From: Development of a dynamic myocardial perfusion phantom model for tracer kinetic measurements
Time activity curves derived from phantom measurements. The mean arterial input function (AIF) and tissue functions (TRFs) of n measurements were plotted together with their standard deviation (SD). TRF analysis distinguished between myocardial segment flow settings of 40 and 80 mL/min. The AUCs within the indicated blue regions served as input for myocardial blood flow estimation. The dashed lines in the TRFs suggest how the curves would look when corrected for radiotracer recirculation
