3D dark-blood MRI techniques have shown great potential
in coronary plaque burden assessment. However,
substantial variability in quantification could result
from superficial calcification that often mimics part of
lumen because of its low signal. Recent work shows that
gray-blood contrast can help separate superficial
calcification from lumen. Thus, the purpose of this work
was to develop a 3D coronary dark-blood interleaved with
gray-blood (cDIG) MRI technique to improve the
visualization and quantification of coronary plaque. In
vivo experiment results demonstrated that dual contrasts
were simultaneously acquired using the proposed method
without compromising dark-blood contrast and scan time.
