摘要 为探讨MR弥散加权成像(diffusion weighted imaging,DWI)在不典型脊柱结核诊断中的应用价值,回顾性分析6例经手术病理证实的脊柱结核患者的弥散成像资料。结果,常规MRI显示:T1WI病变椎体呈均匀低信号;T2WI骨质破坏区呈不均匀高信号;T2WI压脂序列骨质破坏区呈略高信号。2例椎间隙轻度狭窄,仅1例可见小范围冷脓肿形成,常规T1WI、T2WI未见显示,增强后呈小环状强化。弥散图显示:病变椎体呈中、高信号改变,间盘无明显异常改变。测得病变椎体的ADC值明显较临近正常椎体升高,本组病例的范围为0.855×10^-3~1.150×10^-3mm^2/s,平均约1.02×10^-3 mm^2/s。表明常规MRI特征结合弥散加权成像定量研究,有助于提高不典型脊柱结核的诊断准确率。
