Magnetic Fe2O3nanorods with low cell toxicity were successfully synthesized viaa wet-chemical method. In vivostudies with a rabbit model show that the nanorods exhibit excellent T2signal enhancement. This work demonstrates that magnetic nanorods may provide a new type of MR enhancement agent for use in biomedical applications. [ABSTRACT FROM AUTHOR]
