Imaging characteristics of brain microstructure and cerebral perfusion in Crohn’s disease patients with anxiety: A prospective comparative study

Figure 4 Brain regions with decreased diffusion kurtosis imaging parameters in Crohn’s disease patients without anxiety compared to healthy controls. A: Comparison of the axial kurtosis (AK) and radial kurtosis (RK) values among patients without anxiety Crohn’s disease (CD), patients with anxiety CD, and healthy controls (HC); B: AK values of brain regions were significantly lower in patients with CD without anxiety compared with HC; C: RK values of brain regions were significantly lower in patients with CD without anxiety compared with HC. ^aP < 0.05; NS: Not statistically significant; CD: Crohn’s disease; HC: Healthy control; AK: Axial kurtosis.
