From: The effect of high count rates on cardiac perfusion quantification in a simultaneous PET-MR system using a cardiac perfusion phantom

Fig. 5

Time-activity curves resulting from image analysis with increasing activity administrations to the phantom. Top: C A(PET), and bottom: C M(PET), showing input and washout of the radiotracer. C A(PET) for 804 and 997 MBq injected activities do not increase at the same rate as the myocardial TAC suggesting the reconstructed images are affected by count losses
