We aimed to assess the role of radiologists, cardiologists, and other medical and non-medical figures in cardiac magnetic resonance imaging (MRI) research in the last 34 years, focusing on first and last authorship, number of published studies, and journal impact factors (IF).
Articles in the field of cardiac MRI were considered in this systematic review and retrospective bibliometric analysis. For included studies, the first and last authors were categorized as cardiologists, radiologists/nuclear medicine physicians, medical doctors (MD) with specialties in both cardiology and radiology/nuclear medicine, and other MD and non-MD. Differences in the number of papers published overall and by year and institution location for the first and last author category were assessed. Mean IF differences between author categories were also investigated.
A total of 2053 articles were included in the final analysis. For the first authors (n = 2011), 52% were cardiologists, 22% radiologists/nuclear medicine physicians, 16% other MD, 10% other non-MD, and 1% both cardiologists and radiologists/nuclear medicine physicians. Similarly, the last authors (n = 2029) resulted 54% cardiologists, 22% radiologists/nuclear medicine physicians, 15% other MD, 8% other non-MD, and 2% both cardiologists and radiologists/nuclear medicine physicians. No significant differences due to institution location in the first and last authorship proportions were found. Average journal IF was significantly higher for cardiologist first and last authors when compared to that of radiologists/nuclear medicine physicians (both p < 0.0001).
Over 50% of studies in the field of cardiac MRI published in the last 34 years are conducted by cardiologists.
我们旨在评估放射科医生、心脏病专家以及其他医学和非医学人员在过去34年心脏磁共振成像（MRI）研究中的作用，重点关注第一作者和最后作者身份、发表研究的数量以及期刊影响因子（IF）。
本系统评价和回顾性文献计量分析纳入了心脏MRI领域的文章。对于纳入的研究，第一作者和最后作者被分类为心脏病专家、放射科医生/核医学医生、同时具备心脏病学和放射科/核医学专业的医生、其他医生以及非医生。评估了第一作者和最后作者类别在总体发表论文数量、按年份和机构所在地的发表论文数量差异。还研究了作者类别之间的平均IF差异。
最终分析共纳入2053篇文章。对于第一作者（n = 2011），52%为心脏病专家，22%为放射科医生/核医学医生，16%为其他医生，10%为其他非医生，1%为同时是心脏病专家和放射科医生/核医学医生。同样，最后作者（n = 2029）中，54%为心脏病专家，22%为放射科医生/核医学医生，15%为其他医生，8%为其他非医生，2%为同时是心脏病专家和放射科医生/核医学医生。未发现第一作者和最后作者比例因机构所在地而存在显著差异。与放射科医生/核医学医生相比，心脏病专家作为第一作者和最后作者时的平均期刊IF显著更高（均p < 0.0001）。
过去34年发表的心脏MRI领域研究中，超过50%是由心脏病专家开展的。
