Effect of the Arterial Input Function on the Measured Perfusion Values and Infarct Volumetric in Acute Cerebral Ischemia Evaluated by Perfusion Computed Tomography

Abstract

The AIF selection in the ACA as well as in the ipsilateral (to the hypoperfused area) or contralateral branches of the MCA has no statistically significant impact on the calculation of the CBF, CBV values, and the volume estimation of the ischemic region in the acute stroke patients.
