Once delivered to the heart, injected cells are difficult to distinguish from target tissue by MR in vivo.To specifically imaging injected cells in MR, the recent investigation generally using superparamagnetic iron oxid to label MSCs, which should enable serial tracking and quantification of MSC transplantation noninvasively by MR.

由于MR成像无法区分移植细胞和靶组织细胞，为使移植细胞能在MR上特异性显示，目前广泛使用超顺磁性氧化铁(superparamagnetic iron oxid， SPIO)作为负性标记物标记移植细胞，进行MR体外和活体内的成像研究。

In order to expand the application of MRI contrast agent in clinical studies, in this paper the lyophilized SPIO was prepared.

为进一步拓展MRI造影剂在国内的临床应用，本文制备了注射用超顺磁性铁氧体纳米微粒。
