Feasibility of Half-Dose Gadoxetic Acid-Enhanced Liver MRI at 5.0 T: A Prospective Intrapatient Comparison with Full-Dose 3.0 T

Key Points

• This study aims to evaluate the feasibility of half-dose gadoxetic acid-enhanced MRI at 5.0 T for liver imaging.
• Conducted a prospective intrapatient comparison of half-dose 5.0 T MRI and full-dose 3.0 T MRI.
• Assessed image quality, HBP acquisition time, and motion artifacts in both imaging techniques.
• Half-dose 5.0 T MRI maintained diagnostic image quality comparable to full-dose 3.0 T MRI.
• Achieved a 25% reduction in HBP acquisition time.
• Reduced motion artifacts, improving overall scanning efficiency.
