Abstract

Abstract: Objective The aim of this study was to investigate diagnostic efficacy of CT dynamic enhancement scan in patients with liver cirrhosis and intrahepatic space-occupying lesions (SOL). Methods 120 patients with intrahepatic SOL were encountered in our hospital between February 2018 and May 2023, and all underwent CT dynamic enhancement scan. Golden diagnosis was based on histo-pathological examination by fine needle aspiration biopsies or post-operational tissues. Results Pathological diagnosis included hepatocellular carcinoma (HCC) in 84 cases (70.0%)and focal proliferative nodules (FPN) in 36 cases(30.0%) in our series; in lesions of HCC, percentage of intensified enhancement at arterial phase was 100.0%, equal enhancement at portal phase was 56.0% and low enhancement at delayed phase was 97.6%, while in lesions of FPN, the percentages of equal enhancement at arterial, portal and delayed phases were 88.9%, 94.4% and 100.0%; of the 120 cirrhotics with intrahepatic SOL, CT scan diagnosed primary liver cancer in 83 cases (69.2%) and FPN in 37 cases (30.8%), with sensitivity, specificity, accuracy, negative predictive value and positive predictive value of 96.4%, 94.4%, 95.8%, 91.9% and 97.6%, respectively (Kappa=0.902). Conclusion The feature of intrahepatic SOL showing by CT dynamic enhancement scan at different phases could help clinicians make a correct diagnosis, and deal with it appropriately.
