Technical feasibility of AI-based longitudinal multi-organ volumetry on low-dose PET/CT over 13 years.
PURPOSE This study aimed to (i) compare TotalSegmentator Fast and Normal inference modes on low-dose PET/CT, (ii) evaluate whether CT denoising improves segmentation longitudinal consistency, and (iii) examine whether the selected pipeline can capture long-term within-participant volumetric trends over approximately 13...
