Zusammenfassung
Hintergrund
Die Störung der Blut-Hirn-Schranke – gemessen mittels Magnetresonanztomographie – stellt kein zuverlässiges Zeichen von Gliomen dar. Mittels Positronenemissionstomographie (PET) kann ein Aminosäuretransport in die Tumorzellen gemessen werden, unabhängig von der Blut-Hirn-Schranke.
Ziel
Die Arbeit fasst ausgewählte Literatur zur Rolle der PET bei Gliomen zusammen.
Methoden
Anhand von PubMed wurde eine selektive Literaturrecherche durchgeführt.
Ergebnisse
In prägnanter Form erläutert der Artikel die Grundlagen und Durchführung der Aminosäure-PET. Klinische Anwendungen erfassen Tumorausdehnung, Grading und Differenzierung von benignen Befunden, Therapieplanung und -Kontrolle sowie die Differenzierung von Gliomrezidiven und therapiassoziierten Veränderungen.
Schlussfolgerung
Die PET mit radioaktiv markierten Aminosäuren stellt eine wertvolle Zusatzmethode in der Diagnostik und beim Therapiemonitoring von Gliomen dar.
Abstract
Background
Blood-brain barrier disruption as assessed with magnetic resonance imaging is not a reliable sign of gliomas. Positron emission tomography (PET) can be used to measure the transport of amino acids into tumor tissue, independent of the blood-brain barrier.
Objective
This article reviews selected literature about the role of PET in gliomas.
Methods
A search for relevant literature was carried out in PubMed .
Results
In a concise manner this review explains the basic principles and procedures of amino acid PET. Clinical indications cover differentiation of benign findings, glioma delineation, grading, treatment planning and response, as well as differentiation between relapse and treatment-related changes.
Conclusion
PET with radiolabeled amino acids represents a valuable additional tool for the diagnostics and treatment monitoring of gliomas.
