Toxicity, biodistribution, and ex vivo MRI detection of intravenously injected cationized ferritin

Magnetic Resonance in Medicine, 05/11/2012

In addition to known glomerular labeling, confocal and MRI suggest that intravenously injected CF labels the extracellular matrix of the hepatic sinusoid, extracellular glycocalyx of alveolar endothelial cells, and macrophages in the spleen. Liver T values suggest that CF is cleared by 7 days after injection. These results suggest that CF may serve as a useful contrast agent for detection of a number of structures and functions with minimal toxicity.
