Richard L. Griffin, Alexia L. McKnight, Amy Rucker, Scott D. Bennett, Deana M. Fiser Journal of Equine Veterinary Science December 2011 31 12 685-692 Plain radiographic imaging inadequately identifies soft-tissue pathology and only distinguishes chronic laminitis after the development of notable displacement of the distal phalanx. The window of opportunity for maximum response to treatment occurs before biomechanical failure of the lamellar attachment. Radiographic and magnetic resonance venograms allow vascular assessment of patients affected with acute laminitis. When vascular findings are interpreted with additional magnetic resonance information, the degree of damage to the foot in patients affected with laminitis is understood more thoroughly. This article describes the technique, findings, and outcome in a group of laminitic horses that underwent contrast magnetic resonance imaging.
