3D Balanced Steady-State Free Precession (bSSFP) Imaging at 0.05 T

Motivation: Ultra-low-field (ULF) MRI technology holds significant promise for advancing medical imaging by offering low-cost and portable solutions for point-of-care applications. These advancements have the potential to improve access to medical imaging in resource-limited settings, thereby benefiting underserved populations and enhancing diagnostic capabilities to ultimately improve patient care. Goal(s): The implementation of a highly efficient protocol for ULF MRI. Approach: A 3D bSSFP protocol was implemented and optimized. Results: The study successfully implemented bSSFP protocol at 0.05 T and demonstrated its utility for imaging the brain, cervical spine, and knee. Impact: In this study, a bSSFP protocol was successfully implemented at 0.05 T by demonstrating its utility for imaging the brain, cervical spine, and knee. These findings enable the potential of high-quality ULF MRI.
