1.5 tesla machine

All patients and controls were subjected to pelviabdominal MRI using a 1.5-tesla machine (Philips, Inginea). The T2 MRI-weighted images were obtained in axial and coronal axes with respiratory gating, using the following parameters: 80 ms echo time, 1250 ms repetition time, 400 × 400 matrix size, 6-mm slice thickness, 400 × 350 × 196 mm field of view.
The DTI was performed using a single-shot fast spin-echo echo-planar sequence with respiratory gating, using the following parameters: 85 ms echo time, 6000 ms repetition time, 128 × 128 matrix size, 2.5-mm slice thickness, 224 × 224 × 196 mm field of view, and 3 averages.
The apparent diffusion coefficient (ADC) of the liver was estimated using the b values of 50, 400, and 800 s/mm². The ADC values were calculated at each of the 4 right liver segments, and the mean of them was calculated to get the final ADC. We omitted the left lobe to avoid motion artifacts (caused by cardiac movements). The collected ADC values were compared between patients and controls, and then correlated with the degree of liver fibrosis in the patient group. Merged images between colour-mapped axial cuts of DTI and axial T2 WI were obtained, and example images are presented in Figure 1 and Figure 2.
