چکیده

Background Cardiac and respiratory motion artifacts are major challenges to whole-heart coronary MRA. The conventional motion suppression strategies often involve prospective gating based on motion surrogates, e.g. ECG and navigator, which complicates scan setup and prolongs scan time significantly. To address these limitations, an ECG and navigator-free 4D whole-heart coronary MRA technique was recently proposed, providing both cardiac function and coronary artery assessment from a single measurement [1]. In this work, we evaluate the 4D technique by comparing it against conventional cine and coronary MRA protocols.

ECG/Navigator-Free 4D Whole-Heart Coronary MRA with Simultaneous Visualization of Cardiac Function and Anatomy

Purpose: Cardiac and respiratory motion artifacts are major challenges in cardiac MRI, and are conventionally suppressed by prospective ECG and diaphragm navigator gating, respectively. However, these approaches require time-consuming setup and prolonged acquisition times, and are susceptible to variations of heart rate or respiratory pattern. Further, they can become unreliable at higher field...

Assessment of coronary artery disease using 3.0T magnetic resonance coronary angiography: a national multicenter trial

Background 3.0T contrast enhanced whole-heart coronary magnetic resonance angiography (MRA) is a promising method for noninvasive, radiation-free detection and exclusion of obstructive coronary artery disease (CAD); however, the accuracy of this approach has not been determined in a multicenter trial. Methods An ECG-triggered, navigator-gated, inversion-recovery prepared, segmented gradient-ech...

Dynamic self-navigated 3D whole-heart radial coronary MRA with retrospective acquisition window selection

Background Navigator gated coronary MRA is highly time inefficient as the data collection duty cycle (DC) is only 2% [1]. Here, we report a new, dynamic self-navigated coronary MRA technique with isotropic spatial resolution that a) further improves DC by continuously acquiring image data without ECG triggering and that b) enables retrospective, flexible, and individual selection of the acquisi...

3T Coronary MRA using 3D Multi-interleaved Multi-echo Acquisition and VARPRO Fat-water Separation

Introduction: Coronary MR Angiography is a valuable tool for non-invasive assessment of coronary arteries. Presently, contrastenhanced, fat-saturated, ECG-triggered and navigator-gated 3D spoiled gradient-echo sequence is employed for whole-heart Coronary MRA at 3T. However, large static field variations at 3T frequently result in non-uniform fat-suppression over the field-of-view (FOV), obscur...

3.0T whole-heart coronary magnetic resonance angiography performed with 32-channel cardiac coils: a single-center experience.

BACKGROUND Whole-heart coronary magnetic resonance angiography (MRA) is a promising method for noninvasive, radiation-free detection and exclusion of obstructive coronary artery disease; however, the required imaging time and robustness of the technique are not yet satisfactory. We evaluated the value of whole-heart coronary MRA at 3.0T using a 32-channel cardiac coil, which reduces image-acqui...
