超声造影联合弹性成像评估对甲状腺良性结节微波消融术后病灶残留的应用价值OA

Objective To explore the application value of contrast-enhanced ultrasound combined with elastography in evaluation post-ablation residual lesions after microwave ablation for benign thyroid nodules.Methods Retrospective anal-ysis was conducted on the clinical data of 50 patients with benign thyroid nodules who were scheduled to undergo microwave ablation at Puning People's Hospital from January 2024 to February 2025.All patients were hospitalized and underwent ul-trasound-guided microwave ablation of thyroid benign nodules,which was performed by the same group of ultrasound physicians.After the treatment,ultrasound contrast,elastography,and ultrasound contrast combined elastography were used to evaluate the ablation effect.The application value of the three methods in evaluating residual lesions after microwave ablation of benign thyroid nodules was compared.Results The complete ablation rate differed significantly among the three groups(P＜0.05).However,there were no statistically significant differences between the combination group and the elas-tography group or between the combination group and the contrast-enhanced ultrasound group(P＞0.017).The specificity and accuracy of contrast-enhanced ultrasound combined with elastography in diagnosing residual lesions after microwave ablation of benign thyroid nodules were higher than those of elastography alone.Conclusion The combination of con-trast-enhanced ultrasound and elastography can complement each other's advantages and improve the accuracy of residual lesion assessment after microwave ablation of benign thyroid nodules.By accurately identifying residual lesions and guiding supplementary ablation,the complete ablation rate can be improved and the recurrence rate can be reduced.
