چکیده
T. D. Nguyen, A. Nuval, Y. Wang University of Pittsburgh Medical Center, Pittsburgh, PA, United States SYNOPSIS Cardiac fat navigator detects coronary motion directly by exciting and sampling the epicardial fat that surrounds the proximal coronary arteries. The present study demonstrates that motion detected by the cardiac fat navigator at mid-diastole correlates with motion detected by the diaphragm navigator and that cardiac fat navigator is slightly more effective than the diaphragm navigator for free-breathing navigator gated coronary MRA.

Figure 2 – Reformatted images showing the main coronary arteries of two subjects. Subject 1: 2D Affine + translational motion correction gives superior image quality compared to both 2D translational correction and a gated scan (with ~3x reduction in scan time). Subject 2: 2D motion correction gives similar image quality to the gated scan with ~2x reduction in scan time. Affine correction shows...
متن کاملSimulation Tool for k-Space Reordering in Free-Breathing Navigator-Gated 3D Coronary MRA
In coronary MR angiography (MRA) breathing motion during data acquisition may result in image artifacts. One solution is the use of MR navigators to gate to the respiratory cycle, but the use of narrow gating windows often lead to prolonged/time inefficient scans. Therefore sophisticated k-space reordering techniques 1, 2 have been proposed to reduce motion artifacts in free-breathing navigator...
متن کاملDirect monitoring of coronary artery motion with cardiac fat navigator echoes.
Navigator echoes (NAVs) provide an effective means of monitoring physiological motion in magnetic resonance imaging (MRI). Motion artifacts can be suppressed by adjusting the data acquisition accordingly. The standard pencil-beam NAV has been used to detect diaphragm motion; however, it does not monitor cardiac motion effectively. Here we report a navigator approach that directly measures coron...

INTRODUCTION In this work, a respiratory and cardiac self-gated free-breathing 3D cine SSFP imaging technique is proposed utilizing multiple echo acquisitions to separate water and fat for optimal visualization of the coronary arteries. Multi-echo hybrid radial sampling has been shown to have a high data acquisition efficiency and a high robustness to motion. By frequently acquiring the k-space...
متن کاملBreath-hold imaging of the coronary arteries using quiescent-interval slice-selective (qiss) magnetic resonance angiography - pilot study at 1.5 tesla and 3 tesla
BACKGROUND Coronary magnetic resonance angiography (MRA) is usually obtained with a free-breathing navigator-gated 3D acquisition. Our aim was to develop an alternative breath-hold approach that would allow the coronary arteries to be evaluated in a much shorter time and without risk of degradation by respiratory motion artifacts. For this purpose, we implemented a breath-hold, non-contrast-enh...
