You can try calling for your results... 48 hours is probably reasonable if you haven't already heard back from them. The doctor has to review the radiologist's report before you can get the results.

I would call tomorrow so it's less likely you end up getting more vague results on a Friday afternoon again. If you only find out that you need more testing or need to see the endocrinologist sooner, at least you will know that. Hopefully you will learn more than that tho
