100 classic papers of interventional radiology: A citation analysis

AIM: To define the 100 citation classic papers of interventional radiology.METHODS: Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed.RESULTS: The top paper received 2497 citations and the 100 th paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953- 2005. Most papers originated in the United States(n = 67) followed by Italy(n = 20) and France(n = 10). Harvard University(n = 18) and Osped Civile(n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with "Radiology" and "AJR" making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers(n = 61) were published after 1990.CONCLUSION: This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty.

Outcomes research and cost-effectiveness analysis in radiology

The decision to implement a new medical technology requires that if not only increases survival or quality of life, but that it is also economically sound. The unique feature in the assessment of diagnostic tests is that the results of such tests are intermediate outcomes. Both randomized controlled clinical trials and decision analysis have an important role to play in the assessment of diagnostic tests. Important points to consider when performing a cost-effectiveness study are what perspective to take; comparing the technology with the next best strategy; including both effectiveness and costs; the distinction between describing and valuing the quality of life; intangibles such as the value of information; and the incremental cost-effectiveness ratio.

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.

Measuring interdisciplinarity of biomedical research,medical specialty performance,and implications for radiology: A retrospective review of 2.6 million citations

PurposeTo assess and determine the overall interdisciplinarity and impact of radiology and imaging sciences research.MethodsUtilizing the Thomson Reuters Web of Science, the top 15 journals rank-ordered by impact factor in each of 10 major medical subspecialties were identified. The 2012 impact factors for these journals were noted. All articles published in these journals between 2012 and 2014 were then used to produce an index list of publications. We next generated a list of all published articles in the ensuing 5-year period that cited any publication present on our index list. These data were then used to calculate an interdisciplinarity score (DIV*) for 146 unique scientific journals. The correlation between the impact factor and the DIV* score was calculated with Kendall's τ.ResultsThe quantitative measure of research interdisciplinarity, DIV*, is significantly correlated with journal impact factor (τ = 0.201, p < 0.001). Research journals within radiology, nuclear medicine, and medical imaging ranked 5th among 10 clinical subspecialties by mean impact factor but ranked second-to-last in mean DIV*.ConclusionThe interdisciplinarity score DIV* is positively correlated with journal impact factor, demonstrating the greater impact and reach of interdisciplinary research. Further, we found radiology, nuclear medicine, and medical imaging research to have one of the lowest measures of DIV* among the 10 major clinical subspecialties. Our findings suggest and point to new opportunities and directions that can expand the breadth and impact of radiology research as well as new ways to increase our reach and audience in the clinical scientific literature.

两所高等医学院校临床本科生介入放射学认知度调查

目的 探讨介入放射学课程对临床医学本科生介入放射学认知度的影响.方法 采用问卷式调查方式对两所高等医学院校分别独立修学(教学组)和未修学(对照组)介入放射学课程临床医学专业本科实习生介入放射学知识进行匿名调查,主要调查内容为介入放射学知识掌握情况、介入放射学职业前景评判等.采用频数分析和x2检验对两组调查数据结果进行比较.结果 对照组75％学生(71/95)对介入放射学知识了解“少”或“无”,教学组28％学生(28/100)对介入放射学知识了解“少”或“无”,教学组学生对介入放射学知识了解程度明显高于对照组(P＜0.05).两组共有87％学生认为介入放射学有较好就业前景,但仅有13％学生考虑将其作为终身职业(对照组20％,19/95;教学组6％,6/100).部分学生因不了解介入放射学知识而不愿意将其作为终身职业(对照组85％,65/76;教学组23％,22/94).结论 临床医学本科生系统学习介入放射学理论知识,有助于提高介入放射学认知度.

DataServer: an infrastructure to support evidence-based radiology

Following a requirements analysis for development of an information infrastructure supporting evidence-based radiology, the objective of this study was the development of a data gateway to support flexible access to the totality of a patient's electronic medical records through a single, uniform representation, regardless of the underlying data sources (eg, hospital information systems [HIS], radiology information systems [RIS], picture archiving and communication systems [PACS]). XML-based (eXtensible Markup Language) technologies were employed to create an application framework permitting querying of different clinical databases. The contents of different data sources were represented by using XML. On the basis of these representations, users can specify queries. The system transforms the XML queries into a query format understood by the specific databases, processes the query, and transforms the results back into an XML format. XML results can then be transformed in accordance to different data-formatting standards. Access to several different data sources, including HIS, RIS, and PACS, has been accomplished with this framework. The extensible nature of the XML data gateway enables data sources to be readily added. The framework also provides a means by which data can be systematically de-identified to protect patient confidentiality, thus supporting research endeavors.
