A method of displaying stored injection parameters in a contrast media injector system, the method comprising: displaying on a connected display screen (30, 32) of said injector system, a plurality of stored injection protocol identifiers, wherein each said identifier enables a user to retrieve a corresponding stored injection protocol, and wherein each stored injection protocol comprises a plurality of stored injection parameters that are also displayed on said display screen along with their corresponding stored injection protocol identifiers; displaying on said display screen a selected group identification corresponding to a particular set of stored injection protocol identifiers and corresponding stored injection parameters, wherein said particular set comprises said plurality of stored injection protocol identifiers and said plurality of stored injection parameters, and wherein each member of said particular set is displayed on said display screen while said selected group identification is displayed; displaying on said display screen additional, non-selected group identifications corresponding to other sets of stored injection protocol identifiers and corresponding stored injection parameters, wherein said other sets each comprise other stored injection protocol identifiers and corresponding stored injection parameters, wherein said other stored injection protocol identifiers and corresponding stored injection parameters associated with said other sets are not displayed on said display screen during the displaying of each member of said particular set associated with said selected group identification, and wherein said displaying steps are performed simultaneously. displaying on a connected display screen (30, 32) of said injector system, a plurality of stored injection protocol identifiers, wherein each said identifier enables a user to retrieve a corresponding stored injection protocol, and wherein each stored injection protocol comprises a plurality of stored injection parameters that are also displayed on said display screen along with their corresponding stored injection protocol identifiers; displaying on said display screen a selected group identification corresponding to a particular set of stored injection protocol identifiers and corresponding stored injection parameters, wherein said particular set comprises said plurality of stored injection protocol identifiers and said plurality of stored injection parameters, and wherein each member of said particular set is displayed on said display screen while said selected group identification is displayed; displaying on said display screen additional, non-selected group identifications corresponding to other sets of stored injection protocol identifiers and corresponding stored injection parameters, wherein said other sets each comprise other stored injection protocol identifiers and corresponding stored injection parameters, wherein said other stored injection protocol identifiers and corresponding stored injection parameters associated with said other sets are not displayed on said display screen during the displaying of each member of said particular set associated with said selected group identification, and wherein said displaying steps are performed simultaneously.
