Article Synopsis
- The study aims to evaluate how texture features from 18 F-FDG PET/CT imaging can predict lymph node involvement in cervical cancer, focusing on intratumor heterogeneity.
- A total of 101 cervical cancer patients were analyzed, extracting both conventional PET indices and 35 radiomic features to differentiate between patients with and without lymph node involvement.
- The findings indicate that while PET texture features showed some promise, they did not surpass the predictive performance of traditional PET metrics, suggesting a moderate utility in clinical settings.
In localisation of radiotherapy treatment field, the oncologist is present at the simulator to approve treatment details produced by the therapist. Problems may arise if the oncologist is not available and the patient requires urgent treatment. The development of a tele-localisation system is a potential solution, where the oncologist uses a personal digital assistant (PDA) to localise the treatment field on the image sent from the simulator through wireless communication and returns the information to the therapist after his or her approval.

Eight NPC patients (Stages I-IV), who had completed RA treatment, were selected for this study. Computed tomography data sets were re-planned using 7-fields fixed beam IMRT.
