Commonly referred to as “x-rays”, radiographs are used widely in the horse for examination of distal limbs in the field. Our powerful in-hospital x-ray unit is capable of radiographing neck, chest and proximal limbs in the standing horse. Thicker body parts such as pelvis and spine can be radiographed in the anesthetized patient.
Philips IU-22 and ATL-5000
Sonography is commonly to evaluate the soft tissues structures of the equine limb as well as the thorax and abdomen.
Computed Tomography (CT)
Toshiba Aquilion Large-Bore, 16-slice
CT scanning uses x-ray and sophisticated computer processing to render cross-sectional images of the body. General anesthesia is necessary for all equine examinations and is most commonly used to evaluate the head, teeth and distal limbs.
Magnetic resonance imaging (MRI)
Toshiba Vantage Atlas 1.5 Tesla
MRI examines body structures using the property of nuclear magnetic resonance to stimulate with radiofrequency energy the nuclei of hydrogen atoms aligned in a strong magnetic field and detect those signals for imaging. MRI provides excellent contrast between soft tissues that are otherwise indistinguishable by other means, which makes it especially useful in imaging the musculoskeletal (muscles, tendons, ligaments) systems, particularly the structures within the hoof capsule.
In nuclear medicine imaging, radiopharmaceuticals are injected into the animal and a gamma camera detects the distribution of the isotope in the body. These examinations are used mainly for the diagnosis of bone lesions in the horse including osteoarthritis, stress fractures and occult causes of lameness. The radiation dose from the isotope is minimal and use is fully regulated by Environmental Health and Safety at Cornell and the New York State Health Department.
The “C-arm” systems permit fluoroscopy in the operating room during surgery for real-time guidance in orthopedic repairs.
