A scalable and flexible SOA based contrast management system with role-based acccess has the potential of being a valueable tool for optimizing CT procedural workflow.

The reporting of contrast usage in radiology is important for ensuring compliance with regulatory and quality standards, for tracking clinical effectiveness, and for optimizing practice management. A few proprietary, custom solutions exist. We have developed a scalable, open-architecture approach that enables the capture of injection information for retrospective review by technologists, radiologists, and site adiministrators.This platform can be scaled and extended to enable interoperability with other actors in the imaging enterprise such as the RIS, PACS and imaging modalities. Several simulated and conceptual models of the proposed integrated workflow are presented.

We demonstrate the utility of our platform in a few clinical use environments.The injection logging systems were deployed in academic radiology departments. The recorded data demonstrate the distribution of injection pressures, achievable flow rates and trends in contrast usage. One clinically useful finding is the hydraulic pressure curve measured by the injector during a pressure-limit situation. We also present  examples of unexpected pressure behaviors measured by the system. The protoype scanner-injector integration workflow model presents an opportunity to reduce operator error, ensure consistent inejctor and scanner timing syncronization.

The preliminary operational results demonstrate the wide utility of the collected data for better understanding and managing contrast and its delivery. Example trends include the correlation between injection pressures, programmed flow rates and contrast physiochemical properties. Future oppourtunities that enable the inregration of the injection information system into the RIS afford unique workflow and medication management improvements.
