Ultrasound and CMR images. A. B-mode ultrasound of the common carotid artery demonstrating plaque. Automated software detection is used to measure mean posterior IMT. B. Oblique sagittal spin echo of the carotid artery showing the reference flow divider (white arrow). C. Multicontrast CMR T1/T2/proton density spin echo and time of flight gradient echo images of the same axial slice. Luminal/adventitial borders are outlined to measure plaque area/volume.
