Aktuelle Untersuchungsprotokolle der Myokardperfusionsszintigrafie

Zusammenfassung

Die Myokardperfusionsszintigrafie stellt ein nicht-invasives bildgebendes Verfahren im Rahmen der Diagnostik und Risikostratifizierung von Patienten mit koronarer Herzkrankheit (KHK) einschl. der therapeutischen Entscheidungsfindung dar. In den letzten Jahrzehnten führten Entwicklungen in den Bereichen der Gerätetechnik, der Radiopharmaka, der pharmakologischen Belastungsverfahren und der Akquisitionsprotokolle zu einer weiteren Verbesserung der diagnostischen Genauigkeit. Die nachfolgende Arbeit gibt eine aktuelle Übersicht über Radiopharmaka, Belastungsprotokolle, Empfehlungen zur Patientenvorbereitung und Akquisitionsstrategien der Myokardperfusions-SPECT.

Abstract

Myocardial perfusion scintigraphy is a noninvasive imaging procedure for diagnosis and risk stratification of patients with coronary artery disease therapeutic decisions. In the last decades advances in technology, radiopharmaceuticals, pharmacologic stress testing and acquisition protocols have led to further improvement of diagnostic accuracy. This paper provides an overview of radiopharmaceuticals, stress testing protocols, acquisition strategies and recommendations for the preparation of patients for myocardial perfusion SPECT.
