Carotid bifurcation geometry has been identified implicated as a risk factor for the development of atherosclerotic plaque. Geometrical factors associated with flow propertiesfeatures can be assessed from 3D models derived from either bright blood or black blood MRI. Reproducibility of these geometrical parameters is important for longitudinal studies of risk assessment. While reproducibility of black-blood derived geometry has been previously reported, bright blood reproducibility is unknown. We show that geometric parameters assessed by bright blood MRI are comparable to those derived from black blood MRI.
