In the lumbar spine it is commonly used to treat spinal claudication caused by spinal stenosis, and is considered the most effective treatment for this condition based on current evidence. [3] In the cervical and thoracic spine it is used to treat myelopathy caused by compression of the spinal cord itself.
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
In patients with a high suspicion of radiculopathy due to lumbar disc herniation, yet the MRI is equivocal or negative, nerve conduction studies are indicated. [44] T2-weighted images allow for clear visualization of protruded disc material in the spinal canal.
Schmorl's nodes are fairly common, especially with minor degeneration of the aging spine, but they are also seen in younger spines. Schmorl's nodes often cause no symptoms, but may simply reflect that "wear and tear" of the spine has occurred over time; they may also reflect that bone strength was at one time somewhat compromised, perhaps due to a vitamin D deficiency although this has yet to ...
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.
MRI provides better resolution of tissue density, absence of bone interference, multiplanar capabilities, and is noninvasive. Plain films may show bony erosion of the spinal canal or of the sacral foramina. [citation needed] On MRI pictures, the signal is the same as the CSF one. If MRI made with a contrast medium: [citation needed] The signal ...
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis.
A lumbar MRI can rule out lumbar radiculopathy. [6] Imaging like MRI/CT/x-ray can be used to rule out mass lesions (e.g. tumors) that could compress the LFCN. [2] [4] Magnetic resonance neurography (MRN) can be used to assess signal alterations along the LFCN. [12]
