Accuracy of Automated Liver Contouring, Fat Fraction, and R2* Measurement on Gradient Multiecho Magnetic Resonance Images

Objective This study aimed to evaluate the performance of an automated workflow of volumetric liver proton density fat fraction (PDFF vol ) and R2* quantification with automated inline liver volume (LV) segmentation. Methods Dual-echo and multiecho Dixon magnetic resonance images were evaluated in 74 consecutive patients (group A, PDFF < 10%; B, PDFF ≥ 10%; C, R2* ≥ 100 s −1 ; D, post-hemihepatectomy). The values of PDFF vol and R2* vol...
