研究目的: |
脑卒中事件具有发病率高、致残率高及死亡率高的特点,动脉粥样硬化是缺血性脑卒中的最常见病因,尽管多数研究证实脑卒中发生率与血管狭窄程度呈正相关,但轻度管腔狭窄的病人脑卒中发生率也在上升,因此研究颈内动脉易损斑块的成分尤为重要。无创性斑块成像技术飞速发展,对颈动脉粥样硬化的诊疗提供了非常有利的手段,能够精准快速地识别易损斑块,人工智能在CT、MRI及超声对颈动脉易损斑块特征已有很多研究,但是对颈动脉斑块进行风险分层方面,尚未有研究将能谱 CT及MRI定量参数整合入机器学习模型中,临床未广泛使用,仍需要进行大规模的前瞻性纵向研究。 |

Objectives of Study: |
Stroke events are characterized by high incidence, high disability rate, and high mortality rate. Atherosclerosis is the most common cause of ischemic stroke. Although most studies have confirmed a positive correlation between the incidence of stroke and the degree of vascular stenosis, the incidence of stroke is also increasing in patients with mild luminal stenosis. Therefore, it is particularly important to study the components of vulnerable plaques in the internal carotid artery. Non-invasive plaque imaging technology has developed rapidly, providing very favorable means for the diagnosis and treatment of carotid atherosclerosis. It can accurately and quickly identify vulnerable plaques. There have been many studies on the characteristics of carotid vulnerable plaques by artificial intelligence in CT, MRI, and ultrasound. However, in terms of risk stratification of carotid plaques, no study has integrated the quantitative parameters of spectral CT and MRI into machine learning models yet. It has not been widely used in clinical practice and still requires large-scale prospective longitudinal studies. |
