Fig. 1. Results of JAFROC analyses Fig. 1. Results of JAFROC analyses. In first analysis, all lesions (A) were included, while second analysis included only small lesions ≤ 3 mm (B). In both analyses, area under AFROC1 curve (Az) was significantly greater in non-MIP and MIP iMSDE-TSE as compared to that in non-MIP and MIP iMSDE-TSE (all, p < 0.001). However, there is no significant difference in Az for non-MIP and MIP iMSDE-TSEs, and Az is also not significantly different in non-MIP and MIP 3D-GREs. AFROC1 = alternative free-response receiver operating characteristic 1, JAFROC = jackknife alternative free-response receiver operating characteristic, MIP iMSDE-TSE = maximum intensity projection of improved motion-sensitized driven-equilibrium prepared contrast-enhanced 3D T1-weighted turbo-spin echo imaging, MIP 3D-GRE = maximum intensity projection of contrast-enhanced 3D T1-weighted gradient-echo imaging, non-MIP iMSDE-TSE = 1-mm images of improved motion-sensitized driven-equilibrium prepared contrast-enhanced 3D T1-weighted turbo-spin echo imaging, non-MIP 3D-GRE = 1-mm images of contrast-enhanced 3D T1-weighted gradient-echo imaging Fig. 1.
