Can DKI-MRI predict recurrence and invasion of peritumoral zone of hepatocellular carcinoma after transcatheter arterial chemoembolization?

Figure 4 Box plots showing diffusion kurtosis imaging derived metrics of peritumoral zones between true and pseudo-progressing groups. A: Mean kurtosis (MK); B: Axial kurtosis (KA); C: Radial kurtosis (KR); D: Mean diffusivity (MD); E: Axial diffusivity (DA); F: Radial diffusivity (DR); G: Anisotropy coefficient of kurtosis (FAk). ^aP < 0.05; the unit of MD, DA, and DR is 10^-3 mm²/s. N = pseudo-progressing group; Y = true progressing group. FAk: Anisotropy coefficient of kurtosis; MD: Mean diffusivity; MK: Mean kurtosis; KA: Axial kurtosis; KR: Radial kurtosis; DA: Axial diffusivity; DR: Radial diffusivity.
