Abdominal CT scan with intravenous contrast agent is used to diagnose hepatocellular carcinoma. Three-phase scanning (before contrast administration, immediately after contrast administration, and again after a delay) is employed to increase the ability of the radiologist to detect small tumors.  It is important to optimize the parameters of the CT examination, because the underlying liver disease (e.g. hepatitis B) that most hepatocellular carcinoma patients have can make the findings more difficult to appreciate.
