Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Age > 18 years
Hyperthyroidism or subclinical hyperthyroidism caused by a solitary hyperactive thyroid nodule (HTN), either located in an otherwise normal thyroid gland, or in a multinodular goitre (MNG), with a diagnosis based on the following characteristics:
- Blood TSH level below the lower limit of normal, and associated with either normal or elevated FT4 and FT3 levels
- Anti-TSH antibody negative
- Solitary HTN confirmed by a diagnostic I-123 scintigraphy, corresponding with a well demarcated thyroid node on ultrasound, cystic degeneration < 75%, nodule size <50 mm.
- Treatment with RAI indicated, and eligible for RFA treatment
- Signed informed consent Patients who are ineligible for randomization due to unsuitability for RFA, may be eligible for the RAI cohort group.
Exclusion Criteria:
- Multifocal HTN
- HTN > 50 mm
- Presence of a medical device susceptible to disturbances caused by RFA generated currents
- Patients with physical or behavioural disorders that preclude safe isolation in radiation protection rooms, or safe RFA procedure under local anesthesia
- Patients with dysphagia, oesophageal stenosis, active gastritis, gastric erosion, a peptic ulcer or impaired gastro-intestinal motility
- Uncorrectable haemorrhagic diathesis
- Pregnant or breastfeeding women

Other: Radioactive iodine, cohort
This group contains patients who are not randomized and have given informed consent undergo treatment with radioactive iodine (I-131) according to local standard (e.g.
fixed dose or dose-calculation based on iodine uptake and thyroid nodule mass).
