Zusammenfassung

Patienten mit einer Steinerkrankung stellen sich in der Regel mit kolikartigen Schmerzen vor. Vor Einleitung einer Therapie ist zur sicheren Diagnosestellung eine weiterführende Bildgebung erforderlich. Hierfür stehen die Sonographie, die konventionelle Röntgenabdomenaufnahme, das Ausscheidungsurogramm, die native Computertomographie (CT), die CT- und MR-Urographie und die Dual-Energy-CT zur Verfügung. Alle unterscheiden sich in der Verfügbarkeit, in der diagnostischen Sensitivität und Spezifität und in der Strahlenbelastung für den Patienten. Mit der Dual-Energy-CT wurde ein Verfahren entwickelt, das im Gegensatz zu den konventionellen die Steinzusammensetzung mit hoher Sicherheit unterscheiden und so die Therapie beeinflussen kann. In diesem Leitthemenbeitrag zur Bildgebung der Urolithiasis werden die einzelnen bildgebenden Verfahren vorgestellt und insbesondere das Dual-Energy-CT näher erläutert.
