Researchers have developed ReMAP-PET, a new framework designed to better interpret Positron Emission Tomography (PET) scans by focusing on regional metabolic alignment semantics. Unlike existing models that treat PET scans as generic volumetric data, ReMAP-PET uses a partially-tuned MedicalNet 3D ResNet-50, supervised with brain regional standardized uptake value ratio (SUVR) profiles. This approach allows the model to learn the specific metabolic information within PET scans, achieving a 0.070 SUVR MAE and 77.8% PET SUVR Recall@1 on 1015 samples. The framework also integrates with clinical language models like BioClinicalBERT for end-to-end PET-to-report generation, demonstrating its potential for interpretable and language-compatible metabolic understanding.
