Keywords: Quantitative Imaging, Diffusion/other diffusion imaging techniques
Motivation: High-resolution diffusion imaging is often perceived as less beneficial at ultra-high magnetic fields due to shorter T2 relaxation times. However, it is critical for detecting small lesions and assessing cartilage integrity.
Goal(s): Our goal was to achieve high-resolution diffusion imaging that leverages the advantages of ultra-high magnetic fields.
Approach: We employed diffusion-weighted DESS imaging to estimate diffusion tensor and fractional anisotropy in hand imaging.
Results: DW DESS yielded superior image quality compared to conventional spin-echo EPI. It shows promise as a high-resolution diffusion imaging method, harnessing the potential benefits of ultra-high magnetic fields for musculoskeletal applications.
Impact: Our study shows that DW DESS imaging offers high-resolution diffusion imaging benefits at ultra-high magnetic fields, particularly in musculoskeletal applications, with superior image quality and clinical relevance.
