Ziele: To evaluate the possibilities in applying a novel algorithm to correct for beam hardening artifacts caused by metal implants in computed tomography performed on a flat panel equipped c-arm angiography system (FP-CT). Methode: 35 datasets of cerebral FP-CT acquisitions (XperCT, Allura Xper FD 20/20, Philips) with present implants (32 patients; 27 FP-CT after coil-embolization; 8 after aneurysm clipping, these with intravenous application of contrast media) have been reconstructed applying smooth (soft tissue) and sharp (implant) kernels with and without a novel reconstruction filter for metal artifact correction, resulting in high-resolution isotropic datasets (edge length: 0.15 mm for sharp kernel and 0.3 mm for smooth kernel, respectively). Image viewing was performed in multiplanar reformations (MPR) in both average and maximum intensity projection (MIP) mode, sharp kernel images additionally in 3D MIP and 3D volume rendering (VR) on a dedicated radiological workplace (PACS IW, GE). Two independent radiologists performed image rating following a defined scale in direct comparison of the image data with and without metal artifact correction, weighted kappa statistics were calculated. Ergebnis: Inter-rater agreement was at least substantial in all regards. Soft tissue image quality at the level of the implants was substantially improved; the additional metal artifact correction algorithm did not induce relevant falsification of the data. In addition, two factors were identified to be having an influence on the quality of the results: Firstly, volume/amount of the implants; secondly, orientation of a non-spherical implant relatively to the plane of acquisition. Schlussfolgerung: Adding metal artifact correction to FP-CT may in future help to spread the applicability of this technique, especially regarding non-invasive follow-up after clipping or coil embolization of intracranial aneurysms with FP-CT with intravenous application of contrast media.
