Reproducibility study of intravoxel incoherent motion and apparent diffusion coefficient parameters in normal pancreas

Figure 1 True diffusion coefficient, false diffusion coefficient, and perfusion fraction values of the pancreatic head, body, and tail on different devices. A: True diffusion coefficient values; B: False diffusion coefficient values; C: Perfusion fraction values. PaH: Pancreas head; PaB: Pancreas body; PaT: Pancreas tail; D: True diffusion coefficient; f: Perfusion fraction; D*: False diffusion coefficient.

Figure 2 Intraclass correlation coefficient map of pairwise comparison between different machines in different parts of the pancreas. ^aP < 0.05. ICC: Intraclass correlation coefficient; PaH: Pancreas head; PaB: Pancreas body; PaT: Pancreas tail; D: True diffusion coefficient; f: Perfusion fraction; D*: False diffusion coefficient.

Figure 3 Comparison of consistency of true diffusion coefficient, false diffusion coefficient, and perfusion fraction values measured using different machines. A: True diffusion coefficient (D) average in pancreatic head (PaH); B: False diffusion coefficient (D*) average in PaH; C: Perfusion fraction (f) average in PaH; D: D average in pancreatic body (PaB); E: D* average in PaB; F: f average in PaB; G: D average in pancreatic tail (PaT); H: D* average in PaT; I: f average in PaT.
