Subtraction radiography for the diagnosis of bone lesions in dogs. Report for 1982-1984

Resolution of osseous wounds utilizing conventional radiographic techniques is dependent upon favorable angulation without superimposition of dense anatomical structures. A technique of computer subtraction utilizing sequential radiographs has been demonstrated to enhance visualization of such defects in dry skulls, but usefulness in live animals had heretofore not been demonstrated. This investigation demonstrated the usefulness of computer subtraction radiography in live animals, both error rate and diagnostic time being reduced significantly.
