Diagnostik von benignen und malignen Erkrankungen mit Knochenbeteiligung im Kindes- und Jugendalter mittels Knochenszintigrafie – ein Update

Zusammenfassung

Knocheneigene maligne Tumoren, Tumoren mit sekundärer Knochenbeteiligung sowie benigne Knochenerkrankungen im Kindes- und Jugendalter stellen den behandelnden Arzt oftmals vor große Herausforderungen hinsichtlich des weiteren Vorgehens. Dieser Artikel adressiert die Knochenszintigrafie als integralen Bestandteil der Diagnostik o.g. Erkrankungen. Neben Indikationen werden altersspezifisch vorbereitende Maßnahmen und angepasste Untersuchungsdurchführungen, Befundinterpretation sowie die Strahlenexposition dargestellt. Hierbei wird sowohl auf die planare Szintigrafie als auch auf räumlich aufgelöste Verfahren wie die SPECT bzw. SPECT/CT eingegangen.

Abstract

In pediatric and adolescent patients, primary bone tumors as well as metastatic bone disease or benign bone affections are often challenging to physicians concerning the further therapeutical work-up. This article focusses on radioisotope bone scan which represents a substantial part of the diagnostic work-up. Among indications age specific preparations and examinations as well as interpretation and radiation exposure will be discussed. Besides planar radioisotope bone scan-imaging the use of SPECT and SPECT/CT are presented.
