Figure 8From: Synthesis route and three different core-shell impacts on magnetic characterization of gadolinium oxide-based nanoparticles as new contrast agents for molecular magnetic resonance imagingSignal intensities for contrast agents . Relative signal intensities in (a) Gd-DTPA and Gd2O3-DEG. (b) SPGO-mPEG-silane550 and SPGO-mPEG-silane2000 (TR = 600 ms and TE = 15 ms). Maximum signal intensity for Gd2O3-DEG was obtained (0.6 mM), whereas it was 1.5 mM for Gd-DTPA.Back to article page
