Impact: This study presents the first systematic cross-method investigation of EPT repeatability in the human brain. This work marks an important step towards standardising EPT methodology and promoting reproducibility. Demonstrating repeatability is crucial for the clinical translation of EPT.

Impact: Defect distribution index (DDI) is a novel MRI-based index that quantifies the spatial pattern of ventilation defects. It provides complementary information to VDP and demonstrates stronger correlations with lung function impairment.

Impact: The nomogram integrating Hindex, stiffness volume entropy, and viscosity-based maximum habitat proportion holds potential to predict the IC response.

Impact: Simulations in realistic microstructure ground truths offer a better interpretation of time-dependent kurtosis and facilitate the design of kurtosis-based acquisitions for precise tissue characterization.

Impact: Multiparametric qMRI provides detailed assessment of tissue microstructure and microenvironment. qMT reflects myelin integrity, while multi-component relaxometry captures neurodegenerative changes. Yet, MT effects can bias multi-component quantification. Integrating both techniques can facilitate better understanding of disease pathogenesis and progression.

Impact: A method for generating isotropic magnetization transfer ratio maps at ultra-low field was developed, and demonstrated excellent repeatability, unlocking myelin imaging for portable MRI systems and broadening access to advanced neuroimaging in point-of-care scanning, and community and resource-limited settings.

Impact: Subspace reconstruction achieves similar accuracy and diagnostic quality to dictionary learning while enabling faster, temporally consistent 3D whole-heart cine + T1 mapping in a single 5-minute free-breathing scan, streamlining cardiac MR protocols.

Impact: This work demonstrates the feasibility of 3D T1rho-weighted MRI for T1rho mapping at 6.5 mT. Despite quantitative bias relative to spectroscopic measurement, the proposed approach provides effective contrast among samples and serves as a foundation for future applications.
