食管癌放射治疗模拟定位

Simulation in radiotherapy for esophageal carcinoma

在食管癌的放射治疗中,精确定位是提高食管癌放疗局部控制率的关键,CT模拟定位是食管癌放射治疗中提高肿瘤剂量,减少并发症,提高肿瘤控制率的很好的方法,PET/CT融合更多地显示有治疗意义的征象,对放射治疗的准确定位有很大价值。

Accurate simulation is the key of improve local control rates for radiotherapy esophageal carcinoma. CT simulation is an excellent tool that advances our capabilities of 3-D conformal radiation therapy so that higher radiation dose can be delivered to the target with a corresponding expectation of increased tumor control, possibly combined with a decrease in morbidity for radiotherapy esophageal carcinoma. PET/CT has an advantage in delineation of lateral extension of esophageal tumor, has more values for simulation in radiotherapy esophageal.
