Does iodine contrast affect your thyroid?
I am a 40 year old female. I want to know if iodine contrast affects thyroid?
1 Answer
Per the ACR:
Thyroid and iodine contrast
Contrast medium injection does not affect thyroid function tests (e.g., T3, T4, TSH) in patients with a normal thyroid. Routine monitoring of thyroid function tests before contrast medium injection in patients with a normal thyroid is not indicated even in areas where there is dietary iodine deficiency.
