  • Title: Contrast-Enhanced Low-Field MRI Occasionally Alters the Surgical Approach for Canine Intervertebral Disc Extrusions.
    Author: Craciun I, Khan S, Hughes J, Freeman P.
    Journal: Vet Comp Orthop Traumatol; 2022 Sep; 35(5):347-350. PubMed ID: 35732181.
    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.
