This analysis of 129 adults compared the wave-image quality of two-dimensional (2D) and three-dimensional (3D) magnetic resonance elastography (MRE) across a range of body mass indices (BMIs). Wave-image quality of each scan was measured quantitatively by region of interest (ROI) areas. We found that 3D MRE provides higher wave-image quality compared to 2D MRE and that wave-image quality was not statistically associated with BMI (p=0.3422). Further research with larger BMI cohorts is needed to confirm our findings.
