Overview
Other Imaging Findings
Thyroid Scintigraphy
- High RAIU: de novo T4 synthesis
- Toxic adenoma
- Toxic multinodular goiter
- TSH-producing pituitary tumor
- Hcg-secreting tumor
- Hyperemesis gravidarum
- Low RAIU: released or exogenous T4
- Thyroiditis - painful, painless, post-partum
- Amiodarone toxicity
- Factitious hyperthyroidism
- Struma ovarii (rare)
- Metastatic thyroid CA (ridiculously rare)
- Thyroid-stimulating antibodies bind and stimulate the TSH receptor
- Anti-TSHR ABs are 80-95% sensitive, 80-90% specific for Graves’
