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 ...

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
The former is the most common, causing low back pain (lumbago) and often leg pain as well, in which case it is commonly referred to as sciatica. 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 most common forms are lumbar spinal stenosis, at the level of the lower back, and cervical spinal stenosis, which are at the level of the neck. [12] Thoracic spinal stenosis, at the level of the mid-back, is much less common. [13] In lumbar stenosis, the spinal nerve roots in the lower back are compressed which can lead to symptoms of ...
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.
Despite this, the use of imaging in low back pain has increased. [10] Some low back pain is caused by damaged intervertebral discs, and the straight leg raise test is useful to identify this cause. [5] In those with chronic pain, the pain processing system may malfunction, causing large amounts of pain in response to non-serious events. [11]
In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm.
