PET—CT图像融合在非小细胞肺癌放疗靶区勾画中的应用

Application of PET-CT image fusion in delineation of radiotherapy target volume in non-small cell lung cancer

PET-CT融合图像在非小细胞肺癌（NSCLC）放疗靶区勾画中具有显著的优势。确定和勾画PET—CT融合图像的病变范围，并尽可能与病理标准接近，对NSCLC放疗具有至关重要的作用。

PET-CT image fusion has shown prominent advantage in the radiotherapy target volume delineation in non-small cell lung cancer（NSCLC）. Making sure and delineating the pathological changes scope with the PET-CT fusion picture, and making it as close to pathologic standard as possible, are crucial in NSCLC radiotherapy.
