Following the Condoleezza Rice paraphrase: 'Distrust and Verify' I inquired my inerrant (LOL) Dr. Google. The result used the singular MAYO clinic when asked specifically if Choline PET CT scans were available at one of the other sites. Had it been available at other sites the response could have been more transparent.

Incidentally, I had misremembered it's use. I had thought it was good for PSMA negative PCa rather than undetectable PSMA. Supposedly 10% do not light up. Possibly it was initial use after MRI detectable PSMA negative (10%)? I believe the newly FDA approved F18 version of Pilarify is useful for 0.2 through 0.75. Jump in and clarify my errant takeaways?
