Hat die Myokardszintigrafie heute noch einen Stellenwert in der Kardiologie?

Abstract

Myocardial perfusion scintigraphy evolved into the modality of choice regarding non-invasive imaging for the presence of obstructive coronary artery disease (CAD) in patients with clinically suspected or already known CAD in the 80ies and 90ies. However, new non-invasive imaging modalities such as cardiovascular magnetic resonance imaging (CMR) have been established in the last years and are challenging the clinical predominance of myocardial perfusion scintigraphy in evaluating myocardial ischemia and thereby constituting the gatekeeper to invasive cardiac catheterization. In particular, CMR-based methods (comprising dobutamine-stress-CMR and adenosine-perfusion-CMR) offer at least equal diagnostic accuracy compared to conventional myocardial perfusion scintigraphy while having less side effects (e. g. no radiation burden). Therefore, the present and future clinical value of myocardial perfusion scintigraphy may become seriously questioned. In this review, the present clinical value of myocardial perfusion scintigraphy is critically assessed in comparison to CMR-based imaging modalities.
