Figure 3:

Liver segmentation accuracy of the initial convolutional neural network (CNN) on images with different technical parameters (ie, echo time [TE]) and MR techniques (unenhanced low-flip-angle two-dimensional multiecho spoiled gradient-echo MRI with variable T2* weighting [2D-SPGR] vs unenhanced low-flip-angle three-dimensional multiecho spoiled gradient-echo MRI with variable T2* weighting [3D-SPGR]). Each boxplot summarizes Dice scores on image series acquired with the same imaging technique and TE. Dices scores for image series acquired with 2D SPGR and 3D SPGR MRI sequences were plotted separately in, A, and, B, respectively. A representative MR image acquired by using each TE and MR technique is shown along with the mean Dice score ± standard deviation.
