FIGURE 6.

Scatterplots and Bland-Altman plots comparing T1, T2, and PD values of plaques and NAWM calculated from 3D-QALAS acquired with and without CS. The solid black lines in the scatterplots represent the linear regression fit, and the center solid lines of the Bland-Altman plots represent mean differences. The dotted lines represent the agreement limit, which was defined as the mean difference ± 1.96 × SD of the difference between the measurements with and without CS. SD, standard deviation; CS, compressed sensing; PD, proton density; MVF, myelin volume fraction; NAWM, normal-appearing white matter.
