Abstract
Objective:To evaluate the effect of iodine concentration of contrast material on detection of small hepatocellular carcinoma (SHCC) with multi-detector row CT by using arterial phase and portal venous phase enhanced scanning.Methods:Ninety-five patients with HCC were examined by hepatic plain CT and contrast-enhanced CT including arterial phase (AP) and hepatic parenchymal phase (HPP) scanning prospectively. Patients were randomized into two groups to receive Iopamidol 370 mg I/ml (48 patients) (1.5 ml/kg body weight) and 300 mg I/ml (47 patients) (1.85 ml/kg body weight) respectively with a fixed injection duration of 30 seconds. The images were interpreted by radiologists and the CT results were compared with the pathological results. The detection sensitivity for small tumors (≤3 cm) and iodine concentration groups were calculated and analyzed.Results:A total of 259 lesions were detected with 101 ≤3 cm in size. For AP, the sensitivity of Iopamidol 370 mg I/ml group was significantly higher than Iopamidol 300 mg I/ml. For HPP, there were no significant differences between groups. Conclusions:High iodine concentration contrast material could improve the detection of SHCC for AP.关键词
