No Worries: The radiation from 1 head ct does not measurably increase your risk of cancer in the future. The radiation was no where near your testicles, and even if it was, there is no measurable risk for birth defects in children.

Can an abdominal CT scan with and without contrast detect micronodular adrenal adenomas? What's the false negative possibilities?

Can an abdominal CT scan with and without contrast detect micronodular adrenal adenomas? What's the false negative possibilities?

Adrenal adenomas: With most gland problems, first figure out if the hormones are elevated. If so, THEN go looking for the tumor. This is because all glands form nodules, but these nodules often have no consequence. If you have a hormone elevation (Cushings, pheo, aldosteronoma) and the source is the adrenal, the CT will almost always find it. But this is complicated. See your Endocrinologist. ...Read more
