The artifact seem to be the same as what I've seen (take a look at the
attached file produced with Siemens Tim Trio 3T, 12 direction
sequence). Our understanding at the time we found it was that this is
coil related problem(Transmit/Receive Head Coil), but we didn't
investigate further. It would be nice to see whether anybody can
reproduce this artifact in a stable manner.
Thanks,
Mikolaj
