A radiology information system (RIS) is a data management system commonly used to support both the clinical and administrative portions of an imaging facility or radiology department. It's typically much smaller in scope than a hospital information system (HIS), though the RIS may very well integrate with the HIS. However, like the HIS, the radiology information system is designed to maintain patient demographics, including referrals, scheduling, examination results, and reporting.[1][2]

The RIS is also designed to be interoperable with picture archiving and communication systems (PACS), HIS, and in some cases even an electronic medical record (EMR). This interoperability is vital in a hospital environment especially, increasing the timeliness of patient workflow and report turnaround to the ordering physician.[1][2]


The typical RIS has the following functionality[1][3]:

  • process patient records, including demographics and check-ins
  • process patient image folders
  • monitor department resources, including examination and work schedules
  • create and distribute digitally signed diagnostic reports
  • maintain billing and insurance information
  • perform limited amounts of data analysis
  • maintain catalogs of radiological procedure and diagnoses codes
  • manage medical devices
