Neue Entwicklungen in der PET/CT-Hybridbildgebung: Nutzen für die Strahlentherapie?

Zusammenfassung

Mit den aktuellen Entwicklungen der PET/CT-Bildgebung werden wichtige Anforderungen für den Einsatz der biologischen Bildgebung für die bildgestützte Hochpräzisionsstrahlentherapie wie Gewährleistung der bestmöglichen Koregistrierung, hohe Genauigkeit der quantitativen funktionellen PET-Parameter adressiert. Diese technischen Entwicklungen umfassen die Time-of-Flight (TOF) Technik, Verbesserung der tomografischen Bildrekonstruktion, Weiterentwicklung von Methoden zur Berücksichtigung von atmungskorrelierter Bewegung und die Datenverarbeitung. Damit werden die technischen Voraussetzungen zur Testung von neuen Konzepten der biologisch individualisierten Hochpräzisionsstrahlentherapie mit dem Ziel der effektiveren Behandlung von Krebserkrankungen weiter verbessert.

Abstract

Current developments in PET/CT imaging address important requirements for the implementation of biological imaging for image-guided high-precision radiotherapy, i. e. high accuracy in co-registration and quantitative assessment of PET parameters. These developments include the time-of-flight technique, improved tomographic image reconstruction, further development of breathing-related movement and data processing. This provides an improved technical basis for the testing of novel concepts in biologically individualized high-precision radiotherapy aiming for better treatment of cancer patients.
