颈动脉斑块内出血的高分辨率MR成像临床应用与技术进展

The clinical application and technology progress of highresolution MRI in carotid intraplaque hemorrhage

脑卒中是目前人类伤残死亡的首要原因,而颈动脉易损斑块(vulnerable plaque)与脑卒中的发生密切相关,其中斑块内出血是易损斑块的一个重要特征。早期识别颈动脉粥样斑块成分对预防和控制缺血性脑卒中至关重要。高分辨率MRI具有高组织分辨率、无创、可重复性的优点,是识别颈动脉血管形态和量化颈动脉斑块成分的有效方法。近年来,快速、准确地诊断斑块内出血的MRI技术不断地发展。作者就高分辨率MRI对颈动脉斑块内出血的临床应用及技术进展方面作一篇全面的综述。

Stroke is a leading cause of human death and disability, and carotid vulnerable plaque is closely related to the occurrence of stroke, intraplaque hemorrhage is an important feature of vulnerable plaque. Early identification of carotid plaque composition is crucial for the prevention and control of ischemic stroke. High-resolution MRI with advantages of high tissue resolution, non-invasiveness and repeatability, is an effective method to identify carotid vascular morphology and quantify carotid plaque composition. In recent years, MRI technology to diagnosing intraplaque hemorrhage rapidly and accurately is develop continuingly. In this paper, we made an overall review on MRI clinical applications and technical progress incarotid intraplaque hemorrhage.
