研究设计:

连续入组 

Study design:

Sequential 

研究目的:

1、探讨斑块特征、PVAT能谱多参数与症状性斑块的相关性; 2、筛选预测症状性斑块的独立危险因素并构建预测模型; 3、比较不同模型临床效能,从而探究PVAT能谱多参数能否在传统风险参数的基础上提升预测性能。  

Objectives of Study:

1. To investigate the correlation between plaque characteristics, parameters of PVAT from spectral CT, and symptomatic plaques. 2. To screen independent risk factors for predicting symptomatic plaques and construct a prediction model. 3. To compare the clinical efficacy of different models, thereby exploring whether multi-parameters of PVAT from spectral CT can improve predictive performance beyond traditional risk parameters.
