Figure 6. Variable Imaging Start Time Reduces Predictive Power.

Figure 6.

If a subject is imaged later than the peak induction of cell death, the diagnostic potential dramatically decreases. While longer integration time does capture the longer tails of the induced apoptosis, a fixed early imaging time is critical to enable AUROC > 0.85.
