## Abstract

The arrival of high speed digital electronic and communication technologies
in radiological sciences is gradually changing the method of acquiring,
communicating, storing, retrieving, viewing, and manipulating diagnostic
images.  One natural development from this change is the emergence of the
digital radiology department.  Five major issues in a digital-based
operation radiology department are technological feasibility, diagnostic
image quality, clinical implementation, clinical assessment, and system
utilization and research applications.  During the past six years with the
support from the existing grant, we have solved the first two issues
related to pediatric radiology.  We are now ready to move on to the other
PACS issues of clinical implementation, assessment and research
applications.

The specific aim of this research proposal is to continue developing the
digital-based operation in pediatric radiology.  Two hypotheses are
investigated:  (1) The digital-based operation to be implemented can
effectively replace the current film-based operation for all tasks
necessary for routine clinical operation.  The framework developed in this
study will allow new clinical machines and information management systems
to be easily incorporated into the larger departmental schema.  (2) The
digital-based operation provides the framework to effectively perform
education and research activities.  The digital-based operation developed
in this study will allow new image and database analysis modules to be
easily connected to a large repository of information stored in the
departmental picture archiving and communication system (PACS).

The first hypothesis will be tested by first completing the implementation
of a digital-based operation in pediatric radiology, then performing
statistical tests to assess whether performance differences exist between
the two alternative systems (film -vs- digital).  The second hypothesis
tests the ability for the digital-based operation to facilitate education
and research.  Two tasks, one on developing a pediatric MR interactive
teaching module and the other on a pediatric skeletal model, will be
performed to test the hypothesis.

If we are successful, the practice, teaching, and research of Pediatric
Radiology will change potentially not only in the United States but
internationally.  Development of a digital-based Pediatric Radiology
Section will allow much more effective patient care and radiology
consultation as well as better methods of teaching and research in
Pediatric Radiology.  Development of a scientific database will allow a
better understanding of the normal and the pathological status of
childrens' disease processes.
