Based on discrete mathematical morphology, we propose a new automated and fast procedure to segment the left ventricular my-ocardium in 4D (3D+t) cine-MRI sequences. Thanks to the comparison with manual segmentation performed by two cardiologists, we demonstrate the accuracy of the proposed method. The relevance of the ejection fraction and myocardium mass(More)
BACKGROUND Early detection of diastolic dysfunction is crucial for patients with incipient heart failure. Although this evaluation could be performed from phase-contrast (PC) cardiovascular magnetic resonance (CMR) data, its usefulness in clinical routine is not yet established, mainly because the interpretation of such data remains mostly based on manual(More)
Early detection of diastolic dysfunction is crucial for patients with incipient heart failure. Our goal was to develop a robust process to automatically estimate diastolic parameters from phase-contrast cardiovascular magnetic resonance (PC-CMR) data and to test their ability to characterize left ventricular (LV) dysfunction. We studied 53 subjects (35(More)
BACKGROUND Despite marked benefits in many heart failure patients, a considerable proportion of patients treated with cardiac resynchronization therapy (CRT) fail to respond appropriately. Recently, a "U-shaped" (type II) wall motion pattern identified by cardiovascular magnetic resonance (CMR) has been associated with improved CRT response compared to a(More)
