Interactive, Computer-Based Pediatric Chest Atlas

Objectives: The authors created a computer-based, interactive atlas of pediatric chest radiographs to facilitate (1) understanding of normal variants and (2) interpretation of pediatric chest radiographs in the acute setting. Methods: Seventy-three normal pediatric chest radiographs were selected for inclusion in the atlas by consensus after review by 3 pediatric radiologists. Sixteen abnormal pediatric chest radiographs showing a variety of abnormalities (infection, malignancy, congenital abnormalities, foreign body, and acquired disease), as well as 4 normal adult chest radiographs, were also included in the atlas. Images for the atlas were derived from Digital Imaging and Communications in Medicine-compliant data. The atlas software was written in C# and offers features of a picture archiving and communication system viewer. In addition, the atlas offers annotated series that describe particular radiographic features of normal variants and disease. Results: The digital, interactive pediatric chest atlas displays normal chest radiographs of children aged 7 days to 17.8 years, as well as 4 normal adult chest radiographs and 16 abnormal pediatric chest radiographs. The digital interactive format of the atlas allows for (1) easy manipulation of atlas cases and (2) direct comparison between normal atlas cases and provided abnormal cases, as well as (3) the potential for direct comparison with images displayed on an institution's picture archiving and communication system. The atlas is available for free download at http://www.seattlechildrens.org/radiologyeducation/pediatric-chest. Conclusions: Improved interpretation of pediatric chest radiographs in the acute setting may be facilitated by a comprehensive, computer-based, pediatric chest atlas.
