Abstract Objective To explore the imaging features and diagnostic value of liver enhanced CT and MRI in elderly patients with combined hepatocellular and cholangio carcinoma (cHCC-CC). Methods From October 2018 to September 2020, 98 elderly patients suspected to be cHCC-CC admitted to Rugao People’s Hospital, Jiangsu Province were selected as the research subjects, all patients underwent CT and MRI examinations. CT and MRI imaging features of elderly patients with cHCC-CC were analyzed. Pathological results as the gold standard, the diagnostic value of CT, MRI, and their combination in elderly patients with cHCC-CC was analyzed. Results Among the 98 elderly patients suspected to be cHCC-CC, 89 cases were cHCC-CC patients. CT plain scan showed that the liver contour was unstructured, wavy, with increased volume and uneven density, and the tumor presented mixed density or low density; plain MRI showed mosaic signs. The sensitivity of liver enhanced CT, MRI, and their combination in the diagnosis of elderly cHCC-CC was 77.53%, 92.13%, and 97.75%, respectively; the specificity was 66.67%, 77.78%, and 88.89%, respectively; the accuracy was 76.53%, 90.81%, and 96.94%, respectively. Conclusion The combination of enhanced CT and MRI in the diagnosis of cHCC-CC in the elderly is effective.
