Apparently in 3 tries Mythbusters managed to fool the fMRI lie test once. They didn't experiment much with different techniques, I would fully expect success rates to get much worse than that as people get more time to find good techniques for beating the test.

It wouldn’t be hard to make the scan uninterpretable either, which is a seperate failure mode.
