Figure 5

The intrinsic connectivity networks identified from ECD SPECT and eFBB PET. The images in the 1st column show the intrinsic connectivity networks derived from ECD SPECT, and the 2nd and 3rd columns from eFBB PET. Abbreviations ECD SPECT, Tc-99m ethyl cysteinate dimer single photon emission computed tomography; eFBB PET, early-phase F-18 Florbetaben positron emission tomography.
