Zusammenfassung

Bisher wurden CT-Aufnahmen von einem rotierenden C-Bogen-System v. a. für die gezielte Unterstützung endovaskulärer und intraarterieller Interventionen verwendet. Mit einer neuen kombinierten 3D-C-Bogen-Navigationseinheit ist es jetzt aber auch möglich, perkutane Interventionen mit einem C-Bogen-System unter Schichtbild- und fluoroskopischer Kontrolle durchzuführen. In Studien wird über erfolgreiche CT-Bild-geführte Navigationen bei Vertebroplastien mit einem C-Bogen-System berichtet. Vorstellbar ist aber auch das Einbringen von Radiofrequenzsonden in Tumoren von Lunge und Leber, die bereits intraarteriell mit Lipiodol markiert wurden. Voraussichtlich können C-Bogen-CT-basierte Navigationssysteme in Zukunft komplexe Interventionen einfacher und sicherer machen und dabei gleichzeitig die Strahlenexposition reduzieren.

Abstract

So far C-arm CT images were predominantly used for a precise guidance of an endovascular or intra-arterial therapy. A novel combined 3D-navigation C-arm system now also allows cross-sectional and fluoroscopy controlled interventions. Studies have reported about successful CT-image guided navigation with C-arm systems in vertebroplasty. Insertion of the radiofrequency ablation probe is also conceivable for lung and liver tumors that had been labelled with lipiodol. In the future C-arm CT based navigation systems will probably allow simplified and safer complex interventions and simultaneously reduce radiation exposure.
