Zusammenfassung

Die kontrastmittelverstärkte Sonographie im phaseninvertierten Kontrast- harmonischen Modus stellt eine vielversprechende neue Technik zur Detektion und Charakterisierung von Leberherden dar. So wird berichtet, dass sich maligne von benignen Lebertumoren mit einer fast 100%igen Sensitivität differenzieren ließen bzw. eine Artdiagnose mit einer Genauigkeit von über 90% möglich sei.

Über 7 Fälle aus dem eigenen Patientengut wird im Folgenden exemplarisch berichtet. Abschließend werden die so ermittelten Ergebnisse mit dem derzeitigen Wissensstand verglichen und diskutiert. Zusammenfassend können durch den zusätzlichen Einsatz der signalverstärkten Sonographie die meisten Leberläsionen korrekt charakterisiert werden; atypische Phänomene sollten dennoch bekannt sein, um die Befunde kritisch bewerten zu können.

Abstract

Contrast-enhanced sonography performed as phase inversion harmonic imaging is a promising new technique for detection and characterization of hepatic foci. It has been reported that malignant liver tumors can be differentiated from benign entities with almost 100% sensitivity and that diagnosis of the type is possible with an accuracy of over 90%.

The following report describes seven of our own cases and then compares the results we obtained with current knowledge, followed by a discussion. In summary, most hepatic lesions can be correctly characterized by supplemental use of enhanced sonography; practitioners should nevertheless be aware of atypical phenomena to be able to critically evaluate the findings.
