Image quality evaluation of six DWI acquisition strategies. The heat maps displayed in the right of box plots show the corresponding post hoc comparison results. For example, the heat map exhibited in the first row demonstrates the post hoc multiple comparison results in terms of sharpness scores. The values labeled in each cell represent the p values of post hoc comparison with Bonferroni adjustment. The scale bars indicate the p values (0.00–0.05), the black filled cells indicate no significant difference. The values of 0 suggest the corresponding p values are less than 0.001 according to the SPSS software
