Females exhibit greater cardiac volume reductions with expiratory muscle loading during submaximal exercise compared to males

The Journal of Physiology, EarlyView.
Abstract figure legend Intrathoracic pressure (ITP) manipulation during submaximal exercise reveals load‐ and sex‐specific cardiac volume responses. Inspiratory loading increased oesophageal pressure swings and the work of breathing (Wb) but did not alter stroke volume (SV) or ventricular volumes in males or females.

Jointly Learned 3D Non‐Cartesian Sampling With Wave Encoding and Reconstruction for Neurovascular Phase Contrast MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2554-2567, May 2026.
ABSTRACT Purpose To develop accelerated 3D phase contrast (PC) MRI using jointly learned wave encoding and reconstruction. Methods Pseudo‐fully sampled neurovascular 4D flow data (N = 40) and a simulation framework were used to learn phase encoding locations, wave readout parameters, and model‐based reconstruction network (MoDL) for a rapid 3D PC scan (

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2568-2579, May 2026.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.
