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 120 mu and 2200 mu , more preferably about 350 mu and 2200 mu , even more preferably between about 450 mu and 1600 mu , and most preferably between about 570 mu and 1150 mu . 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 constrast particles mixed in with the composition, which have a particle size between about 120 mu and 350 mu , preferably between about 120 mu and 250 mu .
