PWV calculation using 2D CINE PC CMR and black-blood CMR. a Black-blood image and curved path ∆x tracked between the two slices. b Velocity images acquired perpendicular to the common carotid artery (slice 1) and the internal carotid artery (slice 2). c The transit time was calculated from the two flow curves using the CC (left) and FF (right) method. Details on the CC and FF methods are shown in Additional file 1: Figure S1. CCA=common carotid artery; ICA=internal carotid artery
