ALFF analysis
calcarine fissure
CORTEX
Compared with HCs, all patients at POD 3 had significantly lower ALFF in the right middle frontal gyrus (MFG), right supplementary motor area (SMA), bilateral precuneus, right calcarine fissure and surrounding cortex (CAL), and left triangular part of inferior frontal gyrus (IFGtriang) (Table Comparisons of ALFF values between patients at POD 3 and HCsCoordinates (ALFF, amplitude of low‐frequency fluctuation; MNI, Montreal Neurological Institute; POD3, postoperative day 3; HCs, healthy controls; L, left; R, right.Comparisons of ALFF between patients in postoperative day 3 and healthy controls.
