Canine Diagnostic Imaging Clinical Studies

The Diagnostic Imaging service at the Ontario Veterinary College (OVC) consists of radiologists who are specially trained to interpret x-rays, MRIs, CT scans, and other specialized images of all species. Findings from these studies are integral to the diagnosis, treatment, and follow up of your pet. To learn more about the diagnostic imaging service at the OVC, please click here.

ON HOLD FOR RECRUITEMENT – Evaluating the Effect of Minimally Invasive Surgery on the Intracranial Pressure in Dogs

Complete Title: The Effect of Laparoscopy on Intracranial Pressure as Measured by Optic Nerve Sheath Diameter

Study Investigator: Dr. Ryan Appleby

The optical nerve sheath contains cerebral spinal fluid and when intracranial pressure increases, the walls of the sheath stretch and expand. Using ultrasound, we can measure these changes in the optic nerve sheath diameter (ONSD). Gaining a better understanding of intracranial pressure changes in dogs may have a future impact on anesthetic considerations and surgical planning for laparoscopic procedures in veterinary medicine.

Inclusion Criteria:

  • Any dogs undergoing laparoscopic gastropexy and/or spay at OVC
