Aim: Thyroid nodules represent a common clinical issue. Amongst other minimally invasive procedures, percutaneous microwave ablation (MWA) poses a promising new approach. The goal of this retrospective study is to find out if there is a correlation between @entity353 after 3 months and 99mTc-uptake reduction of treated thyroid nodules. @entity1 , methods: 14 @entity1 with 18 nodules were treated with MWA. Pre-ablative assessment included sonographical and functional imaging of the thyroid with 99mTc-pertechnetate and 99mTc-MIBI. Additionally, @entity1 underwent thyroid scintigraphy 24 hours after ablation in order to evaluate the impact of the treatment on a functional level and to ensure sufficient ablation of the targeted area. At a 3-month follow-up, ultrasound examination was performed to assess nodular @entity353 . Results: Mean relative nodular @entity353 after three months was 55.4    17.9% (p < 0.05). 99mTc-uptake 24 hours after treatment was 45.2    31.9% (99mTc-MIBI) and 35.7    20.3% (99mTc-pertechnetate) lower than prior to ablation (p < 0.05). Correlating reduction of volume and 99mTc-uptake, Pearson's r was 0.41 (p < 0.05) for nodules imaged with 99mTc-MIBI and -0.98 (p < 0.05) for 99mTc-pertechnetate. According to scintigraphy 99.6    22.6% of the determined target area could be successfully ablated. Conclusions: MWA can be considered as an efficient, low-risk and convenient new approach to the treatment of benign thyroid nodules. Furthermore, scintigraphy seems to serve as a potential prognostic tool for the later morphological outcome, allowing rapid evaluation of the targeted area in post-ablative examination.
