Evaluation of Triple-phase Spiral CT for the Detection of Small Hepatocellular Carcinoma / 实用放射学杂志

ABSTRACT

Objective To investigate the features of the enhancement of SHCC at triple-phase spiral CT scanning and compare its sensitivity in different phase.Methods The pre- and post-contrast CT scanning of the entire liver in 70 patients with SHCC was carried out with a helical CT scanner. The contrast material was infused at a rate of 3ml/s, followed by sequential arterial-, portal- and equilibrium- phase scans of the liver. The number of the detected lesions was calculated in each phase, the characterization of lesions in each phase was observed.Results Of the 82 detected SHCC, the sensitivity in three phases was 92.68%, 70.73% and 73.17% respectively. The sensitivity increased significantly to 95% by combining the detection of three phases. Conclusion Triple-phase contrast enhanced spiral CT can fully demonstrate the patterns of SHCC and improve its detection rate.
