Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
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 ...

Longitudinal 4D Flow MRI‐Derived Wall Shear Stress in Patients With an Abdominal Aortic Aneurysm

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 4D flow MRI‐derived parameters such as wall shear stress (WSS) may improve abdominal aortic aneurysm (AAA) progression prediction. Validation of this biomarker is needed, but longitudinal data are lacking. Purpose Investigate longitudinal WSS changes and associations with AAA morphology. Study Type Prospective.

Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Characteristics of Adult Patients With Atopic Dermatitis Initiating Biologics and Janus Kinase Inhibitors in the CorEvitas Atopic Dermatitis Registry

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Biologics and Janus kinase inhibitors (JAKi) are two advanced systemic treatment options for patients with atopic dermatitis (AD). The decision to initiate one of these therapies is complex and may be driven by many factors.
