Detection rate and enhanced effects of different iodine concentration of contrast agent for patients with liver cirrhosis of different time phase hepatocarcinoma in 64-MDCT / 局解手术学杂志

ABSTRACT

Objective To compare the clinical diagnosis effect of high and common iodine concentration of contrast agent to patients with liver cirrhosis hepatocarcinoma in 64-MDCT.Methods Ninety patients who diagnosed with cirrhosis and hepatoma by biopsy in our hospital from January 2015 to December 2016 were randomly divided into observation group(n =45) and control group(n =45).The observation group and the control group separately accepted 350 mgI/mL and 300 mgI/mL Lohexol enhancement.The CT values of different enhanced parts,detection rate of lesions and the incidence of adverse reactions were chosen as clinical diagnosis indexes.Results The CT value of liver parenchyma,aorta and portal vein in observation group were particularly or very particularly higher than those of control group (P ＜ 0.05).145 and 110 lesions were respectively detected in observation group and control group.It showed higher diagnostic sensitivity of observation group in three phases (P ＜ 0.05) and good safety in 64-MDCT.Conclusion High concentration iodine contrast agent can remarkably improve the detection CT value and detection rate of liver cancer patients with liver cirrhosis in 64-MDCT,with less adverse reactions.
