在美国每年近690,000例缺血性中风中，颈动脉粥样硬化性疾病约占25%。目前基于狭窄百分比的风险分层并未提供有关大多数个体中风实际风险的具体信息。前瞻性随机研究发现，只有10%到12%的无症状患者会在5年内出现症状性中风。对狭窄百分比的测量不能确定斑块的稳定性或成分。已有报道指出，与颈动脉斑块相关的脑缺血事件与斑块不稳定性密切相关。对回溯性研究的分析发现，斑块成分在风险分层中很重要。只有MRI有能力识别和测量颈动脉斑块的详细成分和形态，并提供比目前可用的其他技术更详细的信息。MRI可以准确检测颈动脉出血，MRI发现颈动脉出血与急性卒中相关。
Carotid therosclerotic disease causes approximately 25% of the nearly 690,000 ischemic strokes each year in the United States. Current risk stratification based on percent stenosis does not provide specific information on the actual risk of stroke for most individuals. Prospective randomized studies have found only 10 to 12% of asymptomatic patients will have a symptomatic stroke within 5 years. Measurements of percent stenosis do not determine plaque stability or composition. Reports have concluded that cerebral ischemic events associated with carotid plaque are intimately associated with plaque instability. Analysis of retrospective studies has found that plaque composition is important in risk stratification. Only MRI has the ability to identify and measure the detailed components and morphology of carotid plaque and provides more detailed information than other currently available techniques. MRI can accurately detect carotid hemorrhage, and MRI identified carotid hemorrhage correlates with acute stroke.
