Comparison of standard uptake value (SUV) temporal trends (left) and %ID/kg temporal trends (right) in normal prostate (blue) and lesion (red). Shown is the mean uptake for prostate and lesion at 5 min intervals, calculated as the uptake over a sliding 10-min window centered over each timepoint. Lesion Z-scores (right) are calculated for SUV and %ID/kg using the difference of lesion signal and reference prostate signal, relative to the standard deviation in reference prostate using patient population averages at each timepoint. Error bars represent 95% confidence intervals of the mean. Statistical tests convey the results of a patient-wise paired t test at each timepoint. p < 0.01 is indicated by **, p < 0.001 is indicated by ***, and p < 0.0001 is indicated by ****
