By using multi-contrast high-resolution MRI, we prospectively studied whether carotid plaque characteristics can predict acute lower limb arterial thrombosis (ALLAT). In the present study, each carotid atherosclerotic patient with and without ALLAT underwent a carotid MRI examination on a 3.0-T MRI scanner. Our findings showed that the presence of fibrous cap rupture was the strongest independent predictor for ALLAT.
