P157 Dose comparison of CT in angio suite and CT photon – counting

<h3>Introduction</h3> The possibility of applying a CT scan during the operation enables the surgeon to control the positioning of the implants. The postoperative control of the implants with the photon counting technology gives the opportunity for a very precise imaging. These two techniques deliver a quite different dose to the patient. <h3>Aim of Study</h3> With this abstract, we would be able to see the relation between the doses of these two techniques in the same patient <h3>Methods</h3> Comparing the dose reports of the same patient with these two different CTs, first in the Angio suite and the second as post-OP. Comparing the image quality of these methods. <h3>Results</h3> The results of the imaging of neuro-endovascular implants are from both techniques reliable. The PCCT-angiography has a higher radiation dose but is also beneficial to monitor treatment success. <h3>Conclusion</h3> The CT in the Angio suite gives an immediate and accurate first impression of the surgery, despite of the lower dose. <h3>Disclosure of Interest</h3> no.
