Don't I know it.

It's possible to extract them, but they rapidly decompose outside the body. I'm sure they have some kind of self-diagnostics, but not that I've been able to access - and that's me saying that. Figures the one thing their people were any good at was cryptography.

So... I won't say it's impossible, nothing's impossible. [ Except things he doesn't want to believe. ] But in the short term, the detector's more likely to yield any useful data.
