超顺磁性氧化铁(SPIO)颗粒由于其较强的磁化强度,在梯度回波图像上产生信号空洞区域。在实践中,信号空洞区域可能与空气产生的空洞区域难以区分。然而,SPIO对外加磁场的响应是非线性的。SPIO的磁化强度在1特斯拉左右达到饱和,而水和空气的磁化强度随着场强的增加而线性增加。体模实验和小鼠实验证明了一种无歧义识别超顺磁性造影剂的可行性。
Superparamagnetic iron oxide (SPIO) particles generate signal void regions on gradient echo images due to their strong magnetization. In practice, the signal void region might be indistinguishable from that generated by air. However, the response of SPIO to an externally applied magnetic field is non-linear. Magnetization of SPIO saturates at around 1 Tesla while magnetization of water and air increase linearly with field strength. Phantom experiment and mice experiments demonstrated the feasibility of a non-ambiguous identification of superparamagnetic contrast agents.
