摘要 目的探讨功能磁共振弥散成像技术(DWI)+质子波谱分析技术(1HMRS)联合应用于早期急性放射性脑损伤的诊断。方法应用1·5T磁共振机的弥散成像技术+质子波谱分析技术对2例鼻咽癌病人在放疗前和放疗结束进行顶叶、颞叶扫描。结果放疗前,DWI成像2例病人未见异常,1HMRS扫描顶叶和颞叶的NAA、Cr、Cho在正常范围,放疗结束,DWI成像显示两侧颞叶脑深部不规则高信号影,DWI扫描,顶叶NAA、Cr、Cho在正常范围,颞叶A例NAA、Cr、Cho分别为25·46、30·18、55·17,B例的NAA、Cr、Cho分别为26·47、30·13、56·03。与放疗前比较,颞叶的DWI和1HMRS都呈现病理性影像学表现。结论功能磁共振弥散成像技术(DWI)+质子波谱分析技术(1HMRS)联合应用可以在影像学上反映早期急性放射性脑损伤。
