=Scans for Thyroid Cancer=

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:

$$\text{Required dose} (microCi)=\frac{Size~in~grams \cdot (100~to~180microCi)}{24~hour~%RAIU}$$
 * 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)
