(A) Change in mean perfusion (post-pre diet PCASL) across all regions of significance after the MMKD. Error bars represent ±1 standard error from the mean. *Significant at p < 0.05. (B) Regions where MCI showed greater perfusion compared to SMC in response to MMKD (p < 0.005, k = 112). All images presented in neurological orientation. (C) Regions where MCI showed greater perfusion than SMC in response to MMKD (p < 0.005, k > 112); k = number of contiguous voxels, and MNI coordinates for peak voxels within significant cluster. Abbreviations: MCI, mild cognitive impairment; MMKD, modified Mediterranean-ketogenic diet; MNI, Montreal Neurological Institute; PCASL, pseudo continuous arterial spin labeling; SMC, subjective memory complaints.
