Zusammenfassung

Die PET/CT wird bei vielen kindlichen Tumorentitäten eingesetzt und hat beim Hodgkin-Lymphom bereits Eingang in nationale und internationale Leitlinien gefunden. Die PET ermöglicht eine semiquantitative Messung der metabolischen Tumoraktivität und damit eine frühe Beurteilung des Therapieansprechens sowie der Vitalität von Tumorrestgewebe oder eines Rezidivs. Für verschiedene Fragestellungen stehen unterschiedliche metabolische und molekulare Marker zur Verfügung.

In dieser Übersichtsarbeit werden Indikationen für PET im Kindesalter sowie die besonderen Anforderungen in der Durchführung und Befundung dargelegt. Abschließend wird die Bedeutung der neuen PET/MRT für die Diagnostik kindlicher Tumore diskutiert.

Abstract

PET/CT is used in many pediatric malignancies and is part of international guidelines for Hodgkin-lymphoma imaging. PET is useful for the evaluation of metabolic tumor activity. Thus it is helpful for the early determination of response to therapy and to delineate vital tumor tissue in residual or recurrent tumor. This review outlines different indications for PET in childhood using targeted molecular probes. Age related patient preparation and patterns of tracer distribution need special consideration during image analysis. The incremental value of PET/MRI for the imaging of pediatric malignancies is discussed.
