a. Measured T2 on phantoms with relaxation times close to normal (N) and oedematous (O) myocardium with a subset of the protocols tested. Red and blue dotted lines show the true T2 of phantoms N and O respectively. The three points for each phantom and protocol represent the three heart rates (with higher heart rates leading to longer measured T2 values) and error bars show the mean±s.d. over heart rate. Protocol details are in Table 1. b. Discrimination of oedematous (arrowed) and remote myocardium in acute myocardial infarction using protocol D.
