An enhanced visibility composition for implantation from a remote source, so that the composition can be readily observed under fluoroscopy or other imaging techniques. The compositions include a biocompatible matrix, such as a hard tissue implant material for example, and radiopaque particles mixed in the matrix. The radiopaque particles have a particle size between about 120mu and 2200mu, more preferably about 350mu and 2200mu, even more preferably between about 450mu and 1600mu, and most preferably between about 570mu0 and 1150mu. Preferably the hard tissue implant and the radiopaque particles are formed or prepared in a slurry. Optionally, the enhanced visibility composition may further include additional radiopaque particles or contrast particles mixed in with the composition, which have a particle size between about 120mu and 350mu, preferably between about 120mu and 250mu.
