Publication of material presented at radiologic meetings: authors' country and international collaboration

PURPOSE: To estimate the influence of the authors' country and collaboration on the probability of subsequent full publication of material from oral presentations at the 2000 European Congress of Radiology (ECR). MATERIALS AND METHODS: After searching the Medline database for articles published between 2000 and 2003, all articles that originated from presentations at the ECR in 2000 and were published in journals indexed in the Journal Citation Report were evaluated. Relative likelihood of full publication depending on the country in which an abstract originated was compared with that of Austria, which is the host country of the ECR. The chi(2) test was used to compare publication rates according to country of origin and collaboration. The median and interquartile range of the impact factor of publications according to country of origin and collaboration in the abstract were analyzed by using the Kruskal-Wallis test. The percentage of articles published in journals ranked in the top quartile (top 25% of journals according to impact factor) was calculated. RESULTS: Of 1020 presentations, 403 articles (39%) with significant (P < .001) variations according to country of origin were identified. Studies originating from the United States had the highest percentage of full publication (62%; relative likelihood, 1.41), median impact factor (4.5), and percentage of articles in the top quartile (54%). Radiology was the top quartile journal, with the most articles published (60%). Impact factor differed according to country of origin (P < .001). Abstracts submitted with collaboration between (a) European countries and countries outside of Europe (other than the United States) and (b) different European countries had the highest publication rates (83% and 52%, respectively; P = .03). CONCLUSION: The country of origin of an abstract was useful in predicting the chances of full publication of the abstract, with the United States having the highest publication rate. Authors were more likely to publish an article if it had been prepared with international collaboration.     

Technology and archives in radiology research: a sampling analysis of articles published in the AJR and Radiology. American Journal of Roentgenology.

OBJECTIVE: Our aim was to determine the use of advanced technology and archiving and the contribution of countries other than United States in the articles published in the American Journal of Roentgenology (AJR) and Radiology. We analyzed the association of these features with the type of research, the main technical features of the modalities used, and the countries of origin. MATERIALS AND METHODS: We determined the proportion of articles published in 18 randomly selected issues of the AJR and Radiology that required advanced imaging techniques and relied on the analysis of archived data. "Advanced technology" was defined as imaging techniques that serve a purpose other than simple anatomic imaging or that are not widely available because of the high cost of the technology, such as functional imaging and computer programming designed for an individual study or simulation studies. We analyzed the association of these features with the country of origin, the topic, and the methodology used. RESULTS: Sixteen percent of the studies required advanced technology. MR imaging, CT, and sonography were the most frequently used modalities (31%, 27%, and 15% of studies, respectively). Archiving was used in 37% of the studies, and 67% of the original articles were prospective. The articles most commonly originated in North America (67%), Europe (20%), and Asia (12%). CONCLUSION: Only a small percentage of published research studies required advanced technology and approximately one third of the studies used archiving. These results may suggest that other criteria, such as the design of the study, its relevance for daily clinical use, and the originality of the paper, have a major impact on the acceptance of papers in clinically oriented radiology journals.     

Characteristics and Trends of Radiology Research: A Survey of Original Articles Published in AJR and Radiology between 2001 and 2010

Purpose: To determine the characteristics and trends of the original articles published in two major American radiology journals, AJR American Journal of Roentgenology (AJR) and Radiology, between 2001 and 2010. Materials and Methods: This was a retrospective bibliometric analysis that did not involve human subjects and was exempt from institutional review board approval. All 6542 original articles published in AJR and Radiology between 2001 and 2010 were evaluated. The following information was abstracted from each article: radiologic subspecialty, radiologic technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, affiliation of the first author, and country of the first author. In addition, all the variables examined were presented along with the trend over time. Results: The most common subspecialty of study was abdominal (1219 of 6542, 18.6%), followed by vascular/interventional (804 of 6542, 12.3%). A total of 3744 (57.2%) original articles used magnetic resonance (MR) imaging or computed tomography (CT), 5495 (84.1%) were clinical research articles, 3060 (46.8%) had sample size of more than 50, 4087 (62.5%) were retrospective, 4714 (72.1%) performed statistical analysis, 6225 (95.2%) showed positive study outcome, 4784 (73.1%) were not funded, 3942 (60.3%) had four to seven authors, and 5731 (87.6%) were written by the primary author who was from a department of radiology or radiology-related specialties. The United States published 45.5% (2975 of 6542) of the articles, followed by Japan (n = 525, 8.0%), Germany (n = 485, 7.4%), and South Korea (n = 455, 7.0%). In the time trend analysis, the following variables showed a significantly positive trend: cardiac subspecialty, CT and MR imaging as the radiologic techniques, type of research as other (nonbasic, nonclinical), sample size of more than 50, four to seven as the number of authors, medicine-related department of the first author, and South Korea and Italy as countries of the first author. On the other hand, pediatric subspecialty, combined (basic and clinical) type of research, and number of authors fewer than four showed a significantly negative trend. Conclusion: The bibliometric analysis of the AJR and Radiology journals with articles published between 2001 and 2010 revealed characteristics and trends of the current radiology research that may provide useful information to researchers and editorial staff in radiology. ?

Research articles published in clinical radiology journals: trend of contribution from different countries

RATIONALE AND OBJECTIVES: To determine different countries' trend of contribution to clinical radiology journals and its relationship with impact factor. MATERIALS AND METHODS: All the journals, which publish articles on clinical radiology, were selected from the category of Radiology and Nuclear Medicine group of journals, and articles published in these journals between 1991 and 2000 were searched for the authors' affiliation using the Medline database. Then, share of research output of the top-ranking 20 countries was determined along with the trend over time. Also, the relationship of different countries' contribution with the impact factor of journals was examined by cross-sectional time-series linear model. RESULTS: Of total articles (38,359), the United States' share for the selected journals in clinical radiology was 43.2% (16,582 articles) and ranked top in the world, followed by the United Kingdom (9.9%) and Japan (8.0%). The recent increase in the share was statistically significant for Japan, France, Germany, Italy, South Korea, Turkey, Spain, Switzerland, Austria, and China. On the other hand, the United States, United Kingdom, and Canada showed a significant negative trend. Among the top-ranking 10 countries, the US contribution was significantly higher to journals with high-impact factors, whereas the opposite was true for France. CONCLUSION: The United States, United Kingdom, and Canada showed a negative trend over the last decade in terms of proportion of contribution of articles to the clinical radiology journals. However, only the United States published more articles in high-impact factor journals.     

Terminology and Reporting Criteria for Radiofrequency Ablation of Tumors in the Scientific Literature: Systematic Review of Compliance with Reporting Standards

Objective

To perform a systematic review of compliance with standardized terminology and reporting criteria for radiofrequency (RF) tumor ablation, proposed by the International Working Group on Image-Guided Tumor Ablation in 2003, in the published reports.

Materials and Methods

Literature search in the PubMed database was performed using index keywords, PubMed limit system, and eligibility criteria. The entire content of each article was reviewed to assess the terminology used for procedure terms, imaging findings, therapeutic efficacy, follow-up, and complications. Accuracy of the terminology and the use of alternative terms instead of standard terminology were analyzed. In addition, disparities in accuracy of terminology in articles according to the medical specialty and the type of radiology journal were evaluated.

Results

Among the articles (n = 308) included in this study, the accuracy of the terms ''procedure or session'', ''treatment'', ''index tumor'', ''ablation zone'', ''technical success'', ''primary technique effectiveness rate'', ''secondary technique effectiveness rate'', ''local tumor progression'', ''major complication'', and ''minor complication'' was 97% (298/307), 97% (291/300), 8% (25/307), 65% (103/159), 55% (52/94), 33% (42/129), 94% (17/18), 45% (88/195), 99% (79/80), and 100% (77/77), respectively. The overall accuracy of each term showed a tendency to improve over the years. The most commonly used alternative terms for ''technical success'' and ''local tumor progression'' were ''complete ablation'' and ''local (tumor) recurrence'', respectively. The accuracy of terminology in articles published in radiology journals was significantly greater than that of terminology in articles published in non-radiology journals, especially in Radiology and The Journal of Vascular and Interventional Radiology.

Conclusion

The proposal for standardization of terminology and reporting criteria for RF tumor ablation has been gaining support according to the recently published scientific reports, especially in the field of radiology. However, more work is still needed for the complete standardization of terminology.     

Scientific papers presented at the European Congress of Radiology 2000: publication rates and characteristics during the period 2000–2004

To determine the rate at which abstracts orally presented at the ECR 2000 were published between 2000–2004, and to identify predictive factors of publication and differences between abstracts and subsequently published papers. Specific search profiles were devised to retrieve items from the Medline database. From 1020 abstracts originating from 39 countries, 479 articles (publication rate 47%) were subsequently published in 139 Medline-indexed journals, most frequently in European Radiology (14%). Country of origin statistically (P<0.0001) influences the subsequent publication of the abstract, Germany having the highest number of presentations (n=343) and derived articles (publication rate 54%). Abstracts presented by authors from the USA (n=21) had the highest publication rate (76%). Most papers were published within the first 3 years after the meeting, as original articles and in English-language journals. Both the study sample size and the first author frequently changed. Chest and cardiac studies had the highest publication rates (56%, both). In summary, abstracts presented at the ECR 2000 had a high publication rate in Medline-indexed journals. Country of origin and subspecialty of presentation appeared to influence subsequent full publication. More articles were published in European Radiology than in other journal.     

Which vendor is most cited in the hepatic imaging literature?

PurposeWhen deciding among imaging equipment vendors, one may use a vendor's prevalence in peer-reviewed publications as a measure of their research and development. We sought to determine which vendors, countries, and journals were dominant in hepatic imaging literature of 2018 with respect to magnetic resonance (MR), computed tomography (CT), and ultrasound (US).MethodsWe recorded and analyzed the modality (MR, CT, US), journal, vendor, and authors' country for all original hepatic imaging articles published in 2018 in 29 imaging journals.ResultsOf 197 MR articles, investigators used Siemens in 98 (50%), General Electric (GE) in 65 (33%), and Philips in 63 (32%). Of 115 CT articles, investigators mentioned Siemens in 55 (48%), GE in 45 (39%), Philips in 25 (22%) and other vendors in 27 (24%). Of 68 ultrasound articles, Siemens dominated with 27 (40%), versus GE with 19 (28%), Philips with 11 (16%), and other vendors with 42 (62%). We found a significant difference in vendor usage for MR, CT, and all modalities (p < .01). The plurality of articles was written in the United States (73 [23%]) with South Korea (56 [17%]) and China (56 [17%]) following. European Radiology published the most hepatic articles. For American journals, we found a significant difference in MR (p = .02) and CT (p < .01) vendor usage, whereas non-American journals nearly reached significance in MR (p = .06) and CT (p = .06) vendor usage.ConclusionSiemens was the most cited vendor in hepatic imaging literature for all modalities. American institutions and non-American journals published the most hepatic imaging articles.     

A review of contrast media research in 1999-2000

Contrast media research published during the years 1999 and 2000 is reviewed in this article, in terms of relevance to developments within the field of diagnostic radiology. The primary focus is on publications from the journal Investigative Radiology, which publishes much of the clinical and laboratory research performed in this field. The journals Radiology and the American Journal of Roentgenology are dominant in the field of diagnostic radiology and together publish more than 10 times the number of articles as appear each year in Investigative Radiology. However, in 1999 for example, these two journals together published fewer articles than did Investigative Radiology alone that concerned basic (animal) research with contrast media. Thirty-six percent of the articles in Investigative Radiology in 1999 had a primary focus on contrast media and 18% on basic (animal) research with contrast media. To make this review more complete, articles from other major journals are cited and discussed, as needed, to provide supplemental information in the few areas not well covered by articles in Investigative Radiology. The safety of contrast media is always an important topic and research continues to be performed in this area, both to explore fundamental issues regarding iodinated contrast media and also to establish the overall safety profile of new magnetic resonance (MR) and ultrasound agents. In regard to preclinical investigations, most of the work performed in the last 2 years has been with MR and ultrasound. In MR, research efforts continue to be focused on the development of targeted agents. In ultrasound, research efforts are split between studies looking at new imaging methods and early studies of targeted agents. In regard to the clinical application of contrast media, the published literature continues to be dominated by MR. Investigations include the study of disease in clinical trials and in animal models. A large number of studies continue to be published in regard to new techniques and applications within the field of contrast-enhanced magnetic resonance angiography. This field represents the single, largest new clinical application of contrast media in MR to emerge in the last decade. New clinical research continues to be published regarding the use of contrast media in computed tomography (CT), ultrasound, and x-ray angiography. The introduction of spiral CT (together with the multidetector scanners) has led to greater utilization of this modality, as well as intravenous iodinated contrast media. The number of publications regarding clinical applications of intravenously injected ultrasound contrast agents remains low, with the high expectations in regard to growth (in terms of number of exams using contrast) of the last decade yet to be fulfilled.
