Dark-blood imaging with cardiac motion artefacts. a) Myocardial signal loss (arrow) due to incomplete re-inversion of the myocardial magnetisation. b) Partial blood signal (arrow) due to incorrect inversion time of the blood magnetisation. c) Good blood signal nulling, without loss of myocardial signal. In this last example the inversion pulse thickness and timing were optimal for darkening the blood signal.
