摘要

视交叉(OC)是头颈部肿瘤放疗中常常需要保护的危及器官,但视交叉解剖结构较复杂,且形态在人群中存在变异,CT图像上视交叉显示不清。因此,视交叉勾画教学在肿瘤放射治疗学研究生培养上显得尤为重要。通过在MR的矢状面识别OC与垂体柄在垂体窝的前后相对位置关系,教研究生区分勾画三种不同类型的OC,经过教学后,学生对视交叉勾画的准确性明显提高。

Abstract

Optic chiasm (OC) is a dangerous organ that often needs to be protected in radiotherapy of head and neck tumors, but the anatomical structure of OC is complex, and its morphology varies in the population, so the display of OC on CT images is not clear. Therefore, the teaching of visual cross delineation is particularly important in the cultivation of Postgraduates of tumor radiotherapy. By recognizing the relative position of OC and pituitary stalk in the anterior and posterior pituitary fossa on the sagittal plane of MR, postgraduates were taught to distinguish and outline three different types of OC. After teaching, the accuracy of students' cross vision was significantly improved.
