Brain regions with abnormal regional homogeneity in cirrhotic patients with overt hepatic encephalopathy.

Results were according to the automated anatomical labeling software package and digital atlas of the human brain. Multiple comparisons were corrected using Monte Carlo simulations with a corrected threshold of p<0.05. The threshold of the cluster size was 40 calculated by the following parameters: single voxel p = 0.01, 1,000 simulations, FWHW = 6 mm, cluster connection radius = 5 mm with grey matter mask.
