Association between signal hyperintensity on T1-weighted MR imaging of carotid plaques and ipsilateral ischemic events.

Abstract

Carotid plaque signal hyperintensity on T1WI is strongly associated with previous ipsilateral ischemic events, persisting over a period of months, and may indicate risk of subsequent events. Larger clinical trials are warranted to clarify associations between signal hyperintensity and risk of subsequent cerebral ischemic events.
