确定在CT结肠造影（CTC）中除标准仰卧位和俯卧位序列外，还获得褥疮序列的比率和相关因素。CTC检查集中在一个机构阅读，但在三个不同的中心在6,380名成人进行了审查，以确定额外的褥疮系列的频率。根据研究适应症（初步筛查与不完全结肠镜检查诊断）、实践地点（学术与社区）、患者年龄、性别、体重指数（BMI）和时间变化分析结果。在所有临床试验机构，CT技术专家确定需要额外的褥疮系列，在选定病例中很少有放射科医生输入。CT技师在筛选时获得褥疮系列的频率为9.7%（578/5952），而结肠镜检查失败后为22.9%（98/428）（p<0.001）。学术中心的褥疮发生率（9.4%，550/5871）显著低于社区医院（34.6%，28/81）（p<0.001）。这一比率随着年龄的增长而逐渐增加，从50岁以下的5.0%增加到80岁以上的28.0%。男性和女性之间没有显着差异（10.3%对9.2%），但与BMI增加存在很强的相关性，BMI超过40时上升至>25%。学术中心存在显著的时间变化，季度率从0%到17%不等。在CTC进行第三个系列的频率根据适应症、临床试验机构、患者年龄、BMI和时间的不同而有很大差异。这些结果对临床实践具有重要意义，包括需要改进CT技术人员的培训和反馈。
To determine the rate and associated factors for acquiring a decubitus series at CT colonography (CTC), in addition to the standard supine and prone series. CTC examinations read centrally at one institution but performed at three different centers in 6,380 adults were reviewed to determine the frequency of an additional decubitus series. Results were analyzed according to study indication (primary screening versus diagnostic for incomplete colonoscopy), practice site (academic versus community), patient age, gender, body mass index (BMI), and temporal variation. At all sites, the CT technologist determined the need for an additional decubitus series, with infrequent radiologist input in select cases. The frequency for the CT technologist to obtain a decubitus series at screening was 9.7% (578/5952), compared with 22.9% (98/428) following failed colonoscopy (p<0.001). The decubitus rate at the academic center (9.4%, 550/5871) was significantly lower than the community hospitals (34.6% combined, 28/81) (p<0.001). The rate progressively increased with age, from 5.0% under age 50 to 28.0% over age 80. No significant difference was seen between men and women (10.3% versus 9.2%), but a strong correlation existed with increased BMI, rising to >25% for BMI over 40. Marked temporal variation existed at the academic center, with quarterly rates ranging from 0% to 17%. The frequency for performing a third series at CTC varies considerably according to indication, practice site, patient age, BMI, and time. These results have important implications for clinical practice, including the need for improved training and feedback for CT technologists.
