The workflow (a&b) start when a clinician enters anorder for an imaging exam into the EMR . In the past the order would have been sent directly into a Radiology Information System and scheduled. In the new workflow the EMR first sends the order to another module or system, The Radiology CDS. Here the order is evaluated to determine if it is appropriate, using a reference source such as the ACR-AC. If the evaluation results in a high score the order is sent directly to the RIS. If the order is receives an intermediate or low score a message is returned to the EMR (c* or d*) indicating that this might not be the best choice. Alternative examinations may be suggested and in some systems references may be provided. Figures c & d simply show different styles of returning this information. The clinician may continue with the original order or choose one of the suggestions.
