Abstract
This paper describes an MR imaging method for determining magnetic susceptibility constants of solutions containing paramagnetic contrast agents. The method's validity is demonstrated on Gd(DTPA) and Dy(DTPA) water solutions. The method can be used for measurement of the volume magnetic susceptibility or concentration of contrast agents in biological tissues.
摘要
本文描述了一种用于测定含顺磁性造影剂溶液的磁化率常数的磁共振成像方法。该方法在钆（二乙三胺五乙酸）和镝（二乙三胺五乙酸）水溶液上的有效性得到了验证。该方法可用于测量生物组织中造影剂的体积磁化率或浓度。
