undetectable, it's very confusing that neither you nor your doctor can trust either dexa. I would want the doctor to pursue the accuracy.
Your doctor might be thinking that you'd want to continue a medication for osteoporosis despite the accuracy of the results.
I do wonder why the anabolics-- Tymlos or Forteo haven't been part of the discussion about medications from the beginning.
It is safe to guess that you are having a good response with Reclast. And you can guess that a third year would be helpful.
Getting a second opinion from a radiologist or even questioning the radiology office where you had the scans could be a struggle. It is a struggle you shouldn't have to handle.
I see Forteo as more advantageous for your bones than Reclast.
