Re: Difference between goiter and nodule?
If you get it done at a hospital, you can always call and request copies of prior testing, including imaging reports and copies of the u/s or CT itself.
Also, if you ask, your dr's office HAS to give you copies of your records. It's your legal right. They might charge a small photocopying fee, but that's ok.
When all this started for me a year ago, I went and got copies of everything I could get my hands on as far as test results, imaging reports, etc. from several years prior.
It helps to know your history and find any patterns or trends in your labs (if any). It's also good for keeping track of the size of your nodule(s) as you get subsequent ultrasounds.
