Radiology Information System (RIS)

Radiology Information System (RIS) is a system that manages the workflow of the radiology department — request management, scheduling, worklist, reporting, and result distribution. It works in conjunction with PACS to form the backbone of the radiology process.

While RIS manages the administrative and reporting flow from the receipt of the request to the approval and sharing of the report, the storage and viewing of images are provided by PACS.

Other names / abbreviation: Radiology Information System.

What is its purpose?

RIS standardizes the radiology workflow, shortens reporting times, increases efficiency through worklist management, and ensures timely delivery of reports to the relevant clinicians.

Key features

• Request and worklist: Management of radiology requests and modality worklist.
• Reporting: Structured report templates and approval flow.
• PACS integration: Association of reports with images.
• Result distribution: Delivery of approved reports to clinicians.

• HBYS
• Imaging devices (modalities)

Frequently referenced standards and regulations:

• DICOM
• HL7
• KVKK

Benefits provided
