This work investigated macrophages labeled with magnetosomes for the possible detection of inflammations by MR molecular imaging. Pure magnetosomes and macrophages containing magnetosomes were analyzed using a clinical 1.5 T MR-scanner. Relaxivities of magnetosomes and relaxation rates of cells containing magnetosomes were determined. Peritonitis was induced in two mice. T-1, T-2 and T-2* weighted images were acquired following injection of the probes. Pure magnetosomes and labeled cells showed slight effects on T-1, but strong effects on T-2 and T-2* images. Labeled macrophages were located with magnetic resonance imaging (MRI) in the colon area, thus demonstrating the feasibility of the proposed approach. (C) 2006 Published by Elsevier B.V.
