Simplified protocol for whole‐body Patlak parametric imaging with ¹⁸F‐FDG PET/CT: Feasibility and error analysis

Purpose Parametric imaging using the Patlak model has been shown to provide improved lesion detectability and specificity. The Patlak model requires both tissue time–activity curves (TACs) after equilibrium and knowledge of the input function from the start of injection. Therefore, the conventional dynamic scanning protocol typically starts from the radiotracer injection all the way to equilibrium. In this paper, we propose the use of hybrid...
