Purpose or Case Report: To determine the characteristics and trends of original research articles published in Pediatric Radiology over the last 10 years.
Methods & Materials: This was a retrospective bibliometric analysis not involving human subjects.
All original research articles published in the July issues of the Pediatric Radiology journal between 2006 and 2015 were evaluated. Case reports, editorials and pictorial reviews were excluded from analysis.

Information regarding sample size, study design, declared funding, number of authors, author country and gender were examined and analysed for trend over time using the Pearson correlation test. Descriptive statistics were used to illustrate total numbers of articles analysing a particular subspecialty area, radiology modality and study design.
Results: In total 80 articles were analysed, with 10 (13%) articles analysing data from multicentre sources, 40 (50%) with multicentre investigators, 22 (28%) prospective in study design and 9 (11%) with declared funding. The most common pediatric subspecialty topics included gastrointestinal (18, 23%), musculoskeletal (16, 20%) and neuroradiology (11, 14%). Studies assessing a combination of various modalities were most common (23, 29%), along with those utilising CT (19, 24%) and MRI (16, 20%).

There was a significantly positive trend towards number of original research articles being published (r = 0.72, p = 0.02), first authors originating from United States (r = 0.69, p = 0.03) and a negative trend towards total number of authors (r = -0.65, p = 0.04).

There was a positive but not statistically significant trend towards last authors originating from United States (r = 0.48, p = 0.16), studies relating to interventional radiology (r = 0.40, p = 0.25) and the use of statistical analysis tests (r = 0.46, p = 0.18). A negative but not significant trend was seen for the female gender of last authors (r = -0.42, p = 0.23).

There was no trend in study sample sizes, prospective study design, those involving multicentre investigators, using multicentre data, those with declared funding or female gender of first author.
Conclusions: Characteristics of Pediatric Radiology journal research articles over time have been described. This information may be helpful in recognizing current limitations or pitfalls of our published research work and in steering the future directions of research in our specialty, informing prospective researchers and editorial staff.
