However, the radioactive iodine uptake ( nuclear thyroid uptake test ) may still be helpful in the diagnosis and management of amiodarone-induced hyperthyroidism.
2.
Thyroid uptake measurements ( I-123 or I-131 ), which are used to differentiate causes of hyperthyroidism, are generally unreliable in patients who have been taking amiodarone.
3.
The scientists found no evidence of increased thyroid stimulation as a result of exposure to cold, and no ethnic difference in the thyroid uptake and excretion of the tracer.
