T2 weighted images (top row), and false color T2 maps (bottom row) from left to right, before, and 12, 16, and 36 h after adoptive transfer of T cells primed against an antigen expressed on the tumor in the right flank but not expressed in the tumor on the left flank of a mouse. Dark areas represent location of T cells, quantified per voxel in the bottom panel. Prior to intravenous injection, cells were labeled with an iron oxide nanoparticle, allowing their noninvasive visualization over time by MRI (from Cancer Res. vol. 63, no. 20, pp. 6838-6846, Oct. 2003, reprinted with permission).
