Structural and Functional Deficits in Patients with Poststroke Dementia: A Multimodal MRI Study

Figure 5

The receiver operating characteristic (ROC) curves for using GMV/fALFF values for the classification of PSND versus PSD patients. Specifically, the AUC in the left cerebellum posterior lobe, left medial prefrontal cortex, left superior frontal gyrus, right superior temporal gyrus, and right inferior frontal gyrus are 0.804, 0.531, 0.502, 0.783, and 0.717, respectively. AUC: area under the curve; fALFF: fractional amplitude of low-frequency fluctuation; CPL_L: left cerebellum posterior lobe; mPFC_L: left medial prefrontal cortex; SFG_L: left superior frontal gyrus; STG_R: right superior temporal gyrus; IFG_R: right inferior frontal gyrus.
