Comparative Precision of 3D MRE and 2D MRE for Measurement of Liver Stiffness in Adults with Severe Obesity

Listen to this summary

The authors aimed to compare the precision of two-dimensional (2D) and three-dimensional (3D) MR elastography (MRE) in measuring liver stiffness in adults with severe obesity. Their findings indicate that 3D MRE demonstrates superior test-retest repeatability, between-field-strength reproducibility, and between-day reproducibility compared to 2D MRE, although it also has a higher technical failure rate.
