Journal ArticleDOI
Coronary Magnetic Resonance Angiography for the Detection of Coronary Stenoses
W. Yong Kim,W. Yong Kim,Peter G. Danias,Matthias Stuber,Scott D. Flamm,Sven Plein,Eike Nagel,Susan E. Langerak,Oliver M. Weber,Erik Morre Pedersen,Matthias Schmidt,René M. Botnar,Warren J. Manning,Warren J. Manning +13 more
TL;DR: Among patients referred for their first x-ray coronary angiogram, three-dimensional coronary magnetic resonance angiography allows for the accurate detection of coronary artery disease of the proximal and middle segments.
Journal ArticleDOI
Improved Coronary Artery Definition With T2-Weighted, Free-Breathing, Three-Dimensional Coronary MRA
TL;DR: Free-breathing, T2prep, 3D coronary MRA with a shorter acquisition window resulted in improved CNR and better coronary artery definition, allowing the assessment of coronary disease.
Journal ArticleDOI
Double-oblique free-breathing high resolution three-dimensional coronary magnetic resonance angiography
Matthias Stuber,Matthias Stuber,René M. Botnar,René M. Botnar,Peter G. Danias,Daniel K. Sodickson,Kraig V. Kissinger,Marc Van Cauteren,Jan De Becker,Warren J. Manning +9 more
TL;DR: Double-oblique submillimeter free-breathing coronary MRA allows depiction of extensive parts of the native coronary arteries and has the potential to be applied in broader prospective multicenter studies where coronary Mra is compared with X-ray angiography.
Journal ArticleDOI
Noninvasive Coronary Vessel Wall and Plaque Imaging With Magnetic Resonance Imaging
René M. Botnar,Matthias Stuber,Kraig V. Kissinger,Won Yong Kim,Elmar Spuentrup,Warren J. Manning +5 more
TL;DR: In vivo free-breathing coronary vessel wall and plaque imaging with MR has been successfully implemented in humans and may have potential applications in patients with known or suspected atherosclerotic CAD or for serial evaluation after pharmacological intervention.
Journal ArticleDOI
Detection of pulmonary vein and left atrial scar after catheter ablation with three-dimensional navigator-gated delayed enhancement MR imaging: initial experience.
Dana C. Peters,John V. Wylie,Thomas H. Hauser,Kraig V. Kissinger,René M. Botnar,Vidal Essebag,Mark E. Josephson,Warren J. Manning +7 more
TL;DR: High-spatial-resolution delayed enhancement MR imaging allows noninvasive identification of scar induced by RF ablation following isolation therapy of the PV.
