ABSTRACT
Objective To observe the value of contrast-enhanced ultrasound (CEUS) in the evaluation of efficacy of Argon-Helium cryoablation therapy for liver malignancies.Methods A total of 27 patients with 27 lesions of liver malignancies underwent ultrasound-guided Argon-Helium cryoablation therapy.CEUS was used to evaluate the local response and compared with contrast-enhanced CT (CECT).Results One month after Argon-Helium cryoablation therapy,21 lesions (77.78%) were diagnosed as complete ablation with CEUS and 22 (81.48%) with CECT.Contrast enhancement within lesions was demonstrated in 6 lesions (22.22%) with CEUS and 5 (18.52%) with CECT.As compared to CECT,the sensitivity,specificity,positive and negative predictive value,and accuracy of CEUS in diagnosing tumor residue 1 month after treatment was 80.00% (4/5),90.91% (20/22),66.67% (4/6),95.24% (20/21),and 88.89% (24/27) .respectively.Conclusion CEUS is an effective alternative for the evaluation of efficacy of Argon-Helium cryoablation in the treatment of liver malignancies.
