PARAMETRIC IMAGING WITHOUT PRE-SCAN BLOOD INPUT FUNCTION

Abstract: systems and methods include acquisition of positron emission tomography (pet) data of a volume comprising blood and tissue, determination, from the acquired pet data, of a blood input function (bif) from a time at which non-metabolized radionuclide tracer within the volume has reached a steady state between the blood and the tissue, and determination of parametric images based on the acquired pet data, the determined bif and a parametric model which does not include bif values prior to the time.
