A radiology information system is a software suite that has been networked to manage medical imagination and associated data. It is useful for managing radio-logic records and related data in multiple locations. It is used in conjunction with a (PACS) I. E., picture archiving and communication system in order to manage work flow and billing. It was first used around 1970s with a primary aim of managing and storing relevant data for a patient. The introduction of server/client computing has ameliorated digital imagination, and electronic network technologies, in line with the progress of the DICOM and HL7 measures have put RIS and (PACS) as a viable solution for administering radiological images. After 1990s, firms had taken steps to fully incorporate PACS with radioscopy data scheme, when the basic characteristics and adaptation needed to handle the acquisition, and storage of radiological data, becomes the obligation of the RIS. The key areas that are addressed by this scheme include the following. Patient Management: they are used to administer the entire work flow of a patient within the radioscopy department, pictures and reports can be retrieved from and added to an electronic medical records and viewed by the relevant staff. It also helps in Scheduling: Patient assignments for outpatients and inpatients can be scheduled on receipt of an order. Functions for programming; the available radiology staff and time slots allocation. Patient tracking: it offers the ability to track patient from the instant he or she is admitted to the moment he or she is discharged, with all the radioscopy processes carried out on the patient recorded. This include the past, present and future appointments of the patient. Results reporting: this majorly concerns the outcomes of a group of patients, an individual patient or a process that can be yielded using a radiology information system .
