Abstract
Methods In 19 patients (age 57 ± 11), a CMR study was performed 6 ± 1 days after reperfusion therapy for acute ST-elevation myocardial infarction. In a short axis orientation, covering the entire left ventricle (slice thickness 10 mm/0 mm), the following sequences were obtained: cine SSFP images for functional and volumetric analyses, T2*-weighted GE-EPI for hemorrhage; after injection of 0.1 mmol/kgBW early post-conrast IR-GE images were obtained for MO, and after 10 min, late gadolinium enhancement images were obtained for infarct size. Images were analyzed semiquantitatively using a threshold-based signal detection.

T2*-weighted cardiovascular magnetic resonance (T2*CMR) accurately quantifies myocardial reperfusion hemorrhage in vivo
In a short axis orientation, covering the entire left ventricle, the following sequences were obtained: cine SSFP images for functional and volumetric analyses, T2*-weighted GE-EPI for hemorrhage; after injection of 0.1 mmol/kgBW early post-conrast IR-GE images were obtained for microvascular obstruction (MO), and after 10 min, late gadolinium enhancement images were obtained for infarct size
