Automated Pericardial Fat Quantification from Coronary Magnetic Resonance Angiography
Pericardial fat volume (PFV) is emerging as an important parameter for cardiovascular risk stratification. We propose a hybrid multi-atlas and graph-based segmentation approach for automated PFV quantification from water/fat-resolved whole-heart “needlefree” non-contrast coronary magnetic resonance angiography (MRA). We validated the quantification results on 6 subjects and compared them with m...

Pericardial fat volume (PFV) is emerging as an important parameter for cardiovascular risk stratification. We propose a hybrid approach for automated PFV quantification from water/fat-resolved whole-heart noncontrast coronary magnetic resonance angiography (MRA). Ten coronary MRA datasets were acquired. Image reconstruction and phase-based water-fat separation were conducted offline. Our propos...
متن کاملCoronary magnetic resonance angiography.
Coronary magnetic resonance angiography (MRA) is a powerful noninvasive technique with high soft-tissue contrast for the visualization of the coronary anatomy without X-ray exposure. Due to the small dimensions and tortuous nature of the coronary arteries, a high spatial resolution and sufficient volumetric coverage have to be obtained. However, this necessitates scanning times that are typical...
متن کاملFat-suppressed breath-hold magnetic resonance coronary angiography.
BACKGROUND The ability to image the coronary arteries noninvasively would represent an advance in patient care. We have developed a magnetic resonance (MR) angiographic technique that allows the acquisition of complete images of coronary flow within a single breath-hold. By this method, the feasibility of noninvasive MR coronary angiography was evaluated in 25 subjects, including 19 healthy adu...
