丝裂霉毒C铁磁性微球磁响应性能的研究

Responsiveness of Ferromagnetic MMC-bearing Microspheres

考察了自制的磁性微球的体外物理栓塞及动物体内栓塞情况，研究了外加磁场对微球体内分布的影响。结果表明：该微球具有良好的磁响应性能，在磁场作用下能滞留、栓塞于靶位；外加磁场能改变微球在体内的分布。

Embolization by ferromagnetic microspheres was studied both in vitro and in vivo. It was demonstrated that the microspheres which were readily concentrated at targeted site showed strong magnetic responsiveness.Distribution of(125)￣I-labelled microspheres varied with presence or absence of magnetic field.
