FIG. 4.

r 2 NMRD profile of the Gd-SWCNTs. Circles represent experimental data and solid lines the best fit obtained using SBM theory.

Image of FIG. 5.
FIG. 5.

Contrast-enhanced T 1-weighted (gradient echo sequence; repetition time (TR) = 66 ms, echo time (TE) = 3 ms, flop angle = 108°) MRI phantom images of Gd-SWCNT (green circle), and Gd-DTPA (Magnevist, purple circle) solutions dispersed in 4% gelatin (4 g of gelatin in 100 g of distilled water). Both phantoms have equimolar concentrations of gadolinium ([Gd3+] = 0.22 mM).
