Quantitative T1 and T2 Mapping of Rabbit Knees after Focal Radiation: Effects of 1% Gd Immersion and Post-Treatment Interval
Impact: High-field ex vivo MRI with standardized Gd immersion enables reproducible
quantitative mapping of radiation-induced skeletal changes. The method
identifies early, region-specific sensitivity in the growth plate and
metaphysis, providing a translational model for evaluating radiation effects on
developing bone.

Comparative Vascular Imaging with Gadopiclenol and Gadolinium in Cardiac MRI using Ultrashort Echo Time (UTE) Sequence.
Impact: Integrating
high-relaxivity gadopiclenol contrast with UTE sequences allows robust vascular
imaging offering a clinically feasible, time-efficient, and dose-sparing
alternative for cardiovascular MRI.

Placental stiffness determined by virtual MR Elastography throughout gestation
Impact: Placental stiffness is an important indicator of
a healthy pregnancy, and virtual MR Elastography can be used to measure placental
stiffness throughout gestation using IVIM.

Multicenter Assessment of Open-MOLLI: A Cross-Vendor T1 Mapping Study
Impact: The study of vendor-neutral quantitative MR Open-MOLLI sequence reproducibility across vendors and sites will help clarify their impact on cardiac T1-mapping standardization. This will facilitate future multi-center studies, enhancing reproducibility and clinical translation of quantitative MRI.

Visualization of Glymphatic Flow Using IR-Prepared GRE Diffusion and Directional ΔS Mapping
Impact: This study introduces an IR-prepared GRE diffusion approach with
directional ΔS mapping, enabling non-invasive visualization of slow
perivascular fluid motion. It provides a framework for quantifying glymphatic
transport dynamics and may facilitate early detection of impaired clearance in
neurodegenerative diseases.

Towards an Open Face Head-Neck MRI Coil Using Optically Transparent Anterior Channels for Pediatric Brain-Spinal Cord Imaging
Impact: Open-face head-neck MRI coils experience a significant reduction in SNR in the midline parts of the brain and the spinal cord. Results suggest that an acceptable SNR in the
regions of interest can be achieved using optically transparent anterior channels.

MRI in Clinical Practice: Non-Contrast BOOST MRI for Left Atrial Appendage Thrombus Detection as a Clinical Alternative
Impact: Left atrial appendage thrombi are typically diagnosed by transesophageal echocardiography or CTA. Non-contrast BOOST MRI provides a vital alternative for diagnosis when standard methods are contraindicated, such as in critically ill or renally impaired patients.

DL-ZTE for structure-function lung imaging in healthy volunteers: Comparison to UTE and conventional ZTE
Impact: Deep-learning reconstruction enhances ZTE lung MRI quality, boosting SNR to levels comparable to UTE. Structural and functional images can be reconstructed from a single free-breathing ZTE scan. ZTE’s lower acoustic noise than UTE makes it ideal for paediatric lung imaging.

Comparing 3D radial phyllotaxis and stack-of-stars trajectories for free-breathing liver imaging
Impact: This study highlights that with the
same number of total radial spokes, 3D radial phyllotaxis offers reduced
structured artifacts due to undersampling compared to stack-of-stars (SOS),
suggesting its potential to enhance imaging quality in free-breathing liver
MRI.

Multi-slice-angle BOLD for spatial-dependent optimal signal: Does only susceptibility matter?
Impact: Onsite measurement of the optimal slice angle in BOLD per subject and various targeting regions could be useful for psychiatry or neurodegenerative disease research which needs functional mapping in anterior temporal lobe and ventral pre-frontal cortex.
