Journal ArticleDOI
Experimental validation of an automated edge‐detection method for a simultaneous determination of the endocardial and epicardial borders in short‐axis cardiac MR images: Application in normal volunteers
Alain Furber,Philippe Balzer,Christine Cavaro-Menard,Anne Croue,Eric Da Costa,Franck Lethimonnier,Philippe Geslin,A. Tadei,Pierre Jallet,Jean-Jacques Le Jeune +9 more
TL;DR: Several techniques of image segmentation were put together to provide a reliable assessment of the left ventricular mass with short‐axis cardiac MR images based on region growing, gradient detection, and adaptive thresholding to allow the application of this method to the quantification of theleft ventricular function and mass in clinical practice.
Journal ArticleDOI
Regional assessment of wall curvature and wall stress in left ventricle with magnetic resonance imaging.
Philippe Balzer,Alain Furber,Stéphane Delépine,F. Rouleau,Franck Lethimonnier,Olivier Morel,A. Tadei,Pierre Jallet,Philippe Geslin,Jean-Jacques Le Jeune +9 more
TL;DR: Long-axis studies proved to be insufficient for determining the regional variations of left ventricular wall stress and for providing normal reference values for the location of abnormal regions in patients and the integration of the short-axis and long-axis wall curvatures for determining peak systolic wall stress is described.
Journal ArticleDOI
Three-dimensional coronary artery MR imaging using prospective real-time respiratory navigator and linear phase shift processing: comparison with conventional coronary angiography.
Franck Lethimonnier,Alain Furber,Oliver Morel,Philippe Geslin,Philippe L’Hoste,A. Tadei,Pierre Jallet,Christine Caron-Poitreau,Jean-Jacques Le Jeune +8 more
TL;DR: The ability to image correctly coronary arteries and to identify proximal stenoses, but image quality need to be improved for an efficiency detection of coronary artery stenoses in clinical practice is shown.
Journal ArticleDOI
Global left ventricular cardiac function: comparison between magnetic resonance imaging, radionuclide angiography, and contrast angiography.
Franck Lethimonnier,Alain Furber,Philippe Balzer,Olivier Morel,F. Rouleau,Stéphane Delépine,P. Pezard,P. Geslin,Pierre Jallet,J.-J. Le Jeune +9 more
TL;DR: Cardiac MRI is a fast and accurate technique for estimation of LV volumes, EF, and mass using fast techniques for acquisition and postprocessing.
Journal ArticleDOI
Interventional MR imaging at 1.5 T: quantification of sound exposure
TL;DR: Sound pressure levels during interventional magnetic resonance (MR) imaging may create an occupational hazard for the interventional radiologist (ie, the potential risk of hearing impairment), so hearing protection is recommended.
