Abstract:
Objective:To explore application value of observed tumor enhancement characteristics by dynamic enhancement magnetic resonance imaging(MRI)in assessing blood supply of small hepatocellular cancer.Methods:The cases data of 80 patients with suspected small hepatocellular cancer who admitted to Yichang Central People's Hospital from January 2019 to January 2023 were retrospectively analyzed.The enhancement characteristics of tumors of all patients were real-timely observed by MRI scanner,which included the relative enhancement degree(RSI),enhancement mode,time-signal intensity curve,etc.The enhanced characteristics of the tumors were recorded,which were combined with a series of variables included disease history,tumor type,tumor size,the number of tumor,liver function status of patients to conduct analysis.The receiver operating characteristics(ROC)curve was adopted to analyze the application value of the observed tumor enhancement characteristics by dynamic enhancement MRI in assessing the status of blood supply of small hepatocellular cancer.Results:There were statistically significant differences in the RSI(F=40.151,P<0.05),enhancement degree(x2=27.374,P<0.05),and time-signal intensity curve(x2=20.950,P<0.05)of dynamic enhanced MRI among different stages of small hepatocellular cancer.The differences in medical history(F=17.844,P<0.05),tumor type(x2=11.219,P<0.05),tumor size(x2=14.081,P<0.05),and the number of tumor(x2=74.310,P<0.05)among different enhancement degrees of arterial phase were also statistically significant.With the enhancement degree increased,the asymptomatic period increased,and the number of malignant tumors increased,and tumor size increased.The differences in liver function status among different time-signal intensity curves were statistically significant(F=330.182,325.872,216.689,P<0.05).The area under curve(AUC)value of the ROC of the RSI of observed tumor enhancement characteristics by dynamic enhancement MRI was 0.582(95%CI:0.493-0.670)in assessing blood supply of small hepatocellular cancer.Conclusion:Dynamic enhancement MRI can observe the vascular generation and hemodynamic changes of small hepatocellular cancer,which has a certain application value in assessing blood supply of small hepatocellular cancer,and it can help doctors to choose appropriate treatment plan and assess treatment effect.
