Myelin Measurement: Comparison Between Simultaneous Tissue Relaxometry, Magnetization Transfer Saturation Index, and T1w/T2w Ratio Methods

Scientific Reports, 2018
Magnetization transfer (MT) imaging has been widely used for estimating myelin content in the brain. Recently, two other approaches, namely simultaneous tissue relaxometry of R1 and R2 relaxation rates and proton density (SyMRI) and the ratio of T1 ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Optimizing the Relaxivity of MRI Probes at High Magnetic Field Strengths With Binuclear GdIII Complexes

Frontiers in Chemistry, 2018
The key criteria to optimize the relaxivity of a Gd(III) contrast agent at high fields (defined as the region ≥ 1.5 T) can be summarized as follows: (i) the occurrence of a rotational correlation time τR in the range of ca.

Analytical Dual Flip Angle R1 Calculation Outside the Small‐Angle Regime

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2420-2428, April 2026.
ABSTRACT Purpose To evaluate a new analytical estimator for R1 and apparent proton density (A$$ A $$) from short‐TR dual flip angle data which does not rely on the small flip angle approximation and can thus be applied to a broader range of data, especially where relatively large flip angles are needed to achieve sufficient T1‐weighting for R1 ...

Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2356-2369, April 2026.
ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

Incorporation of MoO3 Nanoparticles Into Polypropylene Fibers via Melt Spinning: Investigation of Mechanical, Thermal, and Chromic Properties

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Pure PP and PP/MoO 3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO 3 ) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.
