颈动脉易损斑块破裂：早期诊断至关重要，超声造影是首选方法

Early and timely diagnosis of vulnerable plaques in the carotid artery that may rupture and cause embolism is crucial, as the presence of free-floating thrombi can lead to more severe strokes and has significant implications for reducing stroke-related morbidity and mortality. Carotid ultrasound imaging is a recommended diagnostic method, due to its simple and convenient operation, real-time monitoring, non-radiation exposure, and bedside examination.
