Independent Component Analysis of Instantaneous Power-Based fMRI
Figure 3
The ROC curves for ICA decomposition of ip-fMRI and traditional fMRI. Plotted are the mean ROC curves of the fifty repeated procedures. For the simulation with a CNR set to be 0.5, the area under the ROC curve (AUC) is 0.9751 and 0.4896 for ip-fMRI and traditional fMRI, respectively. Briefly, CNR = 0.75, AUC = 0.9932 (ip-fMRI) and 0.9723 (traditional fMRI); CNR = 1, AUC = 1 (ip-fMRI) and 0.9993 (traditional fMRI); CNR = 2, AUC = 1 (ip-fMRI) and 1 (traditional fMRI).
