Examples of liver surface nodularity (LSN) scores derived from routine abdominal CT images. (A, B wide FOV-top row images; small FOV-bottom images) A A 46-year-old male with abdominal pain undergoes abdominal CT. The liver has normal morphological appearance, and the LSN score was normal at 1.59. B A 55-year-old male with abdominal distension undergoes nonenhanced abdominal CT. The patient had a history of hepatitis C chronic liver disease. The liver has liver surface nodularity and the LSN score was abnormal at 2.98 indicating cirrhosis (Image courtesy: Dr. Andrew Smith, University of Alabama Medical Center, UABC, Birmingham, AL)
