Whole
heart 3D T1-weighted TSE images were acquired with 3T MR imager and
32-channel cardiac coils in 10 patients with Kawasaki disease who had coronary artery aneurysms
and 5 patients with coronary artery disease (CAD). Hyperintense coronary
plaque (HIP) was observed in 5 of 10 patients with Kawasaki disease and 4 of 5 CAD patients.
On MDCT and IVUS, HIP corresponded to thrombus along the vessel wall or
positive remodeling plaque with ultrasound attenuation. 3T T1-weighted coronary plaque MRI allows
for noninvasive screening of HIP in the entire coronary artery tree with an
averaged imaging time of < 10 minutes.
