SZShenghua ZhuCSChelsea ScottBABaris Alten

Key Points

  • This research investigates the relationship between contrast persistence on multiphase CT angiography and ischemic stroke risk in carotid webs.
  • Examined contrast persistence metrics on multiphase CT angiography (CTA).
  • Focused on patients with carotid webs.
  • Utilized preliminary findings to suggest further validation studies.
  • Indicated a potential link between contrast persistence and local stasis within carotid webs.
  • Highlighted the need for larger cohorts to confirm initial findings.

Abstract

These findings suggest that contrast persistence metrics on multiphase CTA may reflect local stasis within CWs; however, results are preliminary and warrant validation in larger cohorts.
