自1987、6月～1988、5月收治53例确诊为鼻咽癌患者进行 CT 扫描、常规临床检查、TRS 放疗设计及放疗。CT 扫描较常规临床检查更敏感,表现在:1、早期发现鼻咽癌粘膜下软组织浸润。2、鼻咽腔侧壁及后壁的受浸。3、可发现鼻咽腔外扩展范围如:咽旁间隙(62.3%),鼻腔(20.1%),鼻副窦(28.3%)等。4、CT 扫描对鼻咽原发肿瘤、受浸范围及 T 分期更为准确。籍助 CT 扫描及放疗计划系统即可制定一个良好的放疗设计。
From 1987, June to May 1988, and May, 53 patients diagnosed as nasopharyngeal carcinoma received CT scan, routine clinical examination, TRS radiotherapy design, and radiotherapy. CT scans are more sensitive than routine clinical examinations. They are: 1. Early detection of submucosal soft tissue invasion of nasopharyngeal carcinoma. 2. Infiltration of the lateral wall and posterior wall of the nasopharyngeal cavity. 3, can be found outside the scope of nasopharyngeal expansion such as: parapharyngeal space (62.3%), nasal cavity (20.1%), nasal paranasal sinus (28.3%) and so on. 4. CT scans were more accurate for primary nasopharyngeal tumors, range of immersion, and T-stage. With the aid of the CT scan and radiotherapy planning system, a good radiotherapy design can be developed.
