Journal ArticleDOI
Motion correction for myocardial T1 mapping using image registration with synthetic image estimation.
Hui Xue,Saurabh Shah,Andreas Greiser,Christoph Guetter,Arne Littmann,Marie-Pierre Jolly,Andrew E. Arai,Sven Zuehlsdorff,Jens Guehring,Peter Kellman +9 more
TL;DR: Validation on a consecutive patient data cohort shows that this strategy can perform robust nonrigid registration to align inversion recovery images experiencing significant motion and lead to suppression of motion induced artifacts in the T1 map.
Journal ArticleDOI
Spiral Phyllotaxis: The Natural Way to Construct a 3D Radial Trajectory in MRI
TL;DR: An innovative 3D radial trajectory based on a natural spiral phyllotaxis pattern is introduced, which features optimized interleaving properties that facilitate simple density compensation and high reduction of eddy current artifacts and overall improvement in image quality.
Journal ArticleDOI
Respiratory self-navigation for whole-heart bright-blood coronary MRI: methods for robust isolation and automatic segmentation of the blood pool.
TL;DR: An innovative method based on a targeted combination of the output signals of an anterior phased‐array surface coil is implemented to efficiently suppress additional bright signal from the chest wall, spine, arms, and liver and an algorithm for the automatic segmentation of the blood pool is proposed.
Journal ArticleDOI
Respiratory Self-navigated Postcontrast Whole-Heart Coronary MR Angiography: Initial Experience in Patients
Davide Piccini,Pierre Monney,Christophe Sierro,Simone Coppo,Gabriele Bonanno,Ruud B. van Heeswijk,Jerome Chaptinel,Gabriella Vincenti,Jonathan De Blois,Simon C. Koestner,Tobias Rutz,Arne Littmann,Michael Zenge,Juerg Schwitter,Matthias Stuber +14 more
TL;DR: The self-navigated coronary MR angiography sequence shows promise for coronary imaging, however, technical improvements are needed to improve image quality, especially in the more distal coronary segments.
Journal ArticleDOI
Acquisition-Related Morphological Variability in Structural MRI
TL;DR: Imperfections in the MRI data-acquisition process in combination with practical limitations in patient repositioning can substantially confound studies of subtle morphological changes.
