Prospective Comparison of DWI‐Derived Virtual MR Elastography and Conventional MR Elastography in Metabolic Dysfunction‐Associated Steatotic Liver Disease and Healthy Volunteers

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Virtual MR elastography (VMRE) and MRE have been proposed for liver fibrosis staging in metabolic dysfunction‐associated steatotic liver disease (MASLD), but VMRE's diagnostic performance remains debated. Purpose To assess the inter‐visit and inter‐reader reproducibility of fat‐uncorrected and fat‐corrected diffusion‐weighted ...

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
