Radiographs of mouse hind legs before and after gold nanoparticle injection. (a) Before injection. (b) 2 min after i.v. gold injection (2.7 g Au/kg). Significant contrast (white) from the gold is seen in the leg with the tumor (arrow) compared with the normal contralateral leg. 6 s exposures at 22 kVp and 40 mA s.
