鼻咽癌放射性脑损伤的临床磁共振影像特点分析

Radiation brain injury in nasopharyngeal carcinoma(NPC) analysis of the clinical magnetic resonance imaging characteristics

目的:分析鼻咽癌放射性脑损伤的磁共振影像特点,并分析其临床价值。方法:通过回顾性分析的方式,总结我院40例鼻咽癌放射性脑损伤患者磁共振影像特点,并研究其临床价值。结果:本次研究对象中,有37例患者的放射性脑损伤发生于双侧或单侧颞叶,磁共振影像表现为单侧或双侧颞叶(及颞叶)能够看到稍长或基本相等的T1信号,或看到稍长或很长的T2信号,并且出现不同程度的水肿和占位效应。结论:鼻咽癌放射性脑损伤疾病的磁共振影像会表现出一定特征,综合临床鼻咽癌疾病的放疗史综合判断,通常很容易诊断。

Objective To analyze the MRI features of radiation brain injury in nasopharyngeal carcinoma （NPC） and analyze its clinical value. Methods The MRI features of 40 patients with radiation brain injury in our hospital were analyzed retrospectively and the clinical value of MRI was analyzed. Results The object of this study, there are 37 cases of radiation- induced brain injury occurred in patients with unilateral or bilateral temporal lobe, magnetic resonance imaging showed unilateral or bilateral temporal lobe Cand temporal lobe） to be able to see the T1 signal or slightly longer is basically the same, or see the T2 signal slightly long or very long, and the different degrees of edema and mass effect. Conclusion MRI findings of radiation brain injury in nasopharyngeal carcinoma can show certain characteristics. It is usually easy to diagnose the clinical history of nasopharyngeal carcinoma by comprehensive evaluation of the radiotherapy history.
