Zusammenfassung
Purpose: 1) To evaluate the feasibility, image quality and accuracy of coronary MRA at 3.0 T in patients with suspected coronary artery disease and 2) to compare these results with coronary MRA data acquired at 1.5 T. Materials and Methods: 18 patients with suspected coronary artery disease, who were scheduled to undergo elective x-ray coronary angiography were included. For coronary MRA at 3.0 T and 1.5 T, a Vector- ECG gated three-dimensional segmented k-space gradient echo imaging sequence was combined with real time respiratory navigator gating and tracking. Signal-to-noise ratios (SNR), contrast-to-noise ra…
