Imaging techniques in horses encompass a range of diagnostic tools used to visualize the internal structures and systems of equine patients. These techniques assist in the diagnosis, monitoring, and treatment planning of various conditions affecting horses. Common imaging modalities include radiography (X-rays), ultrasonography, magnetic resonance imaging (MRI), and computed tomography (CT). Each technique offers unique advantages in terms of resolution, depth of penetration, and the type of tissues that can be examined. For instance, radiography is frequently used for assessing bone structures, while ultrasonography is often employed for soft tissue evaluation. MRI and CT provide detailed cross-sectional images, aiding in the assessment of complex anatomical regions. This page compiles peer-reviewed research studies and scholarly articles that explore the application, advancements, and comparative efficacy of imaging techniques in equine veterinary medicine.
ALEXANDER F, BENZIE D.1. The disposition and surface relations of the alimentary tract of the foal have been studied radiographically.
2. The rate of progress of a barium meal through the digestive tract was determined. The barium traversed the stomach and ileum of the weaned foal faster than that of the suckling foal, but was longer retained in the cæcum and ventral colon of the weaned foal.
This study was designed to investigate whether horses with clinical signs of back pain due to suspected soft tissue injuries were affected by polysaccharide storage myopathy (PSSM). Diagnosis of PSSM in muscle biopsies obtained from the M. longissimus lumborum of 5 showjumpers and 4 dressage horses with a history of back pain is reported. M. longissimus lumborum biopsies of these horses were characterised histopathologically and in 3/9 cases also by electron microscopy. Observations were compared with M. gluteus biopsies of the same horses, and with M. gluteus biopsies obtained from 6 Standard...
Manso-Díaz G.Diagnostic imaging is essential for evaluating and managing neurologic disease in horses. Following clinical lesion, neurolocalization imaging modalities are often necessary to further characterize the disease process. However, which technology to use depends on various factors, including the patient's size, clinical signs, and the anatomic region. Current advances in imaging technology, in general, and the adaptation of different modalities for equine patients, in particular, have substantially improved our ability to evaluate the equine central nervous system. This article will summarize the...
Belova N, Malle A, Schieder K, Licka TF.For centesis of the equine navicular bursa radiographs confirming needle placement are recommended, this can be a logistical challenge. Therefore, we aimed to identify the usefulness of radiographic measurements for centesis of the navicular bursa. On lateromedial radiographs localization of the centre of the flexor surface of the navicular bone was determined in 26 isolated limbs. Based on these measurements, 21 novice veterinary students performed 130 needle placements using the axial distal palmar technique injecting one of five dyes per cadaver limb. Success was identified on dissection as...
Ahmed HT, Berner D, Zhang Q, Verheyen K, Llabres-Diaz F, Peter VG, Chang YM.Fractures are a leading cause of morbidity and mortality in Thoroughbred racehorses, posing a significant threat to their welfare and careers. This study introduces a deep learning model specifically designed to facilitate fracture detection in equine athletes. By leveraging extensive training on human fracture data and refining the model with equine imaging, it highlights the transformative potential of transfer learning across species and medical contexts. This approach is not limited to equine fractures but could be adapted for use in detecting injuries or conditions in other veterinary spe...
Bostick HN, Keys DA, Bowden AC, McMullen RJ.To compare equine optic nerve head (ONH) measurements using spectral domain optical coherence tomography (SD-OCT) to detect clinically relevant ONH cupping. Methods: Forty-five eyes from 34 horses were categorized as CONTROL or CUPPED based on indirect ophthalmoscopy and were measured using SD-OCT: Bruch's membrane opening (BMO), optic cup width (OC), anterior laminar depth (ALD), prelaminar thickness (PLT), and cup-to-disk ratio (OC: BMO) at superior (sup.), central (ctr.), and inferior (inf.) ONH locations. Results: The OC:BMO was 0.61 ± 0.09 (sup.), 0.64 ± 0.09 (ctr.), and 0.55 ...
Erdoğan MS.Radiographic measurement parameters play a key role in diagnosing acute and subacute laminitis in horses, with diagnostic thresholds typically derived from empirical receiver operating characteristic (ROC) analysis. However, these methods often produce unstable results, particularly in small or noisy datasets. This study applies nonuniform rational B-spline (NURBS)-based ROC smoothing to radiographic data from laminitic and healthy horses to evaluate its effectiveness in refining diagnostic thresholds. Thresholds are determined using Youden's index based on NURBS-smoothed ROC curves and compar...
Szara T, Hadžiomerović N, Bakıcı C, Güzel BC, Gündemir O, Gündemir O.Three-dimensional geometric morphometric methods have emerged as a pivotal tool in veterinary anatomy, taxonomy, clinical research, and studies of morphological diversity. This article summarizes the key stages, applications, clinical potential, and recommendations for data standardization in 3D morphometrics. Datasets are typically acquired using radiological modalities, including computed tomography (CT), magnetic resonance imaging (MRI), and 3D surface scanning, each offering specific advantages and constraints contingent on the research context. Standardized landmark sets are essential in ...
