Optimal CTP scan duration and rVOF height at scan completion for reliable CTP lesion estimation

Percentile of patients with reliable CTP lesion volume estimates (n=59) Optimal CTP scan duration (native T0) Optimal CTP scan duration (T0 normalized to 10s) rVOF height
50th 42.3 s 32.7 s 39%
60th 47.6 s 37.2 s 28%
70th 52.4 s 41.0 s 11%
80th 55.9 s 45.9 s 6%
90th 60.7 s 52.6 s 2%
100th 72.9 s 68.9 s 0%

CTP indicates computed tomography perfusion; rVOF: height of the fitted venous output function expressed as a fraction of peak height; T0: bolus arrival time.
