Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging
Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 917-937, April 2026.ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Performance Study of a Torsional Wave Sensor and Cervical Tissue Characterization
Sensors, 2017 A novel torsional wave sensor designed to characterize mechanical properties of soft tissues is presented in this work. Elastography is a widely used technique since the 1990s to map tissue stiffness. Moreover, quantitative elastography uses the velocity

Stability Analysis in Magnetic Resonance Elastography II
, 2015 We consider the inverse problem of finding unknown elastic parameters from internal measurements of displacement fields for tissues. In the sequel to Ammari, Waters, Zhang (2015), we use pseudodifferential methods for the problem of recovering the shear ...

Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2356-2369, April 2026.ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

Barriers to Medical Care Are Frequently Reported by Patients With Cirrhosis
Alimentary Pharmacology &Therapeutics, Volume 63, Issue 8, Page 1162-1168, April 2026.In a telephone‐based survey study among > 1000 patients with cirrhosis, the most frequent barriers to care included time to travel to clinic, long wait times for appointments, and difficulty scheduling visits. Several barriers to care significantly differed by study site but were generally consistent across racial and ethnic subgroups.

A new method for shear wave speed estimation in shear wave elastography
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015 Visualization of mechanical properties of tissue can aid in noninvasive pathology diagnosis. Shear wave elastography (SWE) measures the elastic properties of soft tissues by estimation of local shear wave propagation speed. In this paper, a new robust method for estimation of shear wave speed is introduced which has the potential for simplifying ...
