Super‐Resolution Cine Image Enhancement for Fetal Cardiac Magnetic Resonance Imaging [PDF]

Journal of Magnetic Resonance Imaging, 2021
BackgroundFetal cardiac magnetic resonance imaging (MRI) improves the diagnosis of congenital heart defects, but is sensitive to fetal motion due to long image acquisition time. This may be overcome with faster image acquisition with low resolution, followed by image enhancement to provide clinically useful images.PurposeTo combine phase‐encoding ...

Fetal cardiac cine magnetic resonance imaging in utero [PDF]

Scientific Reports, 2017
AbstractFast magnetic resonance imaging (MRI) led to the emergence of ‘cine MRI’ techniques, which enable the visualization of the beating heart and the assessment of cardiac morphology and dynamics. However, established cine MRI methods are not suitable for fetal heart imaging in utero, where anatomical structures are considerably smaller and ...

A Technique for Generating Volumetric Cine-Magnetic Resonance Imaging [PDF]

International Journal of Radiation Oncology*Biology*Physics, 2016
The purpose of this study was to develop a techique to generate on-board volumetric cine-magnetic resonance imaging (VC-MRI) using patient prior images, motion modeling, and on-board 2-dimensional cine MRI.One phase of a 4-dimensional MRI acquired during patient simulation is used as patient prior images. Three major respiratory deformation patterns of

Generative MR Multitasking With Complex-Harmonic Cardiac Encoding: Bridging the Gap Between Gated Imaging and Real-Time Imaging. [PDF]

Magn Reson Med
ABSTRACT Purpose To develop a unified image reconstruction framework that bridges real‐time and gated cardiac MRI, including quantitative MRI. Methods We introduce generative multitasking, which learns subject‐ and dataset‐specific implicit neural temporal bases from sequence timings and an interpretable latent space for cardiac and respiratory motion.

Uterine anatomy and function on cine magnetic resonance imaging [PDF]

Reproductive Medicine and Biology, 2016
AbstractThe female reproductive organ undergoes dynamic morphological changes under the influence of hormonal stimuli, and particularly those mediated by estrogen and progesterone. The uterus changes both its morphological appearance and its functional movements in function of these influences.

Sophisticated Study of Time, Frequency and Statistical Analysis for Gradient-Switching-Induced Potentials during MRI

Bioengineering, 2023
Magnetic resonance imaging (MRI) is a standard procedure in medical imaging, on a par with echography and tomodensitometry. In contrast to radiological procedures, no harmful radiation is produced.

A review of heart chamber segmentation for structural and functional analysis using cardiac magnetic resonance imaging [PDF]

, 2016
Cardiovascular magnetic resonance (CMR) has become a key imaging modality in clinical cardiology practice due to its unique capabilities for non-invasive imaging of the cardiac chambers and great vessels. A wide range of CMR sequences have been developed

The Application and Research Progress of Cardiac Magnetic Resonance in the Assessment of Right Ventricular-Pulmonary Arterial Coupling [PDF]

Advanced Ultrasound in Diagnosis and Therapy
Right ventricular-pulmonary arterial coupling refers to the interaction and functional matching between the right ventricle and the pulmonary artery. When the coupling is disrupted, it can lead to a series of cardiovascular diseases, such as pulmonary ...
