P156 Neuro coils and stents implants visualized through photon – counting computed tomography

<h3>Introduction</h3> The development of the photon counting technology has to the potential to expand the imaging possibilities of computed tomography. The new detectors calculate the energy of every single photon and provide CT Data with high spatial resolution without electric noise at lower radiation dose. This CT-imaging evolution has several advantages for neuroimaging. Here we focus on intracranial and extracranial implants such as stents and coils. <h3>Aim of Study</h3> To visualize endovascular intracranial and cervical implants with Photon Counting Computed Tomography. <h3>Methods</h3> <b>Ultra-high resolution CT-</b>Angiography and native head CT as well as spectral reconstruction after placement of neuro-endovascular implants. <h3>Results</h3> The imaging of the implants is very precise and reliable. <h3>Conclusion</h3> The results of the imaging of neuro-endovascular implants are precise and reliable. The UHR CT-angiography and spectral reconstructions might be beneficial to monitor treatment success. <h3>Disclosure of Interest</h3> no.
