Eur Radiol: How to use differences in plaque characteristics and hemodynamics to predict the clinical prognosis of ischemic stroke?

Brain stroke is the second most common cause of death, ischemic stroke accounts for about 80% of all strokes.

High-resolution vascular wall MR (VW-MR) imaging is an effective non-invasive imaging method to characterize intracranial atherosclerotic plaques.

Recently, a study published in the journal European Radiology explored the differences in middle cerebral artery (MCA) plaques and hemodynamic characteristics in patients with ischemic stroke and transient ischemic attack (TIA), and established the deficiency Predictive model of blood stroke and nerve damage.

This study retrospectively analyzed 67 patients with acute ischemic events in the MCA region who underwent high-resolution vascular wall imaging from September 2016 to August 2018.

There were 45 cases in the stroke group and 22 cases in the TIA group.

Table 1 Plaque characteristics of stroke group and TIA group.

The figure uses the plaque characteristics and the antegrade score (AnS) to detect the superimposed receiver operating characteristic curve of the occurrence of stroke.

Table 2 Multiple linear regression analysis of ischemic stroke parameters.

    This study shows that longer plaque length, IPH, higher MCA plaque enhancement grade, lower AnS and larger Tmax> 6.
