Visualization of tissue alterations in thyroid nodules after microwave ablation: sonographic versus scintigraphic imaging.

Objective: The aim of this study was to elucidate the potential of B-mode sonography, colour-coded Doppler sonography and scintigraphic imaging as diagnostic methods for the evaluation of treatment success and follow-up of thyroid nodules after microwave ablation.

Materials And Methods: Thirty-six thyroid nodules in 33 patients were subjected to microwave ablation and were evaluated by means of B-mode sonography, colour-coded Doppler sonography and scintigraphic imaging before and after ablation. B-mode sonography results were characterized by echogenicity that was assigned ultrasound scores (US).
