One of the new dual energy applications for the Somatom Definition from Siemens is syngo DE Heart PBV (Perfusion Blood Volume), which provides color-marking of non-perfused parts of the myocardium during cardiological examinations. Moreover, a specific application enables the isolated display of the heart, for example without thorax structures. The heart perfusion is examined primarily after an infarction to determine damaged areas of the organ. DECT for the first time allows to detect a stenosis and the stenosis degree as well as the location and extent of the resulting reduced perfusion in the myocardium in a single scan.
