Abstract
Objectives The aim of this study was to describe how the addition of contrast-enhanced low-field
magnetic resonance imaging sequences can confirm or change the initially planned surgical
approach for canine intervertebral disc extrusions.
Study Design Magnetic resonance imagings of 20 dogs diagnosed with intervertebral disc extrusions
were retrospectively reviewed by a board-certified neurologist for the location of
extradural disc material, contrast enhancement, and whether enhancement reinforced
or changed the initially planned surgical approach.
Results Extradural compressive material contrast-enhanced in 17/20 dogs. In 14/20 dogs, enhancement
was considered to increase the confidence level of the location for surgery including
two cases where the surgical approach was altered.
Conclusion Gadolinium-based contrast agents in low-field magnetic resonance imaging can aid
the surgical planning of intervertebral disc extrusions in dogs by improving the confidence
level of location and extent of extradural material and occasionally altering the
surgical approach.
