(a) The labeling rate of PEG/PEI-modified SPIO: the signal was significantly reduced and the T2 relaxation time was gradually shortened along with the increasing of cells; 103 labeled cells could be displayed in MRI scanning (white arrow, the lower left one indicated the nonlabeling group, and the cells in each tube were increased clockwise)
(b) The labeling rate of PEG/PVP-modified SPIO: the signal was significantly reduced and the T2 relaxation time was gradually shortened along with the increasing of the cells; 103 labeled cells could be displayed in MRI scanning (white arrow, the left one indicated the nonlabeling group, and the cells in each tube were increased clockwise)
