Abstract
Objective To explore the application of enhanced multi-slice spiral CT(MSCT)in the evaluation of efficacy of ultrasound-guided radiofrequency ablation for small liver cancer.Methods 136 patients with small liver cancer who un-derwent ultrasound-guided radiofrequency ablation were selected in our hospital.All patients underwent enhanced MSCT ex-amination and digital subtraction angiography(DSA)examination at 1 month after surgery.DSA examination Results were tak-en as the gold standards to assess the efficiency of enhanced MSCT in evaluating efficacy.Results Among 136 patients with 176 lesions at 1 month after radiofrequency ablation,DSA examination showed 119 lesions of complete ablation and 57 residual lesions,and enhanced MSCT examination showed 120 lesions of complete ablation and 56 residual lesions.The sensi-tivity,specificity,accuracy rate,positive predictive value,negative predictive value and Kappa value of enhanced MSCT in e-valuating the ablation efficacy were 70.17%,86.55%,81.25%,71.43%,85.83%and 0.570,which had good consistency with the DSA detection results.Conclusion Enhanced MSCT scan can clearly observe the changes of lesions of patients after ul-trasound-guided radiofrequency ablation for small liver cancer,and can effectively evaluate the efficacy and guide subsequent treatment.关键词
