It is currently unknown how many publications in the medical imaging literature are retracted and for which reasons. The purpose of this study was to perform an updated analysis on retracted medical imaging publications using the Retraction Watch Database.
The Retraction Watch Database was searched for all retracted publications in the subject category "Radiology/Imaging" (no beginning date limit, search update until April 27, 2022). Reasons for retraction were extracted using standardized coding taxonomy. The number of citations per retracted publication was determined. Spearman's rho was used for statistical analysis.
192 retractions, originally published between 1984 and 2021, were included. Most retractions originated from China (31.3%), the United States (12.5%), Japan (7.3%), and South Korea (6.3%). The number of retractions increased over the years, especially since 2000 (Spearman's rho=0.764, p <0.001). Delay between original publication and retraction ranged from 0 days to 14 years and 3 months (median of 11 months). Most common reasons for retraction were duplication of article (7.1%), plagiarism of article (6.8%), concerns/issues about data (5.4%), investigation by company/institution (4.5%), and forged authorship (4.0%). Scientific misconduct was deemed present in 107 of 192 retracted articles (55.7%). Retracted articles (of which 138 were listed in Web of Science) received a median of 2 citations (range 0-148, IQR 5).
The number of retracted medical imaging publications continues to increase over time, which could indicate that more compromised research has either been published or discovered. Scientific misconduct was the main cause for retraction.
目前尚不清楚医学影像学文献中有多少出版物被撤回，以及撤回的原因。本研究旨在使用撤回观察数据库对撤回的医学影像学出版物进行更新分析。
在主题类别“放射学/影像学”中（无起始日期限制，搜索更新至 2022 年 4 月 27 日），从撤回观察数据库中搜索所有撤回的出版物。使用标准化编码分类法提取撤回的原因。确定每篇撤回出版物的引用次数。采用斯皮尔曼等级相关系数进行统计学分析。
共纳入 192 篇原始发表时间在 1984 年至 2021 年之间的撤回论文。大多数撤回论文来自中国（31.3%）、美国（12.5%）、日本（7.3%）和韩国（6.3%）。撤回数量逐年增加，尤其是自 2000 年以来（斯皮尔曼等级相关系数=0.764，p<0.001）。原始出版物与撤回之间的时间间隔从 0 天至 14 年零 3 个月不等（中位数为 11 个月）。撤回的最常见原因是文章重复（7.1%）、文章抄袭（6.8%）、对数据的担忧/问题（5.4%）、公司/机构的调查（4.5%）和伪造作者身份（4.0%）。在 192 篇撤回的文章中，有 107 篇（55.7%）被认为存在科学不端行为。撤回的文章（其中 138 篇在 Web of Science 中列出）的引用中位数为 2 次（范围 0-148，IQR 5）。
随着时间的推移，撤回的医学影像学出版物数量持续增加，这可能表明有更多的有问题的研究被发表或被发现。科学不端行为是撤回的主要原因。
