The registration for the images from the multicontrast [TOF, T1-, T2-, PD-weighted, and magnetization-prepared rapid acquisition gradient-echo (MP-RAGE)] and CINE protocols was achieved by using the bifurcation imaged slice (marked 0) as landmark. Note: * denotes lumen of carotid artery and • denotes lumen of jugular vein.
Distensibility (DC) distribution along the carotid bifurcation for the study population. Location indexed as 0 corresponds to the flow divider. The common carotid artery is represented with values lower than 0, whereas the internal carotid artery is represented with values greater than 0.
Interscan reproducibility analysis.
Distensibility (mean ± SD × 10−5/Pa) by vessel segment in 5 healthy and 17 diseased subjects.
Percent change in slice-measured DC per unit change in plaque variable: Location-based analysis.
Correlations of aggregated plaque morphology and composition variables with mean DC.
