Comparison of Amplitude‐ and Amplitude‐Frequency‐Modulated Pulses for Outer Volume Suppression in Cardiac MRI: Application to Myocardial T2 Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2240-2252, November 2026.
ABSTRACT Purpose To evaluate single‐ and dual‐band pulse modules for suppressing extra‐cardiac signal in cardiac MRI, and test their applicability for time‐efficient imaging with reduced FOV in myocardial T2 mapping at 3 T. Methods Outer Volume Suppression (OVS) was implemented using two regional saturation slabs, along the phase‐encoding direction ...

Diagnostic Performance of Treadmill Exercise Cardiac Magnetic Resonance: The Prospective, Multicenter Exercise CMR's Accuracy for Cardiovascular Stress Testing (EXACT) Trial

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundStress cardiac magnetic resonance (CMR) has typically involved pharmacologic agents. Treadmill CMR has shown utility in single‐center studies but has not undergone multicenter evaluation.

Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 996-1008, October 2026.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Multifrequency Magnetic Resonance Elastography of the Abdominal Aortic Wall: Segmental, Positional and Flow Effects

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
In vivo abdominal aortic wall–specific MRE enables reproducible wall stiffness mapping while minimizing the intraluminal signal interference, revealing segment‐ and posture‐dependent stiffness patterns that complement morphology and flow measures for clinical evaluation of abdominal aortic wall health.
