An image of rCBF is generated by dividing the images of vascular volume and of intracerebral mean transit time obtained by an angio-CT sequence. This image is comparable to that obtained by Xe-CT as far as the distribution of rCBF is concerned. On quantitative grounds however, it shows larger rCBF values due to the valorization of high flow compartments corresponding to non-nutritional vessels.
