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 underwent ultrasound-guided radiofrequency ablation were selected in our hospital.All patients underwent enhanced MSCT examination and digital subtraction angiography（DSA）examination at 1 month after surgery.DSA examination Results were taken 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 sensitivity, specificity, accuracy rate, positive predictive value, negative predictive value and Kappa value of enhanced MSCT in evaluating 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 ultrasound-guided radiofrequency ablation for small liver cancer, and can effectively evaluate the efficacy and guide subsequent treatment.
