Arterial input function
Updates to Article Attributes
Body
was changed:
Arterial input function (AIF) is the concentration of the contrast medium over time in an artery or tissue of interest. In cerebral perfusion imaging is possible to obtain cerebral blood flow (CBF), cerebral blood volume (CBV), mean transitmeasured over time (MTT) and time to transit (Tmax) by deconvolution of AIF time-signal curves.
