Description
Objective To demonstrate the feasibility of intravenous Flat Detector CT Angiography (FD-CTA) for visualisation of intracranial Flow Diverting Devices. Flow Diverting Devices are used increasingly for treatment of intracranial aneurysms. A close follow up is necessary because it becomes obvious that a significant proportion of aneurysms treated with these devices remain patent. A minimally invasive method is highly desirable. Methods In two patients treated with flow diverters a Flat Detector CT (FD-CT) with intravenous contrast medium application was performed. Post-processing was performed using commercially available software. Results In both patients the lumen of the device and the lumen of the aneurysm could be clearly evaluated. Some beam hardening artefacts due to the marker wires of the device were obvious. Conclusion Flat Detector CT with intravenous contrast material application to evaluate flow-diverting devices seems to be feasible. Further studies are necessary to perform comparative evaluation of FD-CTA with angiography and other techniques like MRA or conventional CT angiography.
