CT examination imaging methods have been very dynamic recently due to performance improvements in CT scanners and injector systems. The contrast media injection method is important diagnostic data when referencing images. Specifically, the contrast media injection volume and flow rate are critical data in terms of patient’s examination data. The purpose of this paper is to review an examination data control system that was developed and implemented into our practice.

The system consisted of a radiology information system (RIS) manufactured by Yokogawa Electric Corporation, a Dual Shot GX injector system, manufactured by Nemoto Kyorindo Co. Ltd., a contrast enhancement evidence creator (EC), manufactured by Resource One Co. Ltd., and a PACS system. Patient data (including the examination area) is transmitted to the Modality Worklist Management (MWM) server from the RIS. The injector acquires the patient data through the EC which is connected to the MWM. The user interface on the injector will display the patient name, patient ID, weight, etc. The injection flow rate and volume that was set in the injector are also displayed. The injector syringe was equipped with an IC tag that automatically provides the contrast medium name, lot number and iodine amount to the injector. Upon completion of the examination, the RIS will request and save from the EC the injection volume, flow rate, injection time and maximum injection pressure. Additionally, an image of the injector’s console display is transmitted via DICOM to the PACS to be saved as part of the CT examination images. Direct viewing of the injection data and the CT examination is then possible on an imaging viewer.

A CT imaging examination data control system was able to be developed and implemented into practice.

Reproducible imaging examinations have become possible and practical by mitigating the risk of errors during data entry and by eliminating the time and effort required for data entry.

By using a CT imaging examination data control system, it is possible to save injection protocol data of each examination as images into a PACS and as text data into a radiology information system.
