Schemes A and B are described in Table 5. Pa values are for comparisons of diagnostic performance between scheme A and LI-RADS v2018 using McNemar’s test, andPb values are for comparisons of diagnostic performance between scheme B and LI-RADS v2018 using McNemar’s test. PPV, positive predictive value; NPV, negative predictive value
