Finding the Path: a World Wide Web-based guide for imaging evaluation of patients in the emergency department.

Author information

Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.


Finding the Path is a problem-based World Wide Web resource that provides algorithms for imaging evaluation of emergency department patients. This module is designed to guide physicians in the efficient use of diagnostic imaging modalities and their appropriate application to emergency department practice. The module is composed of interactive case studies that can be accessed either by diagnoses or as unknowns. Each case study provides a brief clinical history accompanied by pertinent physical and laboratory findings. Users are asked to choose the most appropriate and cost-effective diagnostic imaging study and receive feedback on their choice. Associated images, findings, and a brief discussion of the diagnosis are displayed. Each case is followed by an algorithm aimed at promoting efficient and cost-effective use of imaging modalities. In addition to its value in clinical practice, the database is a useful radiologic teaching tool for residents and medical students. The module is being used at a major university as part of the new curriculum for radiologic education.
