研究目的:

使用临床常规MRI设备采集T1WI、T2WI、DWI/ADC及动态增强序列(增强钆基对比剂按各中心常规),并应用Grounded-Liver AI软件完成肝脏病变VQA诊断、报告生成与病变定位。提升AI辅助肝脏病变诊断准确性,实现恶性病变早期干预、降低治疗后复发率及增加患者无进展生存期。  

Objectives of Study:

Clinical routine MRI equipment was used to acquire T1WI, T2WI, DWI/ADC and dynamic enhancement sequences (the enhanced gadolinium-based contrast agent was applied according to the routine of each center), and the Grounded-Liver AI software was used to complete the VQA diagnosis of liver lesions, report generation and lesion localization. This study improves the accuracy of AI-assisted liver lesion diagnosis, enables early intervention for malignant lesions, reduces the recurrence rate after treatment and increases the progression-free survival period of patients.

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:

病例记录表 (CRF):创建?个标准化的肝脏病变记录表,包含所有需要收集的病例信息字段。这可能包括患者的基本信息、MRI检查记录、生化指标、病理结果这段、临床病史、最终临床诊断结果等。确保病例记录表的设计符合研究?的和数据采集要求。字段应清晰明了,便于填写和审核。为每位患者创建?个唯?的标识符,以便在整个数据集中唯?标识每个病例。提供清晰的填写说明,确保研究?员能够正确理解和录?信息。 电?采集和管理系统 (EDC):在EDC系统中设置相应的病例记录表,确保系统能够按照CRF的设计进?数据管理。

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

Case Record Form (CRF): Develop a standardized record form for liver lesions, including all the fields that need to be collected for the case information. This may include the patient's basic information, MRI examination records, biochemical indicators, pathological results, clinical history, final clinical diagnosis, etc. Ensure that the design of the case record form is in line with the research purpose and data collection requirements. The fields should be clear and easy to fill in and review. Create a unique identifier for each patient to uniquely identify each case throughout the data set. Provide clear instructions for filling in to ensure that researchers can correctly understand and enter the information. Electronic Collection and Management System (EDC): Set up the corresponding case record form in the EDC system to ensure that the system can manage data according to the design of the CRF.
