Wolff-Chaikoff effect
autoregulatory phenomenon, whereby a large amount of ingested iodine acutely inhibits thyroid hormone synthesis within the follicular cells, irrespective of the serum level of thyroid-stimulating hormone (TSH)
Jod-Basedow phenomenon
hyperthyroidism following iodine intake in a person with long term underlying thyroid disease.
Graves treatement dose of I-131 calculation
estimated thyroid gland isze x (0.13-0.18) mCi/g of thyroid tissue / 24 hour RAIU
Multinodule goiter treatment dose of I-131 compared to Grave’s disease
MNG is increased dose compared to GD
