Cutoff values were defined by highest Youden Index. ADC: Apparent diffusion coefficient, CI, confidence interval, FSF: Fat-signal fraction, FW: Fat water ratio LP/VP: Liver/pancreas and Vessel/ pancreas echo intensity ratios, MRI: Magnetic resonance imaging, US: Ultrasonography. ADC: Apparent diffusion coefficient
