Digitale Volumentomografie (DVT) des knöchernen Handskeletts: Erste Erfahrungen und Anwendungsmöglichkeiten

Zusammenfassung

Die digitale Volumentomografie (DVT) stellt eine neue Möglichkeit der Schnittbildgebung in der Handchirurgie dar. Die Methode hat in der letzten Dekade eine weite Verbreitung in der Kopf-Hals-Bildgebung gefunden und ist in diesem Bereich ein etabliertes Standardverfahren, für das eine, im Vergleich zur Computertomografie (MDCT), niedrigere Strahlenexposition beschrieben wird. Wir berichten über 24 Monate klinische Erfahrung mit dem Einsatz der Methode in einer handchirurgischen Universitätsklinik. Die DVT wird bezüglich ihrer Technik sowie ihrer klinischen Eignung anhand von exemplarischen Falldarstellungen vorgestellt und evaluiert. Weiterhin werden ihre Vor- und Nachteile diskutiert und in den Kontext der aktuellen Literatur gesetzt.

Abstract

During the last decade, DVT (digital volume tomography) imaging has become a widely used standard technique in head and neck imaging. Lower radiation exposure compared to conventional computed tomography (MDCT) has been described. Recently, DVT has been developed as an extremity scanner and as such represents a new imaging technique for hand surgery. We here describe the first 24 months experience with this new imaging modality in hand and wrist imaging by presenting representative cases and by describing the technical background. Furthermore, the method’s advantages and disadvantages are discussed with reference to the given literature.
