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 ...

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

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,
