Role of cerebral blood flow changes in post-transjugular intrahepatic portosystemic shunts hepatic encephalopathy

Figure 2 Regions with significant differences showing cerebral blood flow. The color bar represents the t-values between the two groups after post hoc verification; the higher the brightness of the color, the more significant the difference. The red area indicates regions where amplitude of low-frequency fluctuation values is increased, and the blue area indicates regions where amplitude of low-frequency fluctuation values is decreased. X and Z = three-dimensional coordinates of brain structures. Before: Preoperative transjugular intrahepatic portosystemic shunts; HC: Healthy control group; 1 m: Postoperative transjugular intrahepatic portosystemic shunts at 1 month; 3 m: Postoperative transjugular intrahepatic portosystemic shunts at 3 months.
