Comparison of normal dose iodine derived mean transit time (MTT) map (a) with simulated reduced dose dynamic perfusion acquisition (b). c differential image of normal and reduced dose measurements. d Receiver operating characteristic analysis for classification characterisation of stenotic regions using the reduced dose data. Deviations within the MTT map of the ischaemic and nonischaemic regions increase when applying the contrast agent kinetic model to the reduced number of time points. Nevertheless, a differentiation is achievable using the reduced dose with an area under the curve of 0.96
