Recent studies have used cardiovascular magnetic
resonance (CMR) and T2-weighted short tau inversion
recovery (T2-STIR) imaging to detect intramyocardial
haemorrhage (IMH) as a measure of ischemic/reperfusion
injury. We investigated the ability of T2-STIR to
differentiate between microvascular obstruction (MVO)
and IMH in an experimental pig model of
ischemic/reperfusion injury. T2-STIR results were
validated by histopathology showing a sensitivity of
100% and specificity of 29% respectively, for detection
of IMH. T2-mapping showed no significant difference
between T2 values from areas with MVO versus MVO and
IMH. In conclusion, T2-STIR was unable to differentiate
between IMH and MVO in myocardial ischemic/reperfusion
injury.
