Radiographic evaluation of suspected spinal condition begins with an x-ray A herniated disc, being composed of soft tissue instead of bone are not visible on X-rays, but can appreciate other associated changes, such as the characteristic bony ridges of cervical spondylosis. Also, can be accurately align the disks.
Magnetic resonance imaging (MRI) has become in many cases the study of choice in cases of herniated disc.
Its superior resolution of soft tissues gives good definition of disc material, cord compression and compression of the nerve roots. When the bone detail is required it is desirable to perform a CT scan with intrathecal contrast.
