Contrast agents for medical imaging techniques are described. The contrast agent has particles composed of at least a core, and the core has at least an oxide, a mixed oxide or a hydroxide of a specific element. The particles optionally have a shell comprising (or consisting of) noble metals, radioisotopes, biocompatible agents and / or antibodies. The imaging techniques applied are in particular magnetic resonance tomography (MRI), magnetic particle imaging, positron emission tomography (PET), single photon emission computer tomography (SPECT), computer tomography (CT) And ultrasonic methods (US). |
