Intramyocardial Hemorrhage: An Enigma for Cardiac MRI?

Figure 1

Microvascular obstruction on EGE and LGE imaging. Cardiovascular magnetic resonance has been performed 5 days after PCI in a 54-year-old male patient with anterior ST-elevation myocardial infarction. On T1 early gadolinium enhancement (EGE) images ((a), (b)), the persistent microvascular damage appears dark (so-called “dark zones”) (black arrows) within late gadolinium enhancement area, representing the myocardial MVO on septal and anterior wall. White asterisk is the massive thrombus inside the ventricle apex ((a), (b)). T1 LGE short axis images of the same patient ((c), (d)) show transmural late gadolinium enhancement on the anteroseptal wall and a dark zone within this area indicating MVO (red arrows).
