We have assessed murine microglia cells (Bv-2) and human teratocarcinoma cells (NT2) for future use with a novel bimodal MR contrast agent. These cells can be used to identify regions of neurodegeneration. To evaluate contrast enhancement, we have compared the performance of our bimodal agents consisting of Dy-label quantum dots to SPIOs and Dy chelates (DOTA and DTPA).
