Wow. I'll have to look for that article and abstract. Sadly,
it is not in PubMed.
Just from personal experience and our vet's experience it
is better locally than it used to be but such high error
rates in that study are a real concern.
Long ago (long enough ago that Lysodren was used and
that now abandoned approach was actually new) we had a
male who looked like a bilateral on ultrasound but he instead
had lymphoma in the right adrenal and his left adrenal was
clean despite what the ultrasound said.
(The Lysodren wound up atrophying his good adrenal
so even though Pred and removal of his right adrenal kept
his lymphoma under control for 14 months he did wind up
being one of the first ferrets on Fludrocort (before publication
of the Colorado study which was probably happening about
the same time independently).
Thank you so very, very much for yet another chance to
learn!
To each tool and technique its best applications... Thank
goodness for ultrasounds for some other things such as
cardiomyopathy and ultrasound guided aspirations for
cytology.
