The most-cited articles in pediatric imaging: a bibliometric analysis.

INTRODUCTION: The number of citations that an article has received reflects its impact on the scientific community. The purpose of our study was to identify and characterize the 51 most-cited articles in pediatric imaging. EVIDENCE ACQUISITION: Based on the database of Journal Citation Reports, we selected 350 journals that were considered as potential outlets for pediatric imaging articles. The Web of Science search tools were used to identify the most-cited articles relevant to pediatric imaging within the selected journals. EVIDENCE SYNTHESIS: The 51 most-cited articles in pediatric imaging were published between 1952 and 2011, with 1980-1989 and 2000-2009 producing 15 articles, each. The number of citations ranged from 576-124 and the number of annual citations ranged from 49.05-2.56. The majority of articles were published in pediatric and related journals (N.=26), originated in the USA (N.=23), were original articles (N.=45), used MRI as imaging modality (N.=27), and were concerned with the subspecialty of brain (N.=34). University College London School of Medicine (N.=6) and School of Medicine University of California (N.=4) were the leading institutions and Reynolds EO (N.=7) was the most voluminous author. CONCLUSIONS: Our study presents a detailed list and an analysis of the most-cited articles in the field of pediatric imaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

The one-hundred most-cited articles focused on thyroid research: a bibliometric analysis.

INTRODUCTION: The number of citations that an article has received reflects its impact on a particular research area. EVIDENCE ACQUISITION: We determined the one-hundred most-cited articles in thyroid research via the Institute for Scientific Information Web of Knowledge database, using the search term. The following parameters were used to analyze the characteristics of the 100 most-cited articles: publication year, journal (including subject category and impact factor), number of citations and annual citations, authors, department, institution, country, type of study, and topic. EVIDENCE SYNTHESIS: The number of citations for the 100 most-cited articles ranged from 2521 to 412 (mean, 643.4) and the number of annual citations ranged from 392.9 to 7.1 (mean, 38.0). The majority of articles were published in 2000-2009 (32%), published in endocrinology journals (29%), originated in the USA (70%), were clinical observation study (31%), and dealt with nodular thyroid disease (32%). Department of Internal Medicine, Johns Hopkins University School of Medicine and Department of Internal Medicine, Ohio State University College of Medicine (N.=6 each) were the leading institutions and Mazzaferri EL (N.=7) was the most prolific author. CONCLUSIONS: Our study presents a detailed list and analysis of the 100 most-cited thyroid research articles, which provides a unique insight into the historical development in this field.
