研究目的:

比较光子计数CT 超高分辨率 和标准分辨率两种CCTA扫描方式,以分析何种扫描方式更合适,解决日常CCTA检查中,超高分辨率 和标准分辨率扫描方式如何取舍的问题;探索超高分辨率 和标准分辨率两种CCTA扫描方式对检测高风险斑块以及评估冠状动脉狭窄的潜在影响。  

Objectives of Study:

Compare the two CCTA scanning modes of ultra-high resolution and standard resolution in photon counting CT to analyze which scanning mode is more suitable and whether it has universality, and solve the problem of how to choose between the UHR and SR scanning modes in daily CCTA examinations; explore the potential impacts of the two CCTA scanning modes of ultra-high resolution and standard resolution on the detection of high-risk plaques and the assessment of coronary artery stenosis.

随机方法(请说明由何人用什么方法产生随机序列):

这项平行设计、按年龄分层的随机对照试验由生物统计学家李艳芬实施。分组序列随机数使用微软 Excel 2023 软件通过计算机生成,主随机种子为 20240401(适用于年龄小于 60 岁的参与者),次随机种子为 20240402(适用于年龄大于等于 60 岁的参与者)。奇数编号和偶数编号分别被分配给超高分辨率(UHR)方案和标准分辨率(SR)方案。研究设计者不参与招募和成像工作,放射科医生对成像方案和临床数据并不知情。

Randomization Procedure (please state who generates the random number sequence and by what method):

The parallel-group, age-stratified randomized controlled trial was carried out by a biostatistician Yanfen LI. The allocation sequence was computer-generated using Microsoft Excel 2023 with primary seed 20240401 (for participants age < 60) and secondary seed 20240402 (for participants age ≥ 60 years). Odd/even numbering is assigned to UHR and SR protocols, respectively. The designers had no contact with recruitment/imaging, radiologists were blinded to acquisition protocol and clinical data.

是否公开试验完成后的统计结果:

公开/Public

盲法:

开放标签 由于本质上无法对 CT 分辨率参数设盲,这是一项开放标签的随机试验。不过,终点事件判定人员在图像分析过程中对分组情况不知情。

Blinding:

Open label This was an open-label randomized trial due to the inherent inability to mask CT resolution parameters. However, endpoint adjudicators were blinded to group allocation during image analysis.

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。采用 ResMan 作为数据采集的电子平台。

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, etc.), information related to the intervention measures (such as scanning parameters, etc.), as well as adverse events and other contents. 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. ResMan is adopted as the electronic platform for data collection.
