Information systems in the management of the radiology department.

Clinical, organizational and administrative service improvement has always been the primary aim of a radiology information system. Studies carried out at Massachusets General Hospital in the late sixties identified two "bottlenecks" in the Departments of Diagnostic Imaging: the planning of examinations and the management of picture archiving. Therefore, the information system started to be viewed as a potential tool for the solution of these problems. In time, the concept of Radiology Information System (RIS) was conceived. With its developments it is now considered an effective support for the daily activity of the Radiology department, to tackle and solve the operational problems posed by the various healthcare professionals. A radiology information system essentially concerns three functional areas: the patient management, the procedure management, the department management. Another major task of RIS is represented by its integration with the other information systems of Radiology and hospital to enable to share information in real time with the hospital information system (HIS) and the other information systems (system of first-aid management, intensive therapy units etc). A modern RIS must be in conformance with DICOM 3 for the service class of the working list to be able to transmit to the diagnostic imaging equipment the patient correct names and demographics and the type of procedure to be performed.
