Abstract Objective: To explore the location value of PET-CT in 125I seeds permanent braehytherapy treatment for non-small cell lung carcinoma(NSCLC) patients. Methods: From 26 patients with NSCLC underwent whole body PET-CT scans, PET-CT and CT images were input into the treatment plan system(TPS), radiotheapy dose were calculated, compared with gross tumor volume and the numbers of 125I seeds. Results: The gross tumor volume, the mean number of seeds were (51.03±16.02)cm3, 43.88±12.30, in PET-CT group and (58.10±19.11)cm3, 49.46±14.74 respectively, in CT group, gross tumor volume of PET-CT group reduced 12.17%, number of seeds reduced 11.28%(P<0.001). Conclusion: PET-CT is more accurate than CT alone in the assessment of the radiation target volume for NSCLC patients.
