Objective:To explore the diagnostic value of CT and magnetic resonance imaging(MRI)in patients with liver cancer(HCC),in order to provide reference for early clinical screening diagnosis and targeted intervention.Methods:108 cases of suspected HCC patients admitted to our hospital from February 2022 to August 2023 were retrospectively collected.Using pathological biopsy as the"gold standard",they could be divided into HCC group(43 cases)and benign tumor group(65 cases).The detection rates of CT density enhancement and MRI signal enhancement were compared between the two groups.The diagnostic results and efficacy of CT and MRI alone and combined were analyzed,and the detection rates of different size lesions were compared.Results:The detection rates of CT density enhancement and MRI signal enhancement at arterial,portal and equilibrium stages in HCC group were significantly higher than those in benign tumor group(P<0.05).The sensitivity of CT and MRI combined diagnosis was 97.67%,higher than that of single diagnosis,and the missed diagnosis rate was 2.33%,lower than that of single diagnosis(P<0.05).The total detection rate of CT and MRI combined diagnosis and the detection rate of<2cm lesions were 97.67%and 93.75%,respectively,which were higher than that of single diagnosis(P<0.05).Conclusion:The combined diagnosis of CT and MRI has high diagnostic sensitivity and low missed diagnosis rate in HCC patients,which can provide a reliable basis for clinical diagnosis of HCC.
