Researchers have developed RADIANT-PET, a novel framework for improving lesion segmentation in PET/CT scans for oncology. This system integrates a voxel-level segmentation model with a large language model (LLM) for lesion-level adjudication. Candidate uptake regions are described textually and then classified by an LLM as either a true lesion or a false positive, with the option to incorporate radiology reports for enhanced accuracy. The LLM's reasoning capabilities are further refined through reinforcement learning using Group Relative Policy Optimization, aiming to improve lesion classification and anatomical site assignment.
