Detecting reperfusion myocardial hemorrhage with T2 and T2* maps at 1.5T

Table 1 Mean T2* and T2 values from hemorrhagic, non-hemorrhagic and remote territories were computed by averaging across all the days from all the animals

Region	Remote Myocardium	Hemorrhagic infarction (MH+)	Non-hemorrhagic infarction (MH-)	% Change with respect to remote myocardium
Technique	MH+	MH-
*T2 (ms)**	40.5 ± 5.0	23.0 ± 4.9	43.3 ± 5.6	-42.1 ± 14.1%*	7.9 ± 17.3%
T2 (ms)	54.9 ± 6.0	62.3 ± 5.1	72.5 ± 4.3	12.8 ± 14.4 %	35/3 ± 11.3%*

Mean percentage changes of T2* and T2 values in hemorrhagic and nom-hemorrhagic infarctions with respect to remote territories are shown. Statistically significant changers (p<0.05) are denoted with an asterisk (*). While there was a significant decrease in T2* in hemorrhagic infarctions with respect to remote territories, T2 changes were insignificant. In non-hemorrhagic infarctions T2 was significantly higher, while T2* change was insignificant.
