Abstract

The introduction of flat-panel detectors in modern angiographic C-arm systems makes it possible to acquire CT-like images in the angiographic suite (flat-panel CT; FD-CT). In this review, after a short technical introduction of FD-CT including the discussion of the advantages and disadvantages of this new imaging modality, the most commonly and best evaluated indications for FD-CT will be described. FD-CT has become an important adjunctive imaging modality in neurointerventional procedures and embolizations, especially during liver embolization. Another attractive indication for FD-CT is musculoskeletal interventions. FD-CT may provide important additional information in complicated peripheral vascular interventions and stent-graft procedures. FD-CT has a broad spectrum of possible applications, which finally depends on the experience and innovative thinking of the operator. However, it has to be kept in mind that FD-CT causes additional radiation exposure. Roughly, it can be assumed that currently one FD-CT sequence causes at least the same radiation exposure as one spiral CT sequence of the corresponding body region.
