Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2505-2515, November 2026.
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2213-2227, November 2026.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.

Mitral Valve Prolapse: Novel Assessment With Real-Time 3D Echocardiography

, 2017
Mitral valve prolapse (MVP) is the most common cause ofmitral regurgitation and the most frequent reason for mitralvalve surgery in Europe. The most traditional methodfor mitral valve evaluation has been two-dimensional (2D)transthoracic echocardiography.

Evaluating Perfusion Quantification for Phase‐Resolved Functional Lung MRI Using Gaussian Filtering

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Current PREFUL perfusion quantification uses a slice‐wise median for the maximal blood exchange fraction ΔS, limiting regional information. Gaussian filtering (σ = 1.5) ΔS in perfusion calculation adds regional information and improves intrascan and interscan repeatability while preserving global and voxel‐wise correlations with DCE‐derived pulmonary ...
