aWe previously applied ferumoxytol as an intravenous contrast agent for MR imaging of arthritis and we performed initial ferumoxytol-labeling experiments of hMSCs and other stem cells 我们早先申请了ferumoxytol作为一个静脉内对比代理为关节炎的想象先生,并且我们执行了hMSCs和其他干细胞的最初的ferumoxytol标记的...
MRI is also able to quantify water diffusion within tissues. Strong field gradients applied on each side of a 180° refocusing pulse cause diffusion-mediated signal attenuation due to phase dispersion of spins. Conversely, in static tissue, the effect of both gradients cancels out and the signal ...
