Unexpected Giant Right Coronary Artery Aneurysm Diagnosed by Computed Tomography Angiography in the Emergency Department

Journal of Clinical Ultrasound, Volume 54, Issue 2, Page 509-515, February 2026.
3D Volume Rendering coronary CTA reconstruction showing a giant thrombosed aneurysm of the proximal right coronary artery ABSTRACT Giant coronary artery aneurysms (GCAA) are usually defined as diameter > 8 mm or > 400% of the adjacent normal segment; they are very rare (reported prevalence ≈0.02%).

Novel Echocardiographic Index for Risk Stratification of Ventricular Arrhythmias and Mortality Based on Right Ventricular Function

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Patients undergoing ICD implantation with both preprocedural echocardiography and cardiac magnetic resonance (CMR) were retrospectively analyzed to assess right ventricular (RV) function. Echocardiographic RV fractional area change (RVFAC) and the contraction pressure index (CPI), as well as CMR‐derived RV ejection fraction (RVEF), predicted ...

Optimized reconstruction of undersampled Dixon sequences using new memory‐efficient unrolled deep neural networks: HalfVarNet and HalfDIRCN

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1189-1204, February 2026.
Abstract Purpose Fat fraction (FF) quantification in individual muscles using quantitative MRI is of major importance for monitoring disease progression and assessing disease severity in neuromuscular diseases. Undersampling of MRI acquisitions is commonly used to reduce scanning time. The present paper introduces novel unrolled neural networks for the

Transcranial Doppler ultrasound validation of BOLD‐fMRI cerebral blood flow relationship

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 939-950, February 2026.
Abstract Purpose A precise understanding of the interplay between cerebral blood flow (CBF) and blood oxygen level‐dependent (BOLD) fMRI signals is essential for advancing cerebrovascular research. Although calibrated BOLD approaches often rely on arterial spin labelling (ASL) to estimate CBF, alternative validation using transcranial Doppler ...
