目的 探讨磁共振多方位弥散加权成像(DWI)及表观弥散常数对急性脑干梗死的诊断价值.方法 24例急性脑干梗死患者,其中2例超急性期(<6 h)、22例急性期(6~72 h);中脑梗死2例,桥脑梗死21例,延髓梗死1例;均行MRI常规检查、T1WI、T2WI检查,并进行DWI和ADC值测量.结果 24例急性脑干梗死中,横轴位T2WI及DWI的横轴位、冠状位、矢状位三个方位清晰地显示病灶并能确定诊断13例(54.2%);T2WI不能清楚显示病灶信号及范围,而横轴位、冠状位、矢状位DWI、ADC图像能明确诊断9例(37.5%);T2WI阴性、DWI及ADC图像的横轴位不能确定诊断,但在DWI及ADC图像的冠状位、矢状位清晰地显示病灶能够确定诊断2例(8.3%).结论 DWI结合ADC图像,易发现的脑干较低位置的病灶,是目前诊断急性脑干梗死的最佳方法之一.
目的 探討磁共振多方位瀰散加權成像(DWI)及錶觀瀰散常數對急性腦榦梗死的診斷價值.方法 24例急性腦榦梗死患者,其中2例超急性期(<6 h)、22例急性期(6~72 h);中腦梗死2例,橋腦梗死21例,延髓梗死1例;均行MRI常規檢查、T1WI、T2WI檢查,併進行DWI和ADC值測量.結果 24例急性腦榦梗死中,橫軸位T2WI及DWI的橫軸位、冠狀位、矢狀位三箇方位清晰地顯示病竈併能確定診斷13例(54.2%);T2WI不能清楚顯示病竈信號及範圍,而橫軸位、冠狀位、矢狀位DWI、ADC圖像能明確診斷9例(37.5%);T2WI陰性、DWI及ADC圖像的橫軸位不能確定診斷,但在DWI及ADC圖像的冠狀位、矢狀位清晰地顯示病竈能夠確定診斷2例(8.3%).結論 DWI結閤ADC圖像,易髮現的腦榦較低位置的病竈,是目前診斷急性腦榦梗死的最佳方法之一.

Objective To investigate the diagnostic value of multidirectional diffusion weighted image (DWI) and apparent diffusion coefficient(ADC) image in acute brainstem infarction.Methods 24 cases of brainstem infarction included 2 cases in super acute stage,22 cases in acute stage.All cases were performed multidirectional DWI,ADC and T1 WI、T2 WI examination including of 2 cases of midbrain,21 cases of pons and 1 case of medulla.All of them were accompanied with infarction of other location.Results Among 24 cases there were 13 cases that their lesions displayed clearly and established by transverse T2WI,transverse、coronary or sagittal DWI、ADC and the diagnostic accuracy was 54.2%.In other 9 cases(37.5%) could not display the signal and extent of the lesions,but they could be confirmed by transverse、coronary or sagittal DWI 、ADC.Moreover there were 2 cases(8.3%) who were indicated accurately the diagnosis by coronary、sagittal DWI 、ADC.Conclusion Multidirectional DWI and ADC could show the location of lesions in the lower brainstem so the multidirectional DWI and ADC scan could be an excellent method for the diagnosis of the brainstem infarction.
