测量指标:

Outcomes:

指标中文名:

图像质量评分

指标类型:

主要指标

Outcome:

Image Quality Scoring.

Type:

Primary indicator

测量时间点:

检查结束后1天

测量方法:

由两名具有10年工作经验的放射科技师,在对分组不清楚的条件下使用统一的5分制Likert量表(1 = 无法诊断,5 = 极佳)对所有图像进行集中评估,有争议处商量确定

Measure time point of outcome:

1 day after the examination.

Measure method:

A centralized assessment of all images was performed by two radiologic technologists with 10 years of work experience, using a uniform 5-point Likert scale (1 = non-diagnostic, 5 = excellent) under conditions where the grouping was unclear. Any disagreements were resolved through discussion.

指标中文名:

随机方法(请说明由何人用什么方法产生随机序列):

统计人员将“声学预适应干预准备”和“标准准备”分别定义为A组和B组。准备两套完全一致的外包装信封,一套内装声学预适应干预准备内容(A),另一套装一般准备内容(B)。研究协调员打开密封信封,获得该受试者的组别分配(以A组为例)。

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

Statisticians defined the "acoustic pre-adaptation intervention preparation" and "standard preparation" as Group A and Group B, respectively. Two sets of completely identical outer packaging envelopes were prepared, one containing the acoustic pre-adaptation intervention preparation content (A), and the other containing the general preparation content (B). The research coordinator opened the sealed envelope and obtained the group assignment for that subject (taking Group A as an example).
