Abstract
Objective To compare and analyze the enhancement effects of the Iodine contrast agents with two different concentrations of 270 and 350 mg I/ml in the enhancement scan of renal multislice CT (MSCT),and to discuss the fea-sibility of the Iodine contrast agent with low concentration in the renal enhancement scan. Methods 90 patients sus-pected of nephropathy in our hospital from September 2012 to May 2014 were collected.They were randomly assigned to group A and group B,with 45 patients in each group.They were both given renal scan and multi-phase MSCT en-hancement scan respectively.The group A was given the Iodine contrast agent of 270 mg I/ml,and the group B was giv-en the Iodine contrast agent of 350 mg I/ml.CT enhancement values of the enhancement scan of abdominal aorta,bilat-eral renal artery,bilateral renal veins,bilateral renal cortex,bilateral renal medulla and bilateral renal pelvis in each phase 18 s,30 s,80 s,3-5 min after the injection were measured.Adverse effects in each group of patients were observed. Re-sults Incidence of adverse events such as fever in the group B was higher than that in the group A;the CT enhancement values of abdominal aorta,right renal artery,left renal artery,right renal vein,left renal vein,right renal cortex,left renal cortex,right renal medulla,left renal medulla,right renal pelvis and left renal pelvis in the group B were all higher than those in the group A,but the differences were not statistically significant (P<0.05). Conclusion At the same flow of in-jection,contrast agent with low concentration applied in multislice renal angiography is able to acquire satisfactory im-age,and meanwhile it is able to reduce the adverse effects induced by the contrast agent.关键词
