Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
This procedure is to look for the level of spinal cord disease such as lumbar nerve root compression, cauda equina syndrome, conus medullaris lesions, and spinal stenosis. This is done for those who are unwilling or unable to do MRI scan of the spine. Lumbar puncture is done before injected contrast into the thecal sac.
MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic, and lumbar. [ 19 ] [ 20 ] MRI is useful to diagnose cervical spondylotic myelopathy (degenerative arthritis of the cervical spine with associated damage to the spinal cord). [ 21 ]

I acknowledge that getting this scan is a major expense, and a privilege, as their scan prices start at $1,000. I should also note that not all experts think a full-body MRI scan is totally necessary.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
Lumbar disc herniation occurs 15 times more often than cervical (neck) disc herniation, and it is one of the most common causes of low back pain. The cervical discs are affected 8% of the time and the upper-to-mid-back (thoracic) discs only 1–2% of the time.
Therefore, contrast is injected into the spinal canal via lumbar puncture and then imaged using CT scan (known as CT myelography). CT myelography is useful when the person is contraindicated to MRI scan due to presence of pacemaker or infusion pump in the body. [2] MRI is the investigation of choice to investigate radiculopathy and myelopathy.
