Zusammenfassung
Nuklearmedizinische tomografische Verfahren wie die Positronen-Emissions-Tomografie (PET) und Single-Photonen-Emissions-Computertomografie (SPECT) werden in einem quantitativen Setting genutzt (z. B. die PET) bzw. sind, wie im Fall der SPECT, aufgrund der Erfordernisse nuklearmedizinischer Therapien an eine bildbasierte Dosimetrie, als quantitative bildgebende Modalität zu etablieren. Für die quantitative Analyse der bereitgestellten Bilddaten existieren unterschiedliche Konzepte. Ausgehend von der Quantifizierung dynamischer Aufnahmen mittels der Zeitaktivitätskurve wird für die kinetische Modellierung die Patlak-Methode vorgestellt. Verschiedene Methoden zur Auswertung statischer PET-Messungen, wie der Standardized Uptake Value (SUV) und das Standardized Uptake Ratio (SUR), werden diskutiert. Für die SPECT werden exemplarisch verschiedene methodische Entwicklungen auf dem Weg zur quantitativen Modalität adressiert.
Abstract
Nuclear medicine tomographic imaging techniques such as positron emission tomography (PET) and single photon emission computed tomography (SPECT) are used in a quantitative setting (e. g., PET) or, as in the case of SPECT, must be established as a quantitative imaging modality due to the requirements of nuclear medicine therapies for image-based dosimetry. Different concepts exist for the quantitative analysis of the imaging data provided. Starting with the quantification of dynamic images using the time-activity curve, Patlak's method is presented as an established method for kinetic modeling. Different methods for the evaluation of static PET measurements like the standardized uptake value (SUV) as well as the standardized uptake ratio (SUR) will be discussed. For SPECT, different methodological developments on the way to quantitative modality are addressed as examples.
