研究目的: |
1. 比较CDH胎肺与正常胎肺的影像组学特征差异,建立正常胎肺参考特征; 2. 在胎龄校正基础上分析组学特征与新生儿生存结局及呼吸循环相关结局(PAH、呼吸支持、通气时长、住院时长等)的关联; 3. 构建影像组学预测模型,并与传统指标(o/e LHR、o/e TFLV、PPLV、肝疝、疝囊等)对照及联合建模; 4. 开展多中心外部验证与稳健性评估,检验模型泛化能力与临床可用性。 |

|
Objectives of Study: |
1. To compare the radiomic features of fetal lungs in CDH with those in normal fetuses, and establish reference radiomic features for normal fetal lungs; 2. To analyze the associations between radiomic features and neonatal survival outcomes as well as respiratory and circulatory-related outcomes (including PAH, respiratory support, duration of ventilation, length of hospital stay, etc.) after adjusting for gestational age; 3. To construct a radiomic prediction model, compare it with traditional indicators (including o/e LHR, o/e TFLV, PPLV, liver herniation, hernia sac, etc.), and establish a combined prediction model; 4. To conduct multicenter external validation and robustness evaluation to verify the generalization ability and clinical applicability of the model. |

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: |
1. 数据采集和管理由两部分组成: (1) 病例记录表(CRF):依据统一数据字典设置字段,按研究编号(StudyID)填写母体/妊娠信息、影像学指标及结局信息; (2) 电子采集和管理系统(EDC/电子数据库):影像资料由PACS导出(胎儿MRI DICOM),临床与结局信息由电子病历系统提取后录入电子数据库。 2. 所有数据均去标识化管理,不包含姓名、身份证号、住址、电话等直接身份信息。 3. 牵头单位负责数据完整性与逻辑核对、版本管理与锁库;数据存放于受控存储空间,设置访问权限并定期备份。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data collection and management consist of two parts: (1) Case Report Forms (CRFs) based on a unified data dictionary, where each site records maternal/pregnancy information, imaging variables, and outcomes indexed by a study ID (StudyID); (2) an electronic data capture and management system (EDC/database), where fetal MRI DICOM images exported from PACS and clinical/outcome data extracted from the electronic medical record system are entered and managed. 2. All data are de-identified without direct identifiers. 3. The coordinating center performs completeness/logic checks, version control and database lock. Data are stored in a secure, access-controlled environment with regular backups. |
