¹A significant difference.

mean ± SD were calculated from the combined data of two radiologists' measurements. All CRs are presented in absolute values. 95%CI: 95% confidence intervals; DLR: Deep learning-based reconstruction; FOCUS: Field-of-view optimized and constrained undistorted single-shot; FOCUS-conv: Conventional field-of-view optimized and constrained undistorted single-shot; ADC: Apparent diffusion coefficient; MPD: Main pancreatic duct; CR: Contrast ratio.
