Figure 6. Magnetic resonance contrast properties of multiwalled carbon nanotubes are stable in vivo.

Figure 6

(A) Representative axial MR images of two breast tumors injected with either 100 µg MWCNT600 or MWCNTN-doped and subsequently exposed for 30 s to NIR laser. Arrows show the injection site. Images were collected at five timepoints: before injection, immediately after injection, immediately after laser treatment, 24 h after laser treatment, and 7 days after laser treatment (laser power: 3 W/cm2, 1064 nm wavelength). (B) T2 relaxation measurement of the tumor region was acquired using multislice multipulse sequence at the five different time points described in (A).
