Abstract
Of the standard radiographic views of the navicular bone, 3 were assessed in normal horses and horses with navicular disease to determine the most effective radiographic positioning. Using the upright pedal view, a pastern angulation of 20.degree. from the vertical produced the optimum result when radiographs were taken using a grid. The best result using the high coronary view was obtained with an anode-film distance of 1000 mm, and a tube-head angle of 50.degree. from the vertical. When the special navicular view described by Morgan was examined, the most satisfactory projection was obtained using an anode-film distance of 900 mm, a tube-head angle of 55.degree. and the primary beam centered between the bulbs of the heel. For the diagnosis of navicular disease, a combination of the upright pedal view and the special navicular view appears most effective.
