Multicontrast MRI is currently used to identify
high-risk atherosclerotic plaque components. We propose
a dual contrast vessel wall MRI sequence to identify
four major high-risk features: plaque burden, stenosis,
intraplaque hemorrhage and juxtaluminal calcification by
extending the phase-sensitive reconstruction of a
recently proposed vessel wall MRI sequence (SNAP) to
include a proton density black-blood weighting. We
demonstrate that combined review of bright-blood,
gray-blood and black-blood images obtained from a single
five minute acquisition can identify high-risk plaque in
patients with atherosclerotic carotid plaque.
