Cardiovascular Magnetic Resonance T2-STIR Imaging is Unable to Discriminate Between Intramyocardial Haemorrhage and Microvascular Obstruction

Research output: Contribution to book/anthology/report/proceedingConference abstract in proceedingsResearchpeer-review

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. T2-STIR was unable to differentiate between IMH and MVO in myocardial ischemic/reperfusion injury.
