Comparison of Retrospective Motion Compensation Techniques for Pulmonary Dynamic Ultrashort Time to Echo MRI in Suspected Idiopathic Pulmonary Fibrosis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Motion can degrade image quality during Ultrashort Time‐to‐Echo (UTE) pulmonary MRI and is particularly prevalent in patients with lung disease. Comprehensive assessment of the impact of motion compensation techniques on image quality and clinical interpretation is needed.

A Missing Link: The Double-Slit Experiment and Quantum Entanglement

Entropy
This article reconsiders the double-slit experiment by establishing a new type of relationship between it and the concept of entanglement. While the role of entanglement in the double-slit experiment has been considered, this particular relationship ...

Comparison Between Respiratory‐Triggered and Free‐Breathing Signal Acquisition Methods for Single‐Voxel Phosphorus Magnetic Resonance Spectroscopy of the Liver on a Clinical System

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The optimal protocol for clinical liver 31P‐magnetic resonance spectroscopy (MRS) remains unclear. Single‐voxel 31P‐MRS using image‐selected in vivo spectroscopy (ISIS) employs respiratory‐triggering (RT) or free‐breathing (FB) acquisition.

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.

Free‐Breathing Fat Quantification Using a Phase Error‐Corrected Cartesian Acquisition With Spiral Profile Ordering

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a phase‐corrected time‐interleaved multi‐echo gradient echo Cartesian acquisition with spiral profile ordering (TIMGRECASPR) for abdominal large‐FOV proton density fat fraction (PDFF) mapping at 3 T, demonstrating its sampling flexibility and inherent self‐gating capabilities at high isotropic resolutions.

Respiratory Motion Management in Abdominal MRI: Revisiting the Gap Between Technical Advances and Clinical Translation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT The inherently slow acquisition speed of MRI makes abdominal imaging highly sensitive to respiratory motion artifacts. Since the early days of MRI, the development of respiratory motion compensation techniques has been an active research topic, and this field has seen substantial progress.

Arc‐ZTE: Continuously‐Slewed Zero‐TE Imaging With Incoherent Temporal Sampling for Near‐Silent Dynamic MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable flexible dynamic and DCE MRI with low acoustic noise and high spatiotemporal resolution using zero echo time (ZTE) imaging. Methods This work proposes Arc‐ZTE, a technique in which the readout gradients of ZTE are continuously‐slewed to form arcs in k‐space that are sequentially rotated to yield an incoherent trajectory ...
