The ability to characterize atheroma components is
central to assessing the status of vessel disease, and
its progression and response to intervention. High-field
intravascular MRI (IVMRI) offers the potential for
assessing T
1
, T
2
, proton density
and lipid burden in healthy and diseased vessels at a
resolution approaching 100m. Here, results from
multi-parametric, 200m-resolution intravascular IVMRI
employing a novel Tri-Flip-Angle method are presented.
T
1
, T
2
and
proton density are mapped with B
1
-self-correction
in only four acquisitions, while the lipid pool is
imaged by Dixon (or selective saturation) techniques in
human iliac artery specimens.
