Journal of Cardiovascular Magnetic Resonance ® , 3(4), 331–338 (2001) Scan Reproducibility of Magnetic Resonance Imaging Assessment of Aortic Atherosclerosis Burden

Subclinical atherosclerosis precedes the onset of clinical disease by many years. Noninvasive magnetic resonance imaging (MRI) offers the opportunity to visualize and quantify atherosclerotic plaque. However, the reproducibility of MRI measurements of abdominal and thoracic aortic atherosclerosis has not been reported. Electrocardiogram-gated, T2-weighted, turbo spin echo MRI of the descending thoracic and abdominal aorta was performed on 16 subjects, comprising 10 subjects with multivessel coronary artery disease (CAD) and 6 subjects without angiographic CAD. Three identical MRIs were performed on each subject, with subject repositioning between the second and third scans. Aortic anatomic and plaque measurements were performed in a blinded fashion. Fourteen subjects (88%) had MRI evidence of atherosclerotic plaque on at least one image. Slice plaque burden, plaque area, Address correspondence and reprint requests to Warren J. Manning

Coronary MR Imaging: Effect of Timing and Dose of Isosorbide Dinitrate Administration1

Sublingual isosorbide dinitrate improves three-dimensional coronary MR imaging signal-to-noise ratios by 20% for targeted acquisitions and by 10% for whole-heart acquisitions
