Summary

Hardened plaque located in the carotid arteries can cause stroke or transient ischemic attack (TIA). This type of plaque is linked to unstable free-floating thrombi (FFT). FFT are blood clots that form in a blood vessel, and are at the highest risk for travelling within the bloodstream and causing strokes. Physicians are able to see this type of plaque with computed tomographic angiography (CTA) but FFT look very similar to stable types of plaque that do not require urgent treatment.

Distinguishing between these plaques is important because it affects the choice and urgency of treatment that patients receive.

The researchers have found a promising visual marker on CTA scans. The goal of this study is to determine if this visual marker seen on CTA scans will help to distinguish FFT plaque from stable plaque.

Conditions

  • Stroke
  • Transient Ischemic Attack

Interventions

RADIATION

Computed Tomographic Angiogram

1 additional non-clinical CTA per patient enrolled in the study. The estimated radiation risk from a single CTA of the neck and brain is approximately 3.6 millisieverts (mSv), an exposure similar to a single airplane flight across Canada.
