Photon-counting CT to check intracranial stents

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective observational study evaluates the use of photon-counting detector CT angiography to assess intracranial stents in adults with prior intracranial arterial stents. By leveraging higher spatial resolution and reduced artifacts, the study aims to determine the technology's ability to visualize stent lumen and identify restenosis compared with standard imaging parameters. Participants are adults undergoing routine CTA follow-up, with imaging data collected for analysis. The investigation addresses whether this noninvasive modality can provide accurate, noninvasive surveillance and potentially reduce the need for invasive DSA in some cases.
