Diagnostic Imaging Common Service Standard (DI CS)

This initiative will enhance the delivery of patient care in Ontario by building on the success of regional diagnostic imaging repositories. It will provide comprehensive secure access to a patient’s provincial longitudinal digital imaging record from anywhere and at any time, as well as consistent displays of information to clinicians at point-of-service. The digital imaging common service standard will be used by system implementers to support the sharing of digital imaging reports and images.

Key benefits include: consistent data exchange format across the regional diagnostic imaging repositories, easier access for retrieval of reports and images for viewing, and standardized naming of diagnostic procedures for consistent naming across the province.


The diagnostic imaging common service initiative enables and supports sharing and viewing of diagnostic imaging results across Ontario to all hospital and community-based health care providers anytime, anywhere, using the tools best suited to their work practices. Currently it offers clinicians the ability to view reports through eHealth Ontario’s ONE® Portal. This will be followed by both of the provincial diagnostic imaging viewers, electronic medical record devices and individual organizations’ picture archiving and communications systems.
