Role of 18-FDG/PET in evaluation of hepatocellular carcinoma managed locally by transarterial chemoembolization compared to triphasic computed tomography

摘要

Abstract Background This study was done to evaluate the role of FDG/PET compared to CECT in evaluating HCC after local interventional treatment. We evaluate forty-six patients with known history of TACE as a locoregional treatment of pathologically proved HCC. There were forty-three males and three females. Results The collected data were statistically analyzed, and we found that FDG-PET has a sensitivity of 94%, specificity of 84%, positive predictive value of 86.7%, negative predictive value of 86.4%, and accuracy of 93.4% in the detection of residual or recurrent at the managed tumor bed compared to CECT which shows a sensitivity of 94%, specificity of 84%, positive predictive value of 86.7%, negative predictive value of 86.4%, and accuracy of 93.4 %). Combined views ( FDG-PET/CT ) are better in evaluation. Conclusion FDG-PET is better in the detection of residual or recurrence in HCC which is locally managed by TACE.
