Abstract: There is provided signal modifying compositions for medical imaging comprising a carrier and signal modifying agents specific for two or more imaging modalities. The compositions are characterized by retention efficiency, with respect of the signal modifying agents that enables prolonged contrast imaging without significant depletion of the signal modifying agent from the carrier. The carriers of the present invention are lipid based or polymer based the physico-chemical properties of which can be modified to entrap or chelate different signal modifying agents and mixtures thereof and to target specific organs or tumors or tissues within a mammal.
