Picture archiving and communications systems (PACS) and DI repositories (DI-rs) are secure computer systems that contain patient radiology reports and images such as hospital-based CT scans, ultrasounds, MRIs, mammograms and x-rays. The implementation of these systems has eliminated the need for film and paper diagnostic images.DI gives health care providers important information to make better decisions about a patient’s treatment. Authorized health care providers can share images and reports securely with other providers within their respective DI-rs. The diagnostic images and corresponding reports are stored in a regional repository from which they can be retrieved in digital format. This capability is reducing the need for patients to travel to see a specialist.

Support of diagnostic imaging initiatives is part of the agency’s overall strategy to improve patient care, safety and access. By putting in place a stable technical infrastructure, it guarantees that health care providers have access to vital clinical activity information systems when and where they need it. eHealth Ontario coordinates the four DI-r projects covering all hospitals in Ontario and provides funding support and the ONE® Network that gives providers access to the system.
