Quantifying Cardiac, Respiratory, and Low Frequency Components of CSF Motion From fMRI Inflow Effects

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...

TRACC‐PHYSIO: Time‐Domain Resolution‐Aligned Cross‐Correlation to Estimate PHYSIOlogical Coupling and Time Delays in Dynamic MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To validate a method to assess cardiac and respiratory brain pulsations in slowly sampled dynamic MR scans. Cardiac and respiratory pulsations are key drivers of neurofluid circulation. However, resolving their temporal dynamics requires fast imaging, which is not achievable in many dynamic MR acquisitions.

Quantitative Susceptibility Mapping of Kidney Stones: An Ex Vivo MRI Phantom Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To visualize and characterize the five most common kidney stone types based on their magnetic susceptibilities in MRI using QSM. Methods Three water‐based agar phantoms were constructed, containing a total of 53 ex vivo kidney stones of varying types and sizes.

Zero‐Shot Self‐Supervised Learning of Single Breath‐Hold Magnetic Resonance Cholangiopancreatography (MRCP) Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate the feasibility of zero‐shot self‐supervised learning reconstruction for reducing breath‐hold times in magnetic resonance cholangiopancreatography (MRCP). Methods Breath‐hold MRCP was acquired from 11 healthy volunteers on 3T scanners using an incoherent k‐space sampling pattern, leading to a 14‐s acquisition time and an

Assessing and Quantifying Variability Across Vacuum‐Assisted Resin Infusion Variants for Aerospace‐Grade Composite Manufacturing

Polymer Composites, EarlyView.
Radar‐plot comparison of consolidation quality and flexural performance of composite laminates manufactured by six vacuum‐infusion routes, evaluated at the resin‐inlet and vacuum‐port regions. ABSTRACT Conventional vacuum‐assisted resin transfer molding (C‐VARTM) is recognized as a cost‐effective resin infusion technique for manufacturing large‐scale ...
