Altered White Matter Integrity in Patients with Retinal Vein Occlusion: A Diffusion Tensor Imaging and Tract-Based Spatial Statistics Study

Figure 4

ROC curve analysis of the mean FA and RD values for altered brain regions. (a) The areas under the ROC curve for the FA values were as follows: the body of corpus callosum (CC), 0.862 (; 95% CI: 0.719–1.000); the right posterior thalamic radiation (RPTR), 0.883 (; 95% CI: 0.759–1.000); the left posterior thalamic radiation (LPTR), 0.959 (; 95% CI: 0.896–1.000); the right sagittal stratum (RSS), 0.770 (; 95% CI: 0.595–0.946); the left sagittal stratum (LSS), 0.837 (; 95% CI: 0.667–1.000); the right cingulum (RC), 0.893 (; 95% CI: 0.773–1.000); the left fornix/stria terminalis (LF/ST), 0.796 (; 95% CI: 0.620–0.971). (b) The areas under the ROC curve for the RD values were as follows: the body of CC, 0.923 (; 95% CI: 0.816–1.000); the RPTR, 0.918 (; 95% CI: 0.817–1.000); the LPTR, 0.969 (; 95% CI: 0.917–1.000); the RSS, 0.959 (; 95% CI: 0.896–1.000); the LSS, 0.908 (; 95% CI: 0.792–1.000); the RC, 0.847 (; 95% CI: 0.685–1.000); the LF/ST, 0.908 (; 95% CI: 0.792–1.000). AUC: area under the curve, FA: fractional anisotropy, RD: radial diffusivity, ROC: receiver operating characteristic, CC: corpus callosum, RPTR: right posterior thalamic radiation, LPTR: left posterior thalamic radiation, RSS: right sagittal stratum, LSS: left sagittal stratum, RC: right cingulum, LF/ST: left fornix/stria terminalis.
