The goal of this study, consisting of 207 patients, was to quantify the improvements that can be gained at 3.0T abdominal MRI with the application of parallel radiofrequency transmission (MTX) primarily by correcting standing wave artifacts, and whether the impact of MTX correlates with body habitus. Significant improvements in mean signal-to-noise and contrast-to-noise ratios in left liver were observed with the application of MTX at two separate anatomical locations. These improvements in SNR and CNR were also demonstrated to increase as the cross-sectional body area increased using analysis of variance and linear regression model analysis.
