Zusammenfassung

Flussmessungen gehören zum Standardrepertoire der MRT des Herzens. Dabei stehen die Quantifizierungen intra- und extrakardialer Shuntvolumina sowie von Klappenvitien im Vordergrund. Aber auch die Abschätzung von Stenosen, beispielsweise des Aortenisthmus v. a. über einen assoziierten Kollateralfluss, sind klinisch akzeptiert. Bei der Planung und Auswertung einer Phasenkontrastflussmessung müssen einige Regeln beachtet werden, um fehlerhafte Ergebnisse zu vermeiden. Dann aber ist die Phasenkontrastflussmessung eine wertvolle Ergänzung für die tägliche Routine in der Herzbildgebung.

Abstract

Phase-contrast flow measurements have become an established method in cardiac MRI. The quantification of intra- and extracardiac shunt volumes as well as the evaluation of valvular disease and aortic coarctation have proved their clinical usefulness. There are some rules that have to be followed when performing and analyzing phase-contrast flow measurements. With these rules in mind, quantitative phase-contrast flow measurements are a reliable and precise method for clinical use of cardiac MRI.
