Multiparametric MRI for Preoperative T-Staging of Gastric Cancer: Added Value of Multiorientational Anatomic Imaging
Impact: mpMRI protocol with multiorientational anatomic images including orthogonal-axial images significantly outperformed mpMRI without them for gastric cancer T-staging, regardless of T-substages (pT1-pT4a), thereby aiding personalized therapeutic decision-making. Multiorientational anatomic images with orthogonal-axial images should be included in standardized mpMRI protocol.

Improving the accuracy of MRF-based abdominal T1-mapping at 7T and beyond
Impact: Investigating
the role of pause durations in Magnetic Resonance Fingerprinting based methods
might aid in the development of quantitative imaging sequences for ultra-high
field (≥7T) body imaging.

The Effect of Head Coil Configuration and Channel Count on the Quality and Accuracy of Double Inversion Recovery (DIR) Brain
Impact: Increasing receiver channel count substantially enhances quantitative DIR metrics (SNR and CNR), but subjective radiological perception does not always correlate. These findings guide MRI teams in selecting coils that balance quantitative performance, diagnostic utility, and patient comfort in clinical neuroimaging

Enhanced Visualization of Perianal Fistula Using Deep Learning-Based Reconstruction of Isotropic CE-T1WI
Impact: DLR
enables faster acquisition of high-quality isotropic CE-T1WI images, improving
diagnostic confidence in perianal fistula evaluation while reducing scan time
and motion artifacts.

Day-to-Day Reproducibility of a Clinically Accessible 31P-MRSI for Liver Metabolism
Impact: The study enhances the research and clinical utility of 31P-MRSI, making it a promising tool for noninvasive liver metabolism monitoring. This study lays the groundwork for future investigations that could lead to improved diagnostics and treatment monitoring for liver diseases.

Quantifying Bone Marrow Fat Changes in Ankylosing Spondylitis Before and After Treatment Using mDixon MRI
Impact: The results demonstrate that reduction in inflammation could be associated with an increase in bone marrow fat, providing clinical value for future research.

Corrected Liver T1 (cT1) Can Be Measured Using Freely Available T1 Mapping Acquisitions
Impact: Liver cT1 measurements can now be obtained on scanners that
do not have access to MOLLI-T1 mapping sequences. This would help to advance
the widespread adoption of standardized cT1 measurements for the non-invasive
assessment of liver disease.

Impact of Compressed-Sensing MRI on Brain Age: Whithin-Subject Comparison of Conventional and Accelerated T1 Sequences
Impact: We show that
accelerated MRI protocols may systematically bias brain age estimates from T1-weighted scans, calling for harmonization across acquisitions. This informs
neuroscientists and clinicians to control for protocol effects, enabling more
reliable longitudinal and multi-site studies using brain age.

3D-EPI outperforms 2D-EPI for High Resolution Retinotopic fMRI Using Population Receptive Field Mapping
Impact: This work provides evidence to justify and encourage the use of 3D-EPI over 2D-EPI for population receptive field mapping using BOLD-fMRI, both with and without application of thermal denoising.

Model-Based Passive Needle Tracking for MR-guided Percutaneous Interventions: A k-space hybrid approach
Impact: This study developed and validated a model-based method for passive needle tracking in MRI. Instead of relying on image reconstruction, the proposed method estimates needle orientation directly from undersampled k-space data using a model-based approach.

Towards Diffusion Model-based Compensation of T2*-induced Blurring in Ultrashort TE MRI – A Simulation Study
Impact: The proposed
diffusion model framework addresses T2*-induced blurring in ultrashort echo
time MRI.
By integrating a physics-informed signal decay
simulation based on tissue-specific relaxation, it demonstrates a pathway
towards improved reconstruction quality, with potential clinical benefits in
musculoskeletal and neuroimaging.

Using Native Cardiac T1 Mapping to Predict Post-contrast Cardiac T1 Mapping by Conditioned Diffusion Model
Impact: The conditioned diffusion
model successfully predicted post-contrast T1 mapping from pre-contrast T1 mapping
and 8 MOLLI images. The satisfactory performance of the prediction confirmed
the feasibility of generating post-contrast T1 and ECV without the use of
contrast agents.

3D CAIPI-bSSFP with Sliding-Window Acceleration for Layer fMRI
Impact:
This work operationalizes 3D-bSSFP as a practical alternative to GE-EPI for fMRI, delivering distortion-free, higher-SNR imaging and improved temporal resolution through sliding-window reconstruction. It enables more accurate localization, facilitates robust registration with anatomy, and lowers the barrier to wider adoption. |
