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]
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.
They form the lower part of the back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and quadrupeds, such as horses, pigs, or cattle. These bones are found in particular cuts of meat, including tenderloin or sirloin steak.
MRI is a newer technique used to diagnose spondylolysis and is favorable for a few reasons. The MRI is much more accurate than the x-ray and also does not use radiation. The MRI uses powerful magnets and radio frequencies to produce very detailed images of many different densities of tissue including bone and soft tissues. [13] [16]
MRI imaging appears to be the gold standard for diagnosing a tethered cord. [16] [17] A tethered cord is often diagnosed as a "low conus". The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus ...

MRI has become the most frequently used study to diagnose spinal stenosis. The MRI uses electromagnetic signals to produce images of the spine. MRIs are helpful because they show more structures, including nerves, muscles, and ligaments than seen on X-rays or CT scans. MRIs are helpful in showing exactly what is causing spinal nerve compression.
