A Web-based ACR index for radiological diagnoses.

Objective: We created an online computer system that allows radiologists to access the American College of Radiology (ACR) index for radiologic diagnoses from any Web browser.

Conclusion: A total of 11,260 indexes (10 anatomic, 722 pathologic, 90 subanatomic, and 10,438 subpathologic) were integrated into this online system. Users can navigate the entire ACR hierarchic indexing structure with easy-to-use cascading dropdown lists. This password-protected system also allows free-text searches, ACR index searches, and bookmark functions. We have used this system in our departmental intranet for more than 2 years.
