The results of visual evaluation by four grading system among three readout methods. The results of visual evaluation by three raters were respectively presented (a–c). In all raters, significantly higher scores were found in 3D-PSS than 2D-EPI (*a: P = 0.006, b: P = 0.02, and c: P = 0.01, respectively). In addition, visual scores of 3D-PSS tended to be higher than those of the 3D spiral readout, although statistical significance was not observed (a: P = 0.15, b: 0.97, and c: 0.52, respectively). EPI, echo planar imaging; PSS, pseudo-steady state.
