AI-Driven Multi-Organ Segmentation (MOOSE) for kinetic analysis in dynamic PET. This figure demonstrates an AI-assisted segmentation approach applied to dynamic PET/CT imaging for the extraction of time-activity curves (TACs) across multiple organs. Central is a PET image overlaid with segmented organs; surrounding it are graphs depicting TACs for the brain, left ventricle, aorta, lung, liver, pancreas, spleen, and skeleton. These curves are derived from dynamic PET scans post-segmentation and are instrumental in streamlining kinetic modeling and facilitating absolute quantification of tracer uptake, thus enhancing the precision of metabolic studies
