What is your actual TSH level?  Is that the only thyroid related test you've had?  Please post whatever thyroid related test results you have and be sure to include reference ranges, as those vary lab to lab and have to come from your own lab report.

The thyroid is not located in the chest; it's located in the lower neck, below the adam's apple.

You need to get your doctor to give you a full explanation of the CT results, so you aren't left in doubt.
