|
Objectives of Study: |
1. Establish an automatic segmentation model of perivascular fat around the carotid artery based on CTA to achieve automatic extraction of perivascular fat image features; 2. Develop a postoperative ischemic risk prediction model for carotid artery stenosis (CAS) based on multi-modal feature fusion; 3. Build a prospective cohort of carotid artery stenosis (CAS) to verify the efficacy of the postoperative ischemic risk prediction model for carotid artery stenosis (CAS). |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A dedicated case data management and follow-up system will be established, with two data entry clerks independently standardizing the data entry. A designated person will be responsible for management. Specialized data entry and data management procedures will be developed. All necessary supporting conditions for the implementation of the project are in place. Members of this research group have collaborated on multiple projects and have a strong foundation and experience in cooperation, which can ensure the normal implementation of the project. The project leader can effectively fulfill the management responsibilities of the project and has already formed a multi-disciplinary collaborative research team with a complete management system. |
