A computer-implemented method for peer exchange of data between injection systems comprising: storing, with at least one first injection system, a plurality of injection control data sets; determining, with the at least one first injection system, a first subset of the plurality of injection control data sets according to which the at least one first injection system is configured to control delivery of at least one fluid to a patient; providing, at the at least one first injection system, the first subset of the plurality of injection control data sets for selection of an injection control data set for use in delivering the at least one fluid to the patient with the at least one first injection system; transmitting, with the at least one first injection system, the plurality of injection control data sets to at least one second injection system; storing, with the at least one first injection system, a plurality of identifiers associated with a plurality of injection systems including the at least one first injection system, the at least one second injection system, and at least one third injection system; modifying, with the at least one first injection system, one or more injection control data sets of the plurality of injection control data sets, wherein at least one identifier of the at least one third injection system identifies the one or more injection control data sets according to which the at least one third injection system is configured to control delivery of the at least one fluid to the patient; and transmitting, with the at least one first injection system, the plurality of identifiers and the plurality of injection control data sets to the at least one second injection system. storing, with at least one first injection system, a plurality of injection control data sets; determining, with the at least one first injection system, a first subset of the plurality of injection control data sets according to which the at least one first injection system is configured to control delivery of at least one fluid to a patient; providing, at the at least one first injection system, the first subset of the plurality of injection control data sets for selection of an injection control data set for use in delivering the at least one fluid to the patient with the at least one first injection system; transmitting, with the at least one first injection system, the plurality of injection control data sets to at least one second injection system; storing, with the at least one first injection system, a plurality of identifiers associated with a plurality of injection systems including the at least one first injection system, the at least one second injection system, and at least one third injection system; modifying, with the at least one first injection system, one or more injection control data sets of the plurality of injection control data sets, wherein at least one identifier of the at least one third injection system identifies the one or more injection control data sets according to which the at least one third injection system is configured to control delivery of the at least one fluid to the patient; and transmitting, with the at least one first injection system, the plurality of identifiers and the plurality of injection control data sets to the at least one second injection system. <EOS>
