Eur Radiol: How to accurately measure the volume of necrotic tissue after radiofrequency ablation of benign thyroid nodules

According to the guidelines, radiofrequency ablation (RFA) is a safe and effective method for the treatment of benign thyroid nodules.

According to the guidelines, radiofrequency ablation (RFA) is a safe and effective method for the treatment of benign thyroid nodules.

Evaluation indicators after ablation include volume reduction rate (VRR), treatment success rate, etc.

Contrast-enhanced ultrasound (CEUS) is a harmonic contrast imaging technique, contrast agents by using a second generation evaluation micro vessels for the detection and characterization of focal lesions.

Recently, a study published in the journal European Radiology explored the observers of gray-scale and Doppler ultrasound (US) and contrast-enhanced ultrasound (CEUS) measuring the ablation volume (Va) of benign thyroid nodules after radiofrequency ablation (RFA) Reliability and consistency within and between observers.

A total of 190 benign thyroid nodules in 173 patients were included in this study, and each patient received radiofrequency ablation.

The average follow-up time was 23.
