Photon-Counting Computed Tomography for Evaluation of Coiled Intracranial Aneurysms.

ABSTRACT:

Background and purpose

Intracranial aneurysms treated with endovascular embolization often require surveillance imaging using digital subtraction angiography, an invasive, risky, and expensive procedure. Existing non-invasive imaging modalities (standard computed tomography [CT] or magnetic resonance [MR] angiography) are often unsatisfactory for evaluating treated aneurysm due to artifacts from embolization devices. The objective of the present study was to determine whether photon-counting computer tomography (PCCT) imaging parameters could be optimized to confer satisfactory imaging resolution in an anthropomorphic phantom of treated intracranial aneurysms.

Materials and methods

Phantom studies were performed using a model of the major intracranial arteries with appropria
