Abstract:
Objective To explore the impact factors of volume reduction rate(VRR)of benign thyroid nodules after thermal ablation based on conventional ultrasound and contrast-enhanced ultrasound(CEUS)manifestations.Methods Totally 238 patients with benign thyroid nodules who underwent thermal ablation were retrospectively enrolled and divided into VRR＜75%group(n=93)and VRR≥75%group(n=145)according to VRR of lesions 12 months after treatment.Multivariate logistic regression analysis was used to screen the independent impact factors of VRR of lesions 12 months after thermal ablation based on conventional ultrasound and CEUS manifestations.Receiver operating characteristic curve was plotted,the area under the curve(AUC)was calculated to evaluate the efficacy of the combination of the above factors for predicting VRR of lesions.Results High echo,calcification,cystic and solid components,high enhancement,enhancement loss and high ablation energy were all independent risk factors,while circular enhancement was the independent protective factor of VRR of benign thyroid nodules 12 months after thermal ablation(all P＜0.05).The AUC of combination of the above factors for predicting VRR of benign thyroid nodules 12 months after thermal ablation was 0.926.Conclusion High echo,calcification,cystic and solid components,high enhancement,enhancement loss and high ablation energy were all independent risk factors,while circular enhancement was the independent protective factor of VRR of benign thyroid nodules 12 months after thermal ablation.
