Venous ROI variability was associated with CBF/CBV differences; hypothesis-generating for standardized vascular input functions in CT perfusion.
Does the selection of vascular input function curves and ROI locations influence mean perfusion parameter values and SNR in CT perfusion studies?
Optimal selection of regions of interest for vascular input functions is crucial to limit variability and improve the quality of CT perfusion images.
