Figure 6a:

Agreement of hepatic proton density fat fraction (PDFF) assessments between convolutional neural network (CNN)−predicted and manual liver segmentation. (a) Linear regression and (b) Bland-Altman analysis of hepatic PDFF estimations computed from multiecho unenhanced low-flip-angle two-dimensional multiecho spoiled gradient-echo MRI with variable T2_* weighting (2D-SPGR) MR images. (c) Linear regression and (d) Bland-Altman analysis of hepatic PDFF estimations from multiecho unenhanced low-flip-angle three-dimensional multiecho spoiled gradient-echo MRI with variable T2_* weighting (3D-SPGR) MR images.
