Comparison of the Efficacy of Multi-slice Spiral CT Perfusion Imaging and Enhanced Magnetic Resonance Imaging in the Diagnosis of Early-Stage Hepatocellular Carcinoma
Objective:To explore the application value of multislice spiral CT(MSCT)perfusion imaging and enhanced magnetic resonance imaging(DCE-MRI)in the diagnosis of early liver cancer.Methods:86 patients with suspected hepatocellular carcinoma admitted to our hospital from January 2021 to October 2023 were selected,and all of them underwent MSCT perfusion imaging and DCE-MRI with pathological examination as the gold standard to analyze the detection rate of hepatocellular carcinoma and diagnostic efficacy,and the consistency of diagnosis of different methods with the gold standard was verified by Kappa test.Results:The gold standard of 86 suspected patients confirmed the diagnosis of 45 cases,of which 44 cases were detected by MSCT perfusion imaging,with a positive rate of 97.78%(44/45);40 cases were detected by DCE-MRI,with a positive rate of 88.89%(40/45);The diagnostic sensitivity and accuracy of MSCT perfusion imaging were higher than that of DCE-MRI(P<0.05);The Kappa test showed that the diagnosis of MSCT perfusion imaging was highly consistent with the gold standard Kappa value of 0.930;The Kappa value between DCE-MRI diagnosis and the gold standard is 0.745,and the consistency is still acceptable.Conclusion:MSCT perfusion imaging is of higher value in the diagnosis of early hepatocellular carcinoma,which can reduce the risk of missed diagnosis and misdiagnosis,and realize early precision treatment.
