Scans for Benign Disease Multinodular Goiter Indications Procedure Graves Disease Indications Procedure Scans for Thyroid Cancer Indications Procedure Thyroid Ablation Indications Thyroid cancer - Either localized or metastatic Benign disease refractory to conservative treatment and/or causing symptoms or complications Procedure 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) Ziessman0-323-02946-9 -- "Nuclear Medicine: The Requisites, Third Edition (Requisites in Radiology)."
