SNAP can simultaneously detect lumen stenosis and
intraplaque hemorrhage in a single scan. The accuracy
SNAP lumen measurement relative to clinically used
techniques such as contrast-enhanced MRA (CE-MRA) is not
known. Lumen area measurements from 15 patients scanned
with SNAP and CEMRA were compared. Our results show that
that SNAP provides comparable measurement to CE-MRA for
lumen area indicating that SNAP is a potential
non-contrast alternative to CEMRA for lumen stenosis
assessment.
