目的：探讨腰椎ModiciⅠ型终板退行性变的高场强核磁共振诊断特点。方法：2012年10月-2014年10月收治腰椎ModiciⅠ型终板退行性变患者40例，所有患者均行高场强核磁共振检查，认真分析所有患者的核磁共振检查结果，总结诊断特点。结果：40例患者中共有98椎终板出现病变。病变主要分布：1椎位于 L2下缘，2椎位于 L3上缘，7椎位于L3下缘，10椎位于L4上缘，18椎位于L4下缘，17椎位于L5上缘，21椎位于L5下缘，19椎位于S1上缘。9椎(4例)患者MRI表现出抑脂序列信号弱，T1WI混杂高信号；其他受累椎体MRI均表现为T2WI信号增强，T1WI信号减弱，椎体边缘较毛糙，一部分边缘出现“毛刷样”的改变；并且邻近的退变的椎体终板一般呈“吻状”对称分布；平行于终板的椎间盘上下径变窄，T2WI信号减弱，出现椎间盘突出或膨出征象。结论：腰椎Modic Ⅰ型终板退变大多出现在S1上缘及L4～5上下缘节段，受累的椎体终板T2WI信号增强，T1WI信号减弱，平行于病变终板的椎间盘有常出现膨出或突出现象，但椎间盘未破坏，可为腰椎ModiciⅠ型终板退行性变与早期椎间盘的感染性病变的鉴别诊断提供依据。

Objective:To discuss Modici Ⅰ type of lumbar endplate degeneration of high field magnetic resonance diagnostic characteristics.Methods:40 patients with Modici Ⅰ type of lumbar endplate degeneration were selected from October 2012 to October 2014.All patients underwent high-field MRI,a careful analysis of the results of MRI in all patients,and summarizing the diagnostic features.Results:A total of 40 cases of patients with 98 vertebral endplate appear lesions.The lesions are mainly distributed as:l vertebral body at L2 lower edge,2 vertebral body at L3 on the edge,7 vertebral body at L3 lower edge,10 vertebral body at L4 on the edge,18 vertebral body at L4 lower edge,17 vertebral body at L5 on the edge,21 vertebral body at L5 lower edge, 19 vertebral on S1 margin.9 vertebrae(4 cases)of patients with MRI showed a fat suppression sequence of weak signals,T1WI high signal intensity;other vertebral body MRI showed increased T2WI signal,T1WI signal was weakened,vertebral edges relatively rough,some edge a "brush-like"change;and degeneration of adjacent vertebral endplate general was "kiss-shaped"symmetrical;parallel to the endplate of intervertebral disc of the upper and lower diameter became narrow,the T2WI signal decreased, intervertebral disc protrusion or bulging signs appear.Conclusion:Modic Ⅰ type lumbar endplate degeneration occurs mostly on the edge S1 and L4~5 upper and lower edge segments,involvement of vertebral endplate T2WI signal enhancement,T1W1 signal weakened,parallel to the disc endplate lesions have often appear bulging or prominent phenomenon,but the disc is not damaged,to provide the basis for differential diagnosis of lumbar Modici type endplate degeneration and early disc infective disease.
