Input functions extraction from gated 18F-FDG PET images

Abstract

Derivation of the plasma time-activity curve in small animal positron emission tomography (PET) studies is a challenging task. Non-invasive input functions (IF) estimation in cardiac imaging usually involves drawing a region of interest (ROI) within the left ventricle (LV) of the heart. The small size of the LV relative to the resolution of the small-animal… (More)
