We operated a contrast-enhanced computed tomography (CT) system for about one year that stored the conditions for injection of contrast media and patient attributes in the Picture Archiving and Communication System (PACS) and the Radiology Information System (RIS) in the form of DICOM images and text information. The system allowed us to effectively use information on the previous injection of contrast media and made it easy to perform examinations under the same conditions. However, the previous system kept track of injection conditions but did not address information on adverse reactions to contrast media. We developed a new system in which information on adverse reactions to contrast media is managed by the RIS and the automatic contrast medium injector.

Devices used were a Dual Shot GX (Nemoto Kyorindo Co., Ltd.), DBOX EC (Resource One Inc.), and RIS (Yokogawa Electric Corporation). When adverse reactions to contrast media develop, the name of the contrast media used and information on adverse reactions are registered in the RIS. Adverse reactions are graded on a three-point scale according to the classification of severity of the adverse drug reaction, and symptoms are documented on the basis of a pre-specified symptom master. Similarly for late-onset adverse reactions, the name of the contrast media and the date of onset of adverse reactions are registered in the RIS. When patients with information previously registered by the method undergo contrast studies, information on adverse reactions is sent from the RIS to DBOX, and the history of adverse reactions, name of contrast media, and severity of the reaction are displayed on the control panel of the automatic contrast medium injector.

The use of this system facilitated management of the history of adverse reactions to contrast media. The system enhanced safety by displaying an alert for previous adverse reactions on the control panel of the automatic injector along with the name of the contrast media causing the adverse reactions and the severity.

Although there are other systems that manage adverse reactions in the RIS, our system allows even greater safety and more efficient contrast-enhanced CT by sharing information between the RIS and the automatic injector.

The system provides safe and efficient contrast-enhanced CT.
