Myokardszintigraphie: Durchführung, Dokumentation und überweiserfreundlicher Befund

Zusammenfassung

Die Myokardszintigraphie stellt seit vielen Jahren einen wichtigen Baustein in der nicht-invasiven kardialen Diagnostik bei vermuteter oder bekannter koronarer Herzkrankheit dar. Aufgrund der unterschiedlichen zur Verfügung stehenden Radiopharmaka, der Kombination aus Ruhe und körperlicher oder pharmakologischer Belastung sowie der verschiedenen Kamerasysteme ist eine Vielzahl unterschiedlicher Untersuchungsprotokolle möglich. Um einen möglichst standardisierten Untersuchungsablauf zu gewährleisten, existieren eine Reihe von Richtlinien, die sich mit diesem Thema befassen und als Referenz dienen können. Der Befundbericht, als letzter Teil der Myokardszintigraphie, schließt die Untersuchung ab. Dieser Teil der Untersuchung stellt das Verbindungsglied zum Überweiser dar, so dass ihm eine besondere Bedeutung zukommt. Es empfiehlt sich ein systematischer Aufbau mit gleich bleibender und allgemein akzeptierter Nomenklatur, um dem Überweiser die Interpretation der Ergebnisse zu erleichtern. Überdies kann durch eine klare Bewertung des Untersuchungsergebnisses und eine konkrete Beantwortung der Fragestellung des Überweisers die Akzeptanz der Myokardszintigraphie als klinische Methode gewährleistet werden.

Abstract

Myocardial perfusion imaging plays an important role in the non-invasive diagnostic work-up of patients with suspected or known coronary artery disease for many years now. As a result of different radiopharmaceuticals, the combination of a resting with a stress study, the application of either physical exercise or pharmacological stress and the availability of different camera systems, several imaging protocols exist. In order to assure relatively standardized perfusion studies, several guidelines concerning the performance of perfusion imaging have been published, which may be used as a reference. The report represents the final part of a perfusion study. As it is the linkage to the clinician, who ordered the scan, it is of particular importance. Therefore, a systematic structure and a commonly used nomenclature is recommended, helping the clinician to interpret the study results. Moreover, an explicit assessment and a clear answer to the clinical question guarantees the acceptance of myocardial perfusion imaging as a clinical method.
