High resolution susceptibility weighted imaging (SWI) was used in comparison with other MR-contrasts at 7T in order to visualize iron-labeled C6-glioma cells in a rat model. Although even very low iron concentrations were detectable by SWI, no significant iron accumulation was found at the margin of advanced tumors, suggesting persistence of the iron particles at the site of the primary cells in the tumor center.
