Question

State whether the following statement is true or false. Iodine 123 is used in treatment of hyperthyroidism.​

Answer 1

Answer:

Moreover, scanning a thyroid remnant or metastasis with 123I does not cause "stunning" of the tissue (with loss of uptake), because of the low radiation burden of this isotope. For the same reasons, 123I is never used for thyroid cancer or Graves disease treatment, and this role is reserved for 131I.
