Abstract:

HTML

A digital index of reference hand images was developed on hand-held PDA devices and on standard personal computers as an alternative to traditional reference textbooks and atlases, such as the Greulich and Pyle. Due to the large variability in maturation of ossification in the normal population, we elected to generate a set of ideal images obtained by computer combinations of images from our normal reference data sets for each age category. The system allows navigation through images and selects the closest image to a given patient study. A formula based on patients chronological age provides the standard deviation from normal. The accuracy of the program compared favorably to traditional interpretation methods in a clinical trial conducted on 200 normal children. The system brings the convenience and effectiveness of portable digital reference to clinical practice and can be easily expandable to different sets of reference image data for various ethnic groups.

 


Learning Objectives:
1. Demonstrate an electronic PDA-based alternative to reference books and atlas for the assessment of bone maturity 2. Educate the users on a more efficient technique of interpretation of bone age images 3. Illustrate the value of computer generated image combinations of idealized reference images for visual comparative interpretation of image data
