Multiple-TE Based Blood–Brain-Barrier Water Exchange Time Measurement Using a TE-Resolved 3D TSE Stack-of-Spirals Readout
Impact: TE-resolved ASL effectively eliminates k-space signal intensity modulation across slices and image blurring artifacts, providing a valuable tool for accurate and reliable quantification of cerebral perfusion and BBB permeability, potentially facilitating early diagnosis and monitoring of neurodegenerative diseases.

Accelerated T1-weighted MRI using Magnetization Prepared Echo-planer Fast Imaging with Steady-state Free Precession (ME-FISP)
Impact: Our proposed accelerated 3D ME-FISP sequence reduces scan time and enhances
patient comfort and clinical efficiency. Acceleration is achieved through
sequence optimization, not AI-based reconstruction, preserving high image
quality for broader research and clinical neuroimaging applications.

Simultaneous Anatomical Imaging and Metabolic Measurements Using Interleaved 1H-MRI/31P-MRS
Impact: We present an innovative, interleaved 1H-MRI/31P-MRS sequence enabling simultaneous assessment of brain anatomy and metabolism. This represents a novel step toward advanced understanding of metabolic function, providing new insight into the relationships between brain structure, function, and metabolism.

Eddy, Wideband, and bSTAR
Impact: We explored a fusion of wideband SSFP with bSTAR to relax TR constraints for high-resolution lung MRI at 3T. Due to severe eddy-current-related phase perturbations, however, we show that the two concepts cannot be combined.

Contrast basis framework for rapid MP2RAGE-style imaging
Impact: Extracting
contrast basis images from MPRAGE revealed its latent contrast structure and
enabled the construction of MP2RAGE-style images with shorter scan time than
conventional MP2RAGE.

MP-n-RAGE with acceleration and internal reference
Impact: MPRAGE is frequently used to obtain high resolution whole brain images. We added a reference GRE acquisition to the MP(2)RAGE design to allow parallel imaging without the need for an external reference or adding ACS-lines.

Receive k-Space Informed Parallel Transmit Pulse Design for SAR Reduction at Ultra High Field
Impact: Selective k-space deployment of energy-constrained parallel transmit pulses focuses RF power where homogeneity matters, preserving image quality while cutting local head SAR by 40.6%

Gradient Echo Planar Spectroscopic Imaging (GREPSI) for true brain temperature measurement
Impact: Gradient echo EPSI (GREPSI) acquisition with novel spectral image processing, makes it possible to obtain accurate and precise measurements of true temperature over much of the human brain an order of magnitude faster than prior EPSI methods.

Inter-vendor reliability of functional and structural brain connectivity in a travelling cohort
Impact: When a scanner vendor change is unavoidable in
a running study, harmonisation techniques such as neuroComBat substantially
mitigate inter-vendor variance for group analyses but not individual data,
highlighting the need for harmonisation planning and cautious interpretation of
subject-level connectomic findings.

RF Pulse Optimization for Variable Flip Angle FLEET Segmented Spin-Echo EPI Using a Differentiable Extended Phase Graph Model
Impact: Optimized RF pulses improved signal-level consistency between shots with low SAR in VFA FLEET segmented spin-echo EPI. This sequence will enable high-resolution fMRI with improved spatial and temporal specificity and with robustness to motion and between-shot phase errors.

Utility of zero-echo time neuroimaging in assessing sellar-floor cartilage structures as a biomarker for achondroplasia
Impact: In addition to assessing achondroplasia (ACH)-derived morphological complications on the
conventional imaging, zero-echo time imaging might provide a new biomarker for ACH.

Optimized susceptibility-weighted MRI for central vein sign detection in the spinal cord at 7T
Impact: A SWI phase mask was optimized using modeled intra- and extravascular
phase behavior reflecting spinal cord venous geometry and voxel anisotropy and
orientations. Application to 7 T data enabled observation of central vein sign
in multiple sclerosis patients.

MRI Goes Mobile, Part II: Extended Structural and Functional In Vivo Comparison of Mobile vs. Stationary 1.5T MRI
Impact: The
reliable and robust performance of the mobile 1.5T MRI, even after relocation, compared to a stationary 1.5T MRI, positions it as a transformative technology to enhance accessibility and enable
large-scale, diverse neuroimaging studies.

Impact:
This abstract presents a guide through the decision process of establishing a comprehensive qMRI protocol for the imaging of patients with temporal lobe epilepsy in hopes of allowing for non-invasive lesion detection and improved surgical planning |

An MRI-compatible Phantom Model for Validation of Oscillatory CSF Flow Quantification Techniques
Impact: This work supports the use of 4D Flow MRI for quantifying
ventricular CSF dynamics in controlled settings and establishes a platform for
refining imaging protocols before translation to participant studies.
