Zusammenfassung

Die Darstellung von Hirntumoren war die Hauptaufgabe nuklearmedizinischer Methoden in der Neurologie, bevor bessere bildgebende Verfahren — Computer-Tomographie und KernspinTomographie — zur Verfügung standen, mit denen Isotoptechniken bezüglich räumlicher Auflösungsvermögen, Spezifität der Befunde und Zeitaufwand pro Untersuchung nicht konkurrieren konnten. Auch für onkologische Anwendungen liegt die Stärke der PET nicht in der Abbildung der morphologischen Veränderungen im Gehirn, sondern in der Darstellung des veränderten Stoffwechsels, der veränderten Verteilung und des spezifischen Abbaus von Pharmaka und der selektiven Inkorporation von Stoffwechselsubstraten im Tumorgewebe.

Abstract

The detection of brain tumors was the main task of nuclear medical methods in neurology until improved imaging techniques — computed tomography and magnetic resonance tomography imaging — became available; isotope techniques cannot compete with these in terms of spatial resolution, specificity of findings, and time required per investigation. For oncological applications also, the strength of PET does not lie in the imaging of the morphological changes in the brain, but in the demonstration of the changed metabolism, altered distribution, and specific degradation of drugs and selective incorporation of metabolic substrates into tumor tissue.
