Average quantification bias due to perfusion changes. Changes with constant R1 are shown on the left, and with variable R1 on the right. Subject diagnosis is shown by data point shape and tracer influx rate (K1) changes by color. a, b show the bias for Reference Logan DVR on the uninterrupted TAC (TAC120), c, d show the bias for Reference Logan DVR on the dual-time-window TAC with 60-min break (TACDTW60), and e, f show the bias for SUVR90
