Metabolic response of pelvic and para-aortic lymph nodes during radiotherapy for carcinoma of the uterine cervix: using positron emission tomography/computed tomography.

Abstract

We suggest that the PET/CT can be a useful tool for the evaluation of the interim response of the LNs and aid in selecting patients that need further treatment. The results showed a significant correlation between the metabolic and volumetric responses during RT, although the anatomical changes of LNs would not always represent the metabolic status.
