研究目的:

肥胖常导致非对比剂冠状动脉磁共振血管成像图像质量欠佳,这主要源于传统膈肌导航对呼吸运动补偿效果的减弱。本研究旨在评估相较于膈肌导航,左心室导航技术是否能够改善CMRA图像质量,特别是在体重指数升高的患者群体中。  

Objectives of Study:

Obesity often results in suboptimal image quality in non-contrast coronary magnetic resonance angiography, primarily because conventional diaphragmatic navigation is less effective at compensating for respiratory motion. This study aims to evaluate whether left ventricular navigation technology improves coronary magnetic resonance angiography image quality compared with diaphragmatic navigation, particularly in patients with elevated body mass index.

测量指标:

Outcomes:

指标中文名:

Coronary MRA 扫描成功率

指标类型:

主要指标

Outcome:

Scan Success Rate of Coronary MR angiography

Type:

Primary indicator

测量时间点:

试验完成后

测量方法:

评估冠脉 MRA 图像质量,采用国际公认的冠脉 MRI 图像质量评分标准(Likert 评分 1-5 分:1分:不可见; 2分:差/不佳; 3分:可接受/一般;4分:好/良好;5分:优秀)。由 2 名经验丰富的心血管影像医师双盲评分,分歧时通过第三方仲裁确定最终结果。

Measure time point of outcome:

After the trial is completed

Measure method:

The image quality of coronary MRA was assessed using an internationally validated coronary MRI quality scoring scale (a 5-point Likert scale: 1, non-visible; 2, poor; 3, acceptable; 4, good; 5, excellent). Two experienced cardiovascular radiologists independently scored the images in a blinded manner. Any discrepancies were resolved by a third arbiter to reach a final consensus.

冠脉成像信噪比

指标类型:

主要指标

Outcome:

Signal-to-Noise ratio of coronary MRA

Type:

Primary indicator

测量时间点:

试验完成后

测量方法:

通过在冠状动脉各节段绘制感兴趣区,测量冠状动脉和心肌的信号强度(SI)及标准差(SD)。心肌的 SD 作为背景噪声。冠状动脉各节段的表观信噪比(apparent SNR)和表观对比噪声比(apparent CNR)通过以下公式计算:表观 SNR = 冠状动脉 SI / 心肌 SD。

Measure time point of outcome:

After the trial is completed

Measure method:

Signal intensity (SI) and standard deviation (SD) of the coronary artery were measured by drawing regions of interest at each segment of the coronary artery and septal myocardium. The SD of the myocardium served as background noise. The apparent SNR and apparent CNR of each segment of the coronary artery were measured by the following formulas: apparent SNR = SI coronary artery / SD myocardium.

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:

设计了详细的 CRF,用于记录患者的基本信息(如年龄、性别、病史等)、干预措施相关信息(如扫描参数等)、以及不良事件等内容。CRF 的设计遵循研究方案和相关法规要求,确保数据的完整性和准确性。在数据采集过程中,由经过培训的研究人员按照统一的标准和规范,在患者就诊、检查、随访等各个环节及时填写 CRF,确保数据的及时性和真实性。

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

A detailed Case Record Form (CRF) has been designed to record patients' basic information (such as age, gender, medical history), intervention-related information (such as scanning parameters), adverse events, and other details. The design of the CRF complies with the research protocol and relevant regulatory requirements to ensure the integrity and accuracy of the data. During the data collection process, trained researchers fill in the CRF in a timely manner according to the unified standards and specifications at various stages, such as patients' visits, examinations, and follow-ups, ensuring the timeliness and authenticity of the data.
