指标中文名:

客观参数

指标类型:

主要指标

Outcome:

Objective Parameters

Type:

Primary indicator

测量时间点:

患者入组后1个月

测量方法:

以椎旁肌肉的 SD 值作为背景噪声,计算HCC病灶、肝实质的SNR值、CNR值及LLR值(见公式1~3)。 SNR = CT病灶/肝实质÷SD病灶/肝实质 (1) CNR = (CT病灶-CT肌肉) ÷SD肌肉 (2) LLR = (CT病灶-CT肝实质) ÷SD肝实质 (3)

Measure time point of outcome:

One month after the patient was enrolled in the study

Measure method:

A experienced abdominal radiologist independently measured the noise and CT values of HCC lesions, hepatic parenchym and psoas muscle on CI and VMI40- VMI100, signal to noise ratio (SNR) and contrast signal to noise ratio (CNR) of lesions and hepatic parenchym, lesion-to-liver ratio (LLR) of lesions were calculated (Formula 1-3) . (1)SNR = CT lesion/parenchym ÷ SD lesion/parenchym(2)CNR = (CT lesion - CT muscle) ÷SD muscle(3)LLR = (CT lesion - CT parenchyma) ÷SD parenchyma

测量方法:

两名影像科医师,独立评价最佳单能量图像与CI图像中HCC病灶是否存在肝脏影像报告与数据报告系统2018版本标准中的主要征象(非环状动脉期高强化、非周边廓清、强化包膜)

Measure time point of outcome:

four month after the patient was enrolled in the study

Measure method:

Two same radiologists assessed in consensus the major features of HCC including nonrim APHE, nonperipheral washout, and enhancing capsule (present or not) on VMI40~VMI60 and CI in accordance with LI-RADS v2018. LI-RADS major features analysis.

测量方法:

两名影像医生使用5分法进行评价,从1分(图像质量差,病灶显示不清,病灶边界无法辨认,图像粗糙、颗粒感明显)到5分(图像质量好,病灶显示好,病灶边界清晰,图像清晰细腻)。以CI图像为参考基准,VMI图像评分可+2分(图像质量远优于)/+1分(优于)/+0分(相当)/-1分(差于)/-2分(远差于)

Measure time point of outcome:

four month after the patient was enrolled in the study

Measure method:

Two radiologists independently evaluated subjective scores on a 5-point likert scale of overall image quality on CIs and VMIs. According to previous studies, the score of overall images quality ranked from 1=severely impaired quality

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.
