Title: Assessment of radiographic positioning for the diagnosis of navicular disease in the horse. Author: Rose RJ. Journal: J S Afr Vet Assoc; 1981 Jun; 52(2):135-8. PubMed ID: 7277373. Abstract: Three of the standard radiographic views of the navicular bone 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 degrees 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 1 1000 mm, and a tube-head angle of 50 degrees 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 centred 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.[Abstract] [Full Text] [Related] [New Search]
