研究目的: |
基于平扫CT(NCCT)构建生成式AI模型(如GAN/Diffusion Model)生成虚拟增强CT,联合影像组学、临床指标(年龄、性别等)建立多模态融合网络,实现肾占位性病变(如肾癌/囊肿)的无创精准分类。 |
||||||||||||||||||||||
|
Objectives of Study: |
Based on non-contrast CT (NCCT), we aim to construct a generative artificial intelligence model (such as GAN/Diffusion Model) to generate synthetic contrast-enhanced CT. This will be integrated with radiomics features and clinical indicators (e.g., age, gender) to establish a multi-modal fusion network, achieving non-invasive and accurate classification of renal space-occupying lesions (such as renal cancer/cysts). |

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: |
本研究的数据记录与文件保存将严格遵循相关法规和伦理要求,确保数据的准确性和受试者的隐私安全。病例报告表(CRF)上有关受试者数据以受试者病案号的方式记录,受试者只能通过受试者编码进行识别,以避免直接暴露受试者身份信息。本研究采用电子数据采集系统(EDC)进行数据管理,从数据录入到源数据核查、质控数据的质疑与解答,再到数据锁定及导出的操作,均严格按照标准化流程执行。研究团队根据病例报告表(CRF)中的信息,通过EDC系统完成数据录入。随后,由独立的数据核查员对录入数据与原始病历记录进行比对,确保数据真实性和准确性。对于数据录入中的疑问或异常值,由数据管理员发起质疑,研究团队根据原始资料进行核实并提供解答。在确认数据无误后,各方签署数据库锁定申请表,由数据管理员对数据库进行锁定。锁定后的数据由数据管理员导出至分析数据库,交由统计人员进行统计分析。数据库锁定后,数据不可再进行编辑。若在统计分析过程中发现数据问题,需经研究团队确认后,通过统计分析程序进行修正。通过上述流程,本研究确保数据记录与管理的规范性、完整性和安全性,为研究结果的科学性和可靠性提供保障。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
All data recording and document preservation in this study will strictly comply with relevant regulations and ethical requirements to ensure data accuracy and participant privacy security. Subject information on the Case Report Forms (CRFs) is recorded using hospital identification numbers, and participants are identified only through unique subject codes to avoid direct exposure of personal identity. This study employs an Electronic Data Capture (EDC) system for data management. All steps—from data entry and source data verification to query management, quality control, and final database locking and export—are executed in strict accordance with standardized operating procedures.The research team enters data into the EDC system based on information from the CRFs. Subsequently, an independent data reviewer compares the entered data against the original medical records to ensure authenticity and accuracy. Any questions or outliers identified during data entry are raised as queries by the data manager. The research team then verifies these against source documents and provides clarifications. Once all data are confirmed as correct, authorized parties sign the database lock application, after which the data manager locks the database. The locked data are then exported by the data manager to an analysis-ready database and handed over to the statistician for statistical analysis.After the database is locked, no further edits to the data are permitted. If any data issues are discovered during statistical analysis, corrections may only be made through statistical programming after confirmation by the research team. Through the above procedures, this study ensures the standardization, completeness, and security of data recording and management, thereby safeguarding the scientific validity and reliability of the research outcomes. |
