Summary

Due to its advantageous nuclear physical properties iodine-123 is an excellent label for radiopharmaceuticals very well suited for measurements by γ-cameras and single-photon emission tomography. The development of 123I-radiopharmaceuticals should be based on a clear biochemical concept, reliable labelling procedures and careful pharmacokinetic studies in order to evaluate the physiological behaviour of the radioiodinated compounds being analogues of metabolic substrates. The development of 123I-labelled fatty acids and biogenic amines clearly proved the successful use of 123I for labelling compounds applied in medical diagnosis.

Zusammenfassung

Aufgrund seiner hervorragenden kernphysikalischen Eigenschaften stellt 123J ein ausgezeichnetes Radionuklid zur Markierung von Radiopharmaka dar, die somit sehr gut geeignet sind für Messungen mit herkömmlichen γ-Kameras oder mittels der Single Photon Emission Tomography (SPECT). Voraussetzung für die Entwicklung von 123J-Radiopharmaka sind klare biochemische Konzepte, zuverlässige Markierungsmethoden und pharmakokinetische Studien zur Ermittlung des physiologischen Verhaltens radiojodierter Verbindungen als Analoga metabolischer Substrate. Die Entwicklung 123J-markierter Fettsäuren und biogener Amine beweist sehr deutlich die erfolgreiche Verwendungsmöglichkeit von 123J zur Markierung von Verbindungen für die Anwendung in der nuklear-medizinischen Diagnose.
