同程度椎旁软组织肿胀、增厚,5例累及硬膜外间隙。2例Gd-DTPA增强扫描病变椎体、椎间盘、椎旁软组织明显异常强化。结论:MRI对全面显示化脓性脊椎炎的椎体、椎间盘的破坏程度、范围,周围软组织肿胀及椎管内累及的敏感性、准确性较高,具有明显优势,可作出早期诊断。Objective： To evaluate the value of MRI in the diagnosis of pyogenic spondylitis （PS）. Methods： MRI tings in 12 patients with pathologically or clinically confirmed PS were retrospectively analyzed. SE T1WI, T2WI and STIR were carried out in all cases. Gd - DTPA enhanced scanning was performed in 2 cases. Results： Of 12 eases, 27 vertebral bodies and 14 intervertebral discs were involved. The lesions developed at lumbar spines in 9 cases, both thoracic and lumbar spins in 1 and both lumbar spins and sacrum in 2 cases, localized long T1 and long T2 signals in adjacent sub - endplate of vertebral bodies showed in 12 vertebral bodies of 6 cases, diffused long T1 and long T2 signals in other 15 vertebral bodies of 6 cases, The involved intervertebral discs displayed mainly long T1 and long T2 signal. Tumefaction of paravertebral soft tissue at varied degrees showed in 12 cases, extradural space was involved in 5 of 12 cases, Obviously abnormal enhanced vertebral bodies, intervertebral discs and paravertebral soft tissues after Gd - DTPA injection showed in 2 cases. Conclusion： MRI was sensitive and accurate in the early diagnosis of PS.
