Objectives of Study: |
To construct and validate an ultrasound radiomics-based risk prediction model for patent foramen ovale (PFO)-related cryptogenic stroke in young and middle-aged adults (aged 18–60 years), thereby enabling precise identification of high-risk individuals and guiding clinical decision-making to avoid overtreatment or undertreatment. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据来源于本院PACS及电子病历系统。超声图像以DICOM或JPG格式导出,临床数据由双人核对录入加密数据库。所有数据去标识化处理,存储在科室专用服务器,由专人管理,定期备份。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data came from the hospital's PACS and EMR systems. Ultrasound images were exported as DICOM/JPG. Clinical data were double-entered into an encrypted database. All data were de-identified, stored on a dedicated server, managed by assigned staff, and regularly backed up. |
