| 摘 要： | 目的:探讨鼻咽癌放射性脑病(REP)147例的MR表现特征。方法:回顾性分析147例鼻咽癌REP患者MR常规加增强扫描的影像学特点。结果:147例鼻咽癌REP中颞叶损伤122例(83.0%),脑干损伤13例(8.8%),颞叶+脑干混合损伤12例(8.2%),共检出224侧颞叶及25例脑干REP病灶。颞叶型REP:形态多样,水肿(96.9%)及强化(94.7%)常见,30.8%有占位效应。脑干型REP:多数为单发(22/25),体积较小(≤2.0 cm),多均匀强化,水肿及占位效应较轻,动态观察可见病灶消失(7/25),明显缩小(4/25)。结论:鼻咽癌REP的MR表现具有特征性及动态变化的特点。颞叶仅1侧病灶消失;脑干REP经治后部分病灶可缩小或消失,并伴有脑干萎缩。

| Abstract: | OBJECTIVE:To detect the characteristics of magnetic resonance(MR) imaging of radiation encephalopathy(REP) in patients with nasopharyngeal carcinoma(NPC).METHODS:The characteristics of MR scanned by routine and enhancement means were analyzed retrospectively in 147 postradiotherapeutic patients with NPC.RESULTS:Among them,temporal lobe injury,brainstem injury both injury had appeared in 122(83.0%),13(8.8%) and 12(8.2%) patients,respectively.Totally there were 224 sides of temporal lobe injury and 25 cases o... |
