In vitro characterization of hemodynamics in bicuspid aortic valves: The impact of valve and ascending aortic morphologies

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.

Breijo Electrocardiographic Pattern

Archivo Médico de Camagüey, 2018
Background: the decrease in cardiac electrical systole (short intervals of PR and QTc in the same electrocardiogram, also known as "Breijo electrocardiographic pattern") is increasingly studied.

Online Spatiotemporally Constrained Reconstruction for Real‐Time Interactive MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a low‐latency dynamic MRI reconstruction that provides better spatial and temporal fidelity than contemporary online reconstruction, for localization. Methods We utilize online spatiotemporally constrained reconstruction (STCR) using a computationally efficient augmented Lagrangian solution and a limited number of iterations

Multi‐Frame Image Registration for Automated Ventricular Function Assessment in Single Breath‐Hold Cine MRI Using Limited Labels

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aims to develop an automated framework for operator‐independent assessment of cardiac ventricular function from highly accelerated images. Methods We introduce a deep learning framework that generates reliable ventricular volumetric parameters and strain measures from fully sampled and retrospectively accelerated MR images ...
