For this procedure, the patient is injected with contrast medium marked with a short-lived radioactive isotope. This enables both precise tumor localization ( CT ) and identification of metabolically active tumor fractions ( with the isotope marking areas of increased metabolic activity in the tumor or metastasis ) to be accomplished in a single session.

[...]
Hierbei wird dem Patienten ein Kontrastmittel injiziert, das mit einem kurzlebigen radioaktiven Isotop markiert ist, so dass in einer einzigen Untersuchung sowohl die genaue Tumorlokalisation ( CT ) als auch die tumoraktiven Anteile ( Isotop, durch die erhöhte Stoffwechselaktivität des Tumors bzw. der Metastase ) identifiziert werden.
