研究目的: |
通过IVIM参数(D、D*、f)与DWI表观扩散系数(ADC值)结合,提高对结直肠良恶性病变的鉴别诊断能力。同时,明确IVIM参数与传统DWI参数在鉴别诊断中敏感性和特异性上的差异。为CRC的早期精准诊断、个体化治疗及预后管理提供更可靠的影像学依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
By combining the IVIM parameters (D, D*, f) with the apparent diffusion coefficient (ADC value) of DWI, the ability to differentiate between benign and malignant colorectal lesions is enhanced. At the same time, the differences in sensitivity and specificity between IVIM parameters and traditional DWI parameters in the diagnostic process are clarified. This provides more reliable imaging evidence for the early precise diagnosis, individualized treatment, and prognosis management of CRC. |

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: |
采集2025年8月至2026年8月期间,符合课题纳入标准的拟在本院手术的结直肠病变患者(约140例),使用联影MRI U790 3.0T 机器按照课题制定的执行标准进行相关影像数据扫描采集,同时收集配套的临床数据(患者年龄、性别、术后病理诊断结果)。将所收集的数据存于影像诊断专用软件系统Pacs中,同时备份刻盘所有影像数据。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
From August 2025 to August 2026, 140 patients with colorectal lesions who were scheduled for surgery in our hospital and met the inclusion criteria of the project were selected. Using the United Imaging MRI U790 3.0T machine, the relevant imaging data were scanned and collected according to the implementation standards set by the project. At the same time, the accompanying clinical data (patient's age, gender, and postoperative pathological diagnosis results) were also collected. The collected data were stored in the dedicated software system for image diagnosis and all the imaging data were backed up onto disks. |
