State-of-the-Art Digital Imaging Technology Columbia Equine Hospital

There will be times in the course of your horse’s life that your animal will require imaging services of some kind in order to identify any medical problems that a physical examination cannot uncover. At Columbia Equine Hospital, we have a number of advanced imaging technologies available for the health of your horse.

Digital Radiography (X-rays)

Digital Imaging Technology at Columbia Equine HospitalWe are able to take high-quality digital X-rays in the hospital or in the field. We use TruDR by Sound Technologies to deliver instant enhanced digital radiographs. Our portable digital radiography unit allows immediate evaluation of positioning, exposure, and motion to ensure quality radiographs and eliminate the need for retakes and multiple farm trips. With TruDR, pre-purchase exams are accomplished thoroughly and efficiently with less radiation exposure for handlers and the horse. Veterinarians, staff, and clients may instantly review images, allowing rapid diagnosis and treatment. The images are digitally archived and automatically loaded on a secure website to allow web-based sharing between clients, their farriers, and other veterinarians. Digital radiographs can be taken at your farm or in our Gresham hospital.

Nuclear Scintigraphy (Bone Scan)

Nuclear scintigraphy is available at Columbia Equine Hospital. This advanced diagnostic tool allows veterinarians to evaluate the entire equine skeleton (or region), making it an ideal tool for diagnosing difficult or multi-factorial lameness. Scintigraphy involves the use of a bone-seeking isotope that is concentrated in areas of increased bone activity that is found with arthritis, infection, fracture, or soft tissue injury that is closely associated with bone.

Bone scan, in conjunction with more traditional diagnostics, is another tool available to provide a more thorough and sensitive diagnosis of discrete lamenesses. The scintigraphy scans are useful for diagnosis of elusive lower limb lameness and upper limb/axial skeletal (back, neck, pelvis, shoulder) injuries that cannot be evaluated with radiographs. Scintigraphy localizes lameness and performance-limiting injuries that do not block, that block but are radiographically "silent," and that are multifocal.

Our MIE digital unit with a Siemens Large Field of View Digitrac Gamma Camera is state-of-the-art and allows for all of the advantages of the new digital format. The updated motion correction software and high-resolution collimator allow for pristine diagnostic images. The large field of view allows for faster studies and better comparisons of anatomic areas.

Bone scans are performed on a standing sedated horse. The camera moves around the horse on a rolling gantry system that is quiet and easily adjusted to a variety of positions. The Gamma camera counts the isotopes that concentrate in these areas and converts the counts into an image. All scintigraphy studies can be sent via email and on a CD, which enable specialists as well as referring veterinarians to receive these images digitally.

Our veterinarians interpret the images and write a report, which includes the findings of the scan and recommendations for further diagnostics and/or treatments.

To know when scheduling a nuclear scintigraphy for your horse:

  • Front shoes will be removed with a full body or front half scan
  • Your horse will be at Columbia Equine Hospital for at least three days
  • Your horse should not have had any injections into a joint or a nerve within two weeks prior to the scan


This non-invasive high-resolution diagnostic tool allows your veterinarian to evaluate soft tissue of all types. We have two state-of-the-art ultrasound units used for evaluation of lameness cases, as well as other deeper soft tissue structures. Diagnostic ultrasound includes a digital 3D image that greatly improves diagnostic capability while easing the digital transfer of images for referral and evaluation. Digital ultrasound images can be taken on your farm or in our Gresham hospital.

Ultrasound is useful for evaluation of:

  • Soft tissue structures of the legs, tendons, and ligaments
  • Abdomen for colic, intestinal motility, and obstructions
  • Urinary system, to identify bladder and kidney stones
  • Respiratory system, lungs, and pleural space
  • Reproductive system
  • Ultrasound-guided injections of the cervical facets (neck vertebrae) and the sacroiliac joint


A fiber optic endoscope is a long, narrow tube with a tiny camera at the tip. Our veterinarians perform endoscopic examinations to evaluate the esophagus, upper airway (to examine the trachea and main airways). Endoscopic procedures are usually non-invasive and only require the horse to be lightly sedated.

“I can not begin thank Dr. Hanson and staff for the amazing care they gave my horse...”

“My initial conversation was with Alexis, me asking a lot of questions, she providing a lot of professional answers and setting up an appointment for a farm visit later that day, to Dr. Rioux-Forker showing up on time, listening to the problems we are having with our OTTB, Leon, asking thoughtful questions, and suggesting helpful solutions, we were very happy with every interaction we had with the staff at Columbia Equine Hospital. Very helpful. Very professional. Very experienced. And reasonably priced. Thank you!”
