Magnetic Particle Imaging: Kinetics of the intravascular signal in vivo

The highest spectral MPI signal was measured directly after Resovist
^®
administration (3,21*10
⁻⁹
Am2Hz
⁻¹
). After application of Resovist
^®
the signal decreased to 39.7 % within 5 minutes and to 20.5 % and 12.1 % within 10 and 15 minutes, respectively (see Fig. 1). Within 30 minutes, the measured signal was below the background noise level.
