When an intrahepatic nodule was visualized on abdominal ultrasonography, we used our two reporting systems. Although both were widely used in Japan, in recent years LI-RADS was proposed as an international reporting system. Of particular note is US LI-RADS, which is designed for abdominal ultrasound examinations. LI-RADS is used in the diagnostic algorithm of the 2018 Practice Guidance from the American Association for the Study of Liver Diseases, and US LI-RADS plays an important role in surveillance. Verification of the diagnostic capability of these systems will be important going forward.
