研究目的: |
主要目的:采用双层探测器能谱CT能谱成像,评价、优选原发性肝癌病灶的最佳单能量图; 次要目的:比较常规CT图像(conventional images, CIs)与最佳单能量图像对原发性肝癌病灶主要征象检出率。 |

|
Objectives of Study: |
To evaluate image quality of virtual monoenergetic images (VMIs) in early hepatocellular carcinomas (HCC) on dual-layer spectral detector CT (DLSCT), and to compare major imaging features (MFs) of HCC on conventional images (CIs) and optimal VMIs based on Liver Imaging Reporting and Data System version 2018 (LI-RADS v2018). |

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: |
通过提取入组受试者常规临床诊疗记录获取这项研究的数据。要求研究者在整个监测期间根据原始病历记录中的信息输入到研究的电子病例报告表(eCRF)和或记录表。研究者必需保证数据真实、完整、准确; 研究记录做任何更正时只能划线,旁注改后的数据,说明理由,由研究者签名并注明日期,不得擦涂、覆盖原记录;实验室检查项目齐全。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data for this study was obtained by extracting the routine clinical diagnosis and treatment records of the enrolled subjects. The researchers were required to input the information from the original medical records into the electronic case report form (eCRF) and/or record sheet of the study during the entire monitoring period. The researchers must ensure that the data is true, complete and accurate. Any corrections to the research records can only be made by drawing lines, annotating the revised data, stating the reason, signing by the researcher and indicating the date. It is not allowed to erase or cover the original records; all laboratory examination items must be complete. |
