鼻咽癌放疗后所致的放射性脑病(RBD),有关临床、病理及CT方面国内外已有一些研究,但磁共振成像(MRI)观察尚未见报道。MRI显示RBD敏感性高,特别是显示脑干病损更优于其他任何方法。现将20例RBD的MRI观察情况报道如下。 材料与方法 一、一般资料:男性11例,女性9例。年龄15～72岁,平均45.2岁。低分化鳞癌19例,泡状核细胞癌1例。放疗结束行MRI检查最短7个月,最长4.5年,平均18.2个月。
Radioactive encephalopathy (RBD) caused by radiotherapy of nasopharyngeal carcinoma has been studied at home and abroad in clinical, pathological and CT aspects, but magnetic resonance imaging (MRI) observations have not been reported. MRI shows high sensitivity of RBD, especially brain stem lesions are better than any other method. Now 20 cases of RBD MRI observations are reported below. Materials and Methods 1. General information: 11 males and 9 females. Age 15-72 years old, average 45.2 years old. There were 19 cases of poorly differentiated squamous cell carcinoma and 1 case of vesicular nucleus cell carcinoma. The end of radiotherapy MRI examination of the shortest 7 months, up to 4.5 years, an average of 18.2 months.
