Vessel wall ADC map generated from six b-values images (0–1000 s/mm2). a B-value images along a certain gradient direction perpendicular to the slice direction (white headless arrow). b ADC map generated from the six b-value images illustrating a signal enhancement along and a signal drop perpendicular to the direction of the applied gradient direction. c Histogram distribution of ADC map indicating two populations of ADC values. d Result of signal simulation using equation S(b) = S 0 e − bD and found ADC populations (green line 2.11 and blue line 1.27e-3 mm2/s). Red vertical lines indicate the final set of selected b-values and black dashed vertical line the maximum difference of the found ADC pool
