ABSTRACT
Objective To study 18F-deoxyglucose-positron emission tomography and CT fusion (FDG PET) in three dimensional conformal radiotherapy for non-small -c ell lung carcinoma (NSCLC). Methods Gross tumor volume (GTV) of 13 NSCLC patient s were determined by FDG PET and CT separately (GTV PET-CT and GTV CT ), which were then compared. Results Except 2 patients, all the other patients' GTV PET-CT dif fered from their GTV CT. Compared with GTV CT, GTV PET-CT was in creased by an avera ge of 29.2?cm3 in 5 patients and decreased by an average of 41.6?cm3 in 6 patien ts. Conclusions 18F-deoxyglucose-positron emission tomography, which can improve target definition between benign and malignant lesions in the lung, is proved t o be more sensitive and specific in detecting mediastinal lymph node involvement . FDG PET may provide accurate target definition and improve the local control.
