Purpose The aim of this study was to evaluate the decrease of benign thyroid nodules after bipolar radiofrequency ablation (RFA) in a 3-month follow-up using a multiple overlapping shot technique ('MOST'). Methods A total of 18 patients with 20 symptomatic benign thyroid nodules (17 cold nodules, 3 hyperfunctioning nodules) were treated in one single(More)
PURPOSE To determine the safety and efficacy of bipolar radiofrequency ablation (RFA) in benign thyroid nodules. METHODS 23 patients with 24 symptomatic benign thyroid nodules (21 regressive, 3 adenomas) ranging in volume from 0.5 to 112 ml (mean ± sd: 18 ± 24.4 ml) underwent bipolar RFA. Pain during the procedure was measured on a 10-point scale.(More)
A thyroid-like gelatin model was used to determine potential superiority of a new navigation system for ultrasound (US)-guided electrode insertion called EchoTrack, featuring a US probe with an integrated electromagnetic field generator, in comparison with conventional US when performing radiofrequency ablation. In order to compare 20 navigated ablations(More)
Purpose: Microwave ablation (MWA) represents a novel thermal ablative treatment of benign thyroid nodules. The aim was to determine the energy required per ml volume reduction in order to match the required energy to the volume-of-interest (VOI). Materials and Methods: 25 patients with 25 nodules (6 solid, 13 complex and 6 cystic) were treated by microwave(More)
Percutaneous radiofrequency ablation (RFA) of thyroid nodules is an alternative to surgical resection that offers the benefits of minimal scars for the patient, lower complication rates, and shorter treatment times. Ultrasound (US) is the preferred modality for guiding these procedures. The needle is usually kept within the US scanning plane to ensure(More)
3 adult monkeys, one Macaca fascicularis and two Macaca mulatta, were whole-body irradiated with 1 Gy gamma-rays (60 Co). Reciprocal translocations induced in spermatogonial stem cells were scored as translocation multivalents in primary spermatocytes from 7.5 to 27.5 months after exposure. The translocation yields ranged from 4.1% at the earliest to 1.8%(More)
