| 摘 要： | 目的：研究3.0T场强下颈椎间盘突出压迫颈髓损伤早期的扩散张量成像（DTI）表现及其临床应用价值。方法：使用单次激发自旋回波平面回波（SE-EPI）序列,对30例健康志愿者及30例颈椎间盘突出患者行常规磁共振（MRI）和横轴面DTI扫描,在C3～7水平分别测量各间盘水平表观扩散系数（ADC）值和部分各向异性（FA）值。结果：正常脊髓C3～7水平间ADC及FA值无差别（F=0.66,P=0.6195;F=1.99,P=0.1027）,病例组受压部位和对照组的ADC值、FA值有统计学意义（t′=2.0930,P〈0.05;t=11.2136,P〈0.001）。在发现脊髓压迫早期损伤时,ADC值的敏感度73.33%,特异性100%,FA值的敏感度和特异度分别为83.33%和100%。结论：DTI对判断脊髓慢性压迫早期损伤有一定价值,FA值敏感性较高。
