Topic:Diagnostic Imaging
Diagnostic imaging in horses encompasses a range of techniques used to visualize the internal structures of the equine body for the purpose of diagnosis and treatment planning. These techniques include radiography, ultrasonography, magnetic resonance imaging (MRI), computed tomography (CT), and nuclear scintigraphy. Each modality offers unique advantages in assessing different tissues and conditions, such as bone fractures, soft tissue injuries, and joint abnormalities. Radiography is commonly employed for evaluating bone structures, while ultrasonography is frequently used for soft tissue assessment. MRI and CT provide detailed cross-sectional images, facilitating the examination of complex anatomical regions. Nuclear scintigraphy can detect areas of increased bone activity, often used in lameness evaluations. This page compiles peer-reviewed research studies and scholarly articles that explore the applications, advancements, and comparative effectiveness of diagnostic imaging modalities in equine veterinary practice.
Transposition of the aorta and atresia of the pulmonary trunk in a horse. ABSTRACT Transposition of the aorta to the right ventricle with atresia of the pulmonary trunk was described in a 2 year old horse. Clinical and physiological examinations were performed and data recorded. Teratogenesis of the present anomaly was discussed and the literature reviewed. The probable course of circulation during the fetal life and after birth of this animal was suggested. An extensive col-lateral circulation was developed to the lungs, which might explain how the animal could live so long.
Chip fractures in the carpus of the horse: a radiographic study of their incidence and location. The incidence of chip fractures in carpal bones and the distal end of the radius in the horse was determined. The radial carpal bone was involved 50% of the time, with the distal end of the radius and intermediate and 3rd carpal bones being involved less frequently. Nine locations were designated where chip fractures in the carpus occurred most often.
A higher incidence of fractures was noticed from the right carpus, with slab fractures of the 3rd carpal bone being noticed more frequently on the right front limb.
Congenital defects in domesticated animals: general considerations. A mass survey of the distribution of congenital defects in various types of livestock was made possible by the processing by the Veterinary Medical Data Program (VMPD) of standard observations collected on 137, 717 patients seen at veterinary college clinics between Mar. 1964 and Jan. 1969. A total of 6455 animals with 1 or more congenital defects was found. The data were analysed according to species, institution and organ system. Pigs had the highest proportion of congenital defects, cats the lowest. Over all, the systems most frequently involved were the musculo-skeletal and urogenital. The...
Comparative studies on the haemolytic and Treponema pallidum immobilizing complement activity in the serum of different species. Complement activity in the serum of eight species has been studied in two ways: by immobilization of sensitized with human or rabbit antibody and by haemolysis of sheep red cells sensitized with rabbit antibody. Serum of the pig, monkey and man was actively haemolytic but contained a heatlabile factor that immobilized unsensitized in the presence of guinea-pig complement and precluded the detection of immune immobilizing activity. Sera of other species, although without action on unsensitized treponemes, even with added guinea-pig complement, differed in their relative haemolytic and immobil...
