See explanation of utilizing Computerized Tomography (CT) for diagnosis of IVDD.
Numerous imaging modalities can be used to diagnose IVDD. Plain radiographs (X-rays) are a useful screening tool but usually are not accurate in obtaining a conclusive diagnosis. Computerized tomography (CT) is the gold standard for cervical or thoracolumbar IVDD diagnosis in small breed dogs. Contrast media is often used in conjunction with CT imaging. Magnetic resonance imaging (MRI) is also used to diagnose canine spinal disorders but is most applicable in large breed dogs, lumbosacral IVDD and neoplasia.
