Résumé
This study aims to investigate the feasibility of a "real-time" estimate of the optimal CT perfusion (CTP) acquisition time (T The arterial input function, the venous output function (VOF), and the time-attenuation curves of ischemic core and ischemic penumbra of 51 patients with acute ischemic stroke in anterior circulation were obtained. The curves were analyzed to determine for each patient the T We found a strong linear correlation between each time parameter derived from VOF curve and T The linear correlation between T

BACKGROUND AND PURPOSE
This study aims to investigate the feasibility of a "real-time" estimate of the optimal CT perfusion (CTP) acquisition time (T
METHODS
The arterial input function, the venous output function (VOF), and the time-attenuation curves of ischemic core and ischemic penumbra of 51 patients with acute ischemic stroke in anterior circulation were obtained. The curves were analyzed to determine for each patient the T
RESULTS
We found a strong linear correlation between each time parameter derived from VOF curve and T
CONCLUSIONS
The linear correlation between T
