Quantitative analysis of liver function with contrast enhanced ultrasonography of liver cirrhosis / 中国医学影像技术

ABSTRACT

Objective To observe the corelation between quantitative index and the grade of the liver function with contrast-enhanced ultrasonography (CEUS) in hepatic cirrhosis. Methods Seventy-five patients of cirrhosis after HBV were divided into 3 groups (each n=25) on the basis of the liver function by Child-pugh method, while 20 healthy subjects were enrolled in the control group. The inner diameter and Doppler spectrum of right hepatic vein (RHVD, RHVF) were measured. After intravenous bolus injection 1.2 ml SonoVue, RHA and RHV were observed continually on real time, hepatic artery transit time (HATT) and hepatic vein transit time (HVTT) were recorded, then HTTs were calculated. Results In hepatic cirrhosis groups, RHVD decreased remarkably, RHVF was abnormal, HVTT and HTT were obviously shorter, and HTTs were shortened significantly.Conclusion CEUS may play an important role in qualitative evaluation of liver function, and HTT is more valuable than HVTT.
