Summary

With new developments that have taken place in the optimization of C-arm computed tomography (CACT) image acquisition and reconstruction, CACT image quality will be better than current standard-of-care CACT scan techniques used for neurovascular patients referred to endovascular treatment or diagnosis. As such, novel acquisition, filtration, artifact reduction and reconstruction techniques will be evaluated against the standard-of-care CACT approach.

Detailed description

This prospective observational study aims to enroll 50 patients diagnosed with various neurovascular conditions with the goal to compare the image quality of new types of head C-arm computed tomography (CACT) image scans with standard CACT scans, and also to compare these novel scans with standard CT scan image quality. These new scans use novel acquisition, filtration and reconstruction techniques compared to the standard-of-care CACT scans being used in the neuroangiography suite at the present time. Patient selection will be based on a suitability of patients for neuro-endovascular interventions in the neuroangiography suite. All research related activities will be done by study team members. The study patients are expected to follow their routine treatment schedule with the exception of 1 extra CACT scan while patient is receiving their standard treatment.
