Retrieving the accurate time-tracer activity concentration curve of the blood (arterial input function) is mandatory for performing bio kinetic model analysis of dynamic PET data. Especially in small rodents, gathering the input function remains an active area of research as no generally applicable solution was found so far. While surgically catheterizing blood vessels of rodents is possible, it is labour intensive and time resolution of blood sampling is restricted due to the limited amount of overall blood and the procedure of blood withdrawal itself.
