Standing computed tomography is feasible and has clinical utility in ruminants
Objective:
To demonstrate the feasibility and clinical utility of standing CT in ruminant species.
Animals:
Medical records of ruminants that underwent standing CT from January 2019 through August 2025 were reviewed.
Clinical Presentation:
9 cases met inclusion criteria. Cases included bovine (n = 7) and small ruminants (2). There were 7 males and 2 females. Ages ranged from 3 to 84 months. Weights ranged from 83 to 600 kg. Cases presented for a head tilt (n = 4), a submandibular mass (1), head shaking (1), and lameness (3).
Results:
Anatomic regions of interest imaged with CT included the head (n = 6) and distal limbs (3). A final imaging diagnosis was achieved in 8 of 9 cases. Diagnosis included otitis media (n = 4), mandibular lymph node abscess (1), stenosis of retroarticular foramen (1), septic arthritis (1), and fracture (1). Animals tolerated standing CT imaging well, and no complications were encountered.
Clinical Relevance:
Sedated standing CT of the head and distal limbs is feasible in ruminants and may be an option in patients that are amenable to a standing imaging procedure.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
