Investigating plaque calcium in carotid arteries using advanced MRI

In Vivo Atherosclerotic Plaque Calcium Characterization for Predicting Ruptured Plaques

Jinan Military General Hospital · NCT03849521

What this trial studies

This observational study aims to explore the feasibility of using ultrashort echo time (UTE) MRI to enhance the imaging of carotid artery calcifications in vivo. By analyzing the correlation between UTE MRI findings and microcalcification in carotid plaques, the study seeks to identify characteristics of vulnerable atherosclerotic plaques that may lead to acute stroke. The research builds on previous findings that suggest active calcification processes in plaques could indicate higher risks for rupture and thrombosis. Patients referred for carotid endarterectomy or stenting will be enrolled, while those with certain exclusions will not participate.

Who should consider this trial

Good fit: Ideal candidates for this study are patients referred for carotid endarterectomy or stenting.

Not a fit: Patients with ferromagnetic implants, active medical devices, or those unable to undergo MRI due to claustrophobia will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved identification of high-risk atherosclerotic plaques, potentially reducing the incidence of acute strokes.

How similar studies have performed: While the approach of using UTE MRI for plaque characterization is relatively novel, previous studies have shown promise in imaging calcifications in atherosclerotic plaques.
