  • Thyroid cancer - Either localized or metastatic

Procedure edit

  • Calculation of dose
    • The dose should be calculated with two different variables: The weight of the gland(in grams), and how much it's 24 hr uptake is (For example, 24% would be 0.24). You can then use the following formula:
 
    • The weight of the gland is a very subjective measurement. One can attempt to approximate the gland weight with the following guidelines:
      • A regular non-palpable thyroid gland weighs approximately 15-20 grams.
      • A thyroid that you cannot see but is palpable weighs approximately 30-40 grams (needs verification)
      • A gland that is easily seen and palpated can be anywhere from 40-200 grams (needs verification)
