A Novel Method for Determination of Thromboembolic Stroke Origin

Rupture of vulnerable carotid, vertebral, and intracranial arterial plaques results in thromboembolic stroke. Identification of these culprit lesions is an important component of post-stroke care. This study seeks to test the feasibility of NaF PET-CT to detect these plaques and alter patient care. Prior studies have shown a high degree of correlation between NaF PET+ lesions and high-risk plaque features on high resolution MRI, including mirocalcification, necrosis, and ulceration.
