研究目的:

探讨基于 mDixon 技术定量骨髓脂肪分数以勾画活性骨髓轮廓的方法,相较于传统将全骨盆作为危及器官,是否能优化骨髓的关键剂量-体积参数,并评估两套放疗计划的靶区覆盖均匀性与适形性,以及明确 mDixon 技术定量作为一种无创、精准的影像方法在勾画活性骨髓方面相比于传统全骨盆勾画方法的优势。  

Objectives of Study:

To explore whether the method of quantifying bone marrow fat fraction using the mDixon technique for delineating active bone marrow (ABM) contours can significantly reduce key dose-volume parameters of ABM compared with the conventional strategy of treating the entire pelvis as an organ at risk, to evaluate the target coverage uniformity and conformality between the two radiotherapy plans, and to demonstrate the advantages of the mDixon-based quantitative method as a non-invasive and precise imaging approach for ABM delineation over the conventional whole-pelvis contouring method.

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:

本研究采用epidata数据库进行数据管理。数据管理员在数据录入前应核查数据,发现问题及时通知研究者,要求研究者做出回答。各种疑问及解答的交换应 当采用疑问表(DRQ)形式。数据管理员在进行数据录入前,要了解观察表格各项目的内容及编码情况,将编码工作过程记录于编码本保存。数据录入与管理 由统计单位指定数据管理员负责。数据管理员应与研究者一起,按病例报告表中 各指标数值的范围和相互关系拟定数据范围检查和逻辑检查内容。原始病例报告 表在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等, 以备查考。经对数据库数据进行核对和评价,确认无误后,锁定数据库,锁定后 的数据文件不再做改动。由数据管理员导出分析数据库,交统计人员进行统计分 析。数据锁定之后发现的问题,经确认后在统计分析程序中进行修正。问题的确 认应有详细的记录文件。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study utilized the Epidata database for data management. Before data entry, the data manager should verify the data and promptly notify the researcher of any issues, requesting a response. Any queries and their corresponding responses should be exchanged using a Data Query Form (DRQ). Prior to data entry, the data manager must familiarize themselves with the content and coding of each item in the observation forms, documenting the coding process in a codebook for record-keeping.Data entry and management are the responsibility of the data manager designated by the statistical unit. The data manager should collaborate with the researcher to establish data range checks and logical checks based on the value ranges and interrelationships of the indicators in the case report forms.Once data entry and verification are completed as required, the original case report forms should be archived sequentially by identification number, accompanied by a retrieval index for future reference. After verifying and evaluating the database data to confirm accuracy, the database is locked, and no further modifications are permitted to the locked data files.The data manager then exports the analysis database and submits it to the statistician for statistical analysis. Any issues identified after the database is locked should be confirmed and corrected within the statistical analysis program, with detailed documentation of the confirmation process.
