Top Publications in Radiology, 2020

Published Online:https://doi.org/10.1148/radiol.2020209016

“Top” lists are part our current culture—scorecards of our lives, professions, and society. Top hospitals in the country, top destinations to visit, top products to buy, books to read, or shows to watch. The utility of top lists is to help us avoid missing key information. With thousands of medical articles published each year, there is utility in lists for scientific journals as well.

The COVID-19 pandemic has changed everything, and its impact is strongly reflected in our top rankings of journal articles. For this journal, the very first submission that we received in relationship to COVID-19 was a new type of article for Radiology that we started 2018 called Images in Radiology. The concept of “Images” was that of a showcase for state of the art in our field—radiology eye candy. The concept was also partly from frustration, seeing some of the best “images” from my radiology colleagues published not in Radiology, but in the New England Journal of Medicine (NEJM). “Images in Clinical Medicine” in NEJM shows classic radiologic images. The Radiology editorial board took a different tack—Images in Radiology was designed to illustrate the unique combination of beauty and information that has attracted many of us to our discipline (see https://bit.ly/3ivcBba for all of the “Images” that we have published).

Images in Radiology has grown to be extremely popular with authors from around the world. Dr Mark Schiebler on our editorial board has guided this section. Beyond his expertise in cardiothoracic imaging, Dr Schiebler has an eye for compelling visual representations of disease using new imaging technologies.

In January of 2020, the entire world began to hear of a previously undescribed infectious lung disease in Wuhan, China. On January 29, 2020, we received an Images in Radiology submission from Lanzhou, China (1). Lanzhou, a city of more than 3 million people along the banks of the Yellow River, is more than 1100 kilometers (more than 700 miles) from Wuhan—15 hours by car. The patient in the January 29 “Images” submission worked in Wuhan, but had traveled to Lanzhou 6 days before presentation to the hospital in Lanzhou. Real-time fluorescence polymerase chain reaction of the patient’s sputum was positive for the 2019 novel coronavirus (2019-nCoV) nucleic acid.

Radiology published the Images in Radiology report entitled “CT Imaging of the 2019 Novel Coronavirus (2019-nCoV) Pneumonia” on January 31, 2020 (1). This case became the first CT image of COVID-19 that was broadly circulated in the radiologic community. The “Images” submission was not “state-of-the-art” like prior publications in the same category. It was simply two axial images of the chest. Yet, this “Images” case was something even more valuable—new knowledge. The characteristic peripheral ground-glass opacities with subpleural sparing of COVID-19 pneumonia were beautifully shown by the authors, Drs Lei, Li, Li, and Qi. The authors added a slight touch for nonradiologists—red boxes bilaterally over the lungs to highlight the lung opacities. The power of radiologic imaging is demonstrated in this simple case: their first Images in Radiology of COVID-19 pneumonia has been downloaded more than 130 000 times and cited 97 times in 6 months. Compare this to perhaps 1000 downloads on average in the first 6 months for the average scientific article.

As before, I have included three separate lists: the “top” articles with the most downloads, the highest Altmetric score, and the most citations. The number of article downloads is a general measure of interest in the topic. The Altmetric score tends to reflect “hot topics,” or newsworthy issues publicized on social media and news outlets. The number of citations to a publication is references from other articles in the scientific literature. Higher numbers in each of these categories is related to higher impact.

The following publications in Radiology had the most downloads in the last 12 months, starting with the most downloaded article:

Congratulations to the authors of these articles. The 10 articles in each category represent only 0.3% of the articles we received—thousands of other authors have worked equally hard at their own topics that attempt to advance medical imaging. We very much appreciate the contributions of all of our authors.
