PET med O-15-vatten påvisade myokardischemi där övrig utredning gick bet.

摘要
Elevation of troponin reflects myocardial infarction. The underlying causes should be assessed, as treatment and prognosis may differ widely. Myocardial damage with non-obstructive coronary arteries requires further evaluation including magnetic resonance tomography. We report a case of significant myocardial ischemia which was unnoticed by myocardial scintigraphy but detected by positron emission tomography (PET). The 15O-water tracer allows for quantitative assessment of myocardial perfusion including regional abnormalities and may thus diagnose microvascular dysfunction.
