Background: The purpose of this study is to evaluate the value of computed tomography (CT) / magnetic resonance imaging (MRI) fusion imaging technology in the diagnosis and staging of liver cancer. Materials and Methods: Sixty patients with primary hepatocellular carcinoma diagnosed by histopathology and cytology who visited our hospital from April 2021 to May 2023 were selected. All patients underwent CT and MRI single mode scans, as well as CT/MRI fusion imaging scans. Based on the pathological diagnosis results, the consistency and accuracy of three imaging methods in evaluating the number, maximum diameter, and staging of liver cancer patients were compared. Results: CT/MRI fusion imaging can more accurately determine the number (F=8.62, P<0.001), maximum diameter (F=86.69, P<0.001), and pathological staging of liver cancer lesions compared to single CT or MRI. In terms of determining the number of tumors, CT/MRI fusion imaging is superior to CT (Kappa 0.695 vs 0.654) and MRI (Kappa 0.872 vs 0.695). In terms of evaluating the maximum pathway, CT/MRI fusion imaging has the highest consistency with MRI results (Kappa 0.931), which is significantly better than CT (Kappa=0.818). In staging judgment, CT/MRI fusion imaging improves the diagnostic accuracy of stages II and III tumors. Conclusion: The CT/MRI fusion imaging technology, which integrates the advantages of CT and MRI imaging examination modes, can improve the display rate, quantitative and staging evaluation accuracy of liver cancer lesions. And it is worthy of further promotion to improve the imaging fine diagnosis level of liver cancer. |
