Fig. 3From: Using a respiratory navigator significantly reduces variability when quantifying left ventricular torsion with cardiovascular magnetic resonanceRespiratory navigator gating. (Left) The diaphragm position is at the high-contrast interface between the lung (dark) and the liver (bright). (Right) Image of a measured diaphragm position over time for separate breath-holds. For this subject, there was an 11Â mm difference in end-expiratory position between breath-hold 1 and 10Back to article page
