Verschiedene Untersuchungsprotokolle und Möglichkeiten der Strahlenreduktion bei der Myocardperfusionsszintigrafie

Zusammenfassung

Die Myocardperfusionsszintigrafie stellt unverändert eine wichtige diagnostische Methode zur Evaluation der hämodynamischen Relevanz einer koronaren Herzkrankheit dar. Mit der Einführung der CZT-Kameras sowie anderer technischer Neuerungen auch bei konventionellen Gammakameras wie z. B. die IQ-SPECT-Technologie sowie verbesserte Auswertealgorithmen, konnte die Strahlenbelastung pro Untersuchung kontinuierlich gesenkt werden, sodass sich die moderne nuklearmedizinische Perfusionsbildgebung sowohl hinsichtlich der diagnostischen Spezifität und Sensitivität als auch der Strahlenbelastung gegenüber den konkurrierenden Methoden nicht zu verstecken braucht.

Abstract

Myocardial perfusion scintigraphy continues to be an important diagnostic tool for the evaluation of coronary heart disease. With the introduction of CZT cameras and other technical innovations also in conventional gamma cameras such as IQ-SPECT technology and improved evaluation algorithms, the radiation exposure per examination has been reduced continuously. As a consequence, modern nuclear medicine perfusion imaging does not have to hide in terms of diagnostic specificity and sensitivity as well as the radiation exposure to the competing methods.
