The Effectiveness of Multilayer Spiral CT in the Diagnosis of Atypical Liver Abscess and Its Differential Diagnosis from Liver Cancer
Objective:To investigate the effectiveness of multi-slice spiral CT(MSCT)in the diagnosis of atypical liver abscess and differential diagnosis of liver cancer.Methods:From February 2018 to February 2022,40 patients with atypical liver abscess were selected as observation group,and 30 patients with liver cancer were selected as control group.All the patients were diagnosed by pathology and examined by msct,and the results were compared.Results:The plain scan density and venous phase density of the observation group were significantly higher than those of the control group,while their arterial and delayed phase densities were significantly lower than those of the control group(P<0.05).The observation group showed significantly higher rates of wall integrity,intrauterine low-density,perfusion abnormalities,and intrahepatic bile duct/hepatic artery/portal vein abnormalities compared to the control group,with significantly lower rates of centripetal delayed enhancement compared to the control group(P<0.05).The CT plain scan of atypical liver abscess shows uneven density,blurred interior,and blurred edges of the lesion.After enhancement,the lesion indicates a"clustered"sign.The venous phase CT shows obvious enhancement imaging at the edge of the abscess,while the balanced phase CT shows isodensity shadows.Thelesion area is significantly reduced compared to the early stage,and this sign is not observed in liver cancer patients.Conclusion:Multi-slice spiral CT can differentiate atypical liver abscess from liver cancer.
