MRI guidance of interventions is a goal. Current embolization particles cannot be detected by an imaging modality (clinical) or only by CT/X-ray (research). Here, we developed and tested the first multimodal embolization particles being visible within MRI and CT/x-ray. An animal model was used. Post embolization imaging confirmed dual-modality contrast as embolized areas could be detected by CT and MRI. Histology confirmed results. The particles consist of two clinically approved substances: polymerized Iodine and USPIO. Once introduced into clinical routine, improvements of embolization therapy can be expected, because both CT and MRI could be used for treatment control.
