Theory and concept of extraction involving invasive as well as non-invasive procedures to assess the first-pass extraction of tracers based on the indicator dilution technique are discussed. The experimental result of a noninvasive method using a gamma scintillation camera-computer system of firstpass pulmonary extraction of N-lsopropyl-123l-p-lodoamphetamine (123I-IMP) are also discussed.

Zusammenfassung

Theorie und Konzept der Bestimmung der first-pass Extraktion auf der Basis der Indikatorverdünnungsmethode werden sowohl für invasive als auch für nichtinvasive Verfahren diskutiert. Die First-pass Lungenextraktion von N-Isopropyl-123J-p-Jodamphetamin (123J-IMP) wird anhand experimenteller Daten mit einer Gammakamera und Rechner besprochen.
