Resovist® is an organ-specific MRI contrast agent, used for the detection and characterization of especially small focal liver lesions.
Resovist® consists of superparamagnetic iron oxide (SPIO) nanoparticles coated with carboxydextran, which are accumulated by phagocytosis in cells of the reticuloendothelial system (RES) of the liver. The uptake of Resovist® Injection in the reticuloendothelial cells results in a decrease of the signal intensity of normal liver parenchyma on both T2- and T1 weighted images.
Most malignant liver tumors do not contain RES cells and therefore do not uptake the iron particles. The resulting imaging effect is an improved contrast between the tumor (bright) and the surrounding tissue (dark).
Resovist® is injected as an intravenous bolus, allows immediate imaging of the liver, and therefore reduces the overall examination time. A dynamic imaging strategy after bolus injection allow to characterize lesions. In comprehensive clinical trials, it demonstrated an excellent safety profile.
In 2001, Resovist® was approved for the European market.

Short name: SHU 555 A, generic name: Ferucarbotran
A RES-directed MRI contrast agent (SPIO) made-up of a colloidal sol of iron oxide nanoparticles coated with carboxydextran (Resovist®, Cliavist™).
It is used for the detection and characterization of especially small focal liver lesions and offers the opportunity to make a reliable diagnosis at a very early stage of patients with suspected liver tumors.
Bayer Schering Pharma AG announced that it has received marketing approval for the liver-specific contrast agent Resovist® in Japan. See Contrast Agents and Superparamagnetic Contrast Agents.
