三维适形放射治疗是以影像学为指导的放射治疗技术,肿瘤的准确分期和准确勾画肿瘤靶体积是三维适形放射治疗中的重要环节。~(18)F-氟代脱氧葡萄糖(~(18)F-FDG)PET能够提高肿瘤的诊断准确率、肿瘤分期的准确性,对恶性肿瘤治疗方案做出正确选择,对准确详尽地描绘肿瘤范围和肿瘤组织与周围正常组织的关系有极大帮助。
Three-dimensional conformal radiotherapy is an imaging-guided radiotherapy technique. Accurate staging of the tumor and accurately delineating the tumor target volume are important aspects of three-dimensional conformal radiotherapy. (18) F-FDG (~ (18) F-FDG) PET can improve the accuracy of tumor diagnosis, the accuracy of tumor staging, make the right choice for the treatment of malignant tumors, accurately and exhaustively describe the tumor The range and the relationship between the tumor tissue and the surrounding normal tissue are of great help.
