Evaluation of morphologic characterization of BA plaque (such as plaque area, stenosis rate and percent plaque burden) is significant and may guide treatment decisions in clinical setting. In this study, we employed the maximal lumen narrowing sites as the referenced sites to calculate morphologic parameters. This study aims to compare the Referenced and Self-referenced measurement method methods in assessing basilar atherosclerotic plaque employing dark blood HRMRI at 3 Tesla. The present study found Self-referenced method is more convenient and even better for evaluating BA plaque.
