A 1.5-cm sized hepatocellular carcinoma in a 45-year-old man with 28.2 kg/m2 body mass index. A Standard dose CT (17.1 mSv) arterial and delayed phase, B low-dose CT (12.0 mSv) arterial and delayed phase, and C ultra-low-dose CT (5.1 mSv) arterial and delayed phase. On SDCT (A), both readers detected the lesion as hepatocellular carcinoma. However, reviewer 1 could not detect the lesion on LDCT (B) and ULDCT (C). Reviewer 2 detected the lesion but was characterized as benign (LI-RADS 3)on LDCT (B) and ULDCT (C). Reviewer 1 and reviewer 2 rated the overall image quality as 5 and 4 respectively for SDCT (A), 3 and 4 respectively for LDCT (B), and 2 and 4 respectively for ULDCT(C)
