The Access to Radiology Information (ARI) integration profile is part of the IHE Radiology Technical Framework.

This profile specifies a number of query transactions providing access to radiology information, including images and related reports, in a DICOM format as they were acquired or created. Such access is useful both to the radiology department and to other departments such as pathology, surgery and oncology.
