Paper Published: Scan-Rescan Reproducibility of Carotid Geometry

Congratulations to PhD student Payam Bijari, whose first BSL paper, "Scan-rescan reproducibility of carotid bifurcation geometry from routine contrast-enhanced MR angiography", was recently published in the Journal of Magnetic Resonance Imaging.

As suggested by the figure, this paper demonstrates that lumen geometry can be rapidly and reliably segmented from not-always-optimal MR angiograms, in our case from 60 participants in the ARIC Carotid MRI study, each scanned twice on separate occasions. This now sets the stage for our analysis of the full cohort, which seeks to identify whether the geometry of the carotid bifurcation can be considered a "missing" local risk factor for atherosclerosis.
