<sup>31</sup>P-MRS of the Human Heart at 7 T With an Integrated Whole-Body <sup>31</sup>P Radiofrequency Transmit Coil. [PDF]
NMR BiomedWe demonstrate the use of an integrated whole‐body phosphorus‐31 (31P) radiofrequency transmit coil for 31P‐MR spectroscopic imaging of the human heart at 7 T. Intersession measurement repeatability of the mid‐septal myocardial phosphocreatine (PCr) over adenosine triphosphate (ATP) concentration ratio in normal volunteers was 17.7%.

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 ...

Low-field cine magnetic resonance imaging
The British Journal of Radiology, 1990 The spin warp technique (Edelstein et al, 1980) is now the most commonly used method of image formation for nuclear magnetic resonance (NMR) studies. This technique combines frequency and phase encoding of positional information onto the signal to allow subsequent image reconstruction.

A novel method for estimating myocardial strain: assessment of deformation tracking against reference magnetic resonance methods in healthy volunteers [PDF]
, 2016 We developed a novel method for tracking myocardial deformation using cardiac magnetic resonance (CMR) cine imaging. We hypothesised that circumferential strain using deformation-tracking has comparable diagnostic performance to a validated method ...

Tile-net for undersampled cardiovascular CINE magnetic resonance imaging
Magnetic Resonance Imaging, 2021 We propose the "Tile-net" method based on dividing an image into smaller tiles. Using the tile as the input to the neural network, the network is simplified substantially. The Tile-net learns at a much faster rate than the networks without tiling. The training and reconstruction times for the Tile-net are reduced by 40% and 33%, respectively compared ...

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