Does a diaphragmatic navigator improve vessel delineation compared to a left ventricular navigator during three-dimensional free-breathing coronary magnetic resonance angiography in healthy volunteers?
In 3D free-breathing coronary MRA, placing the real-time navigator at the right hemidiaphragm provides superior vessel delineation compared to the left ventricle.
Three-dimensional free-breathing coronary magnetic resonance angiography was performed in eight healthy volunteers with use of real-time navigator technology. Images acquired with the navigator localized at the right hemidiaphragm and at the left ventricle were objectively compared. The diaphragmatic navigator was found to be superior for vessel delineation of middle to distal portions of the coronary arteries.
