Spinal disc protrusion visible in MRI [1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure.
With a diagnostic accuracy of 97%, it is the most sensitive study to visualize a herniated disc due to its significant ability in soft tissue visualization. MRI also has higher inter-observer reliability than other imaging modalities. It suggests disc herniation when it shows an increased T2-weighted signal at the posterior 10% of the disc.
Typical radiographic findings include disc space narrowing, displacement of vertebral bodies, fusion of adjacent vertebral bodies, and development of bone in adjacent soft tissue (osteophyte formation). An MRI is typically reserved for those with symptoms, signs, and x-ray findings suggesting the need for surgical intervention.
The cause is usually a disc herniation in the lower region of the back. [1] Other causes include spinal stenosis, cancer, trauma, epidural abscess, and epidural hematoma. [1] [2] The diagnosis is suspected based on symptoms and confirmed by medical imaging such as MRI or CT scan. [1] [3] CES is generally treated surgically via laminectomy. [1]
MRI of a lumbar spinal stenosis L4-L5. L4-L5 antherolisthesis of grade I. Hypertrophy of interspinous ligaments in relation to Baastrup's disease. 67 years old man. MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic, and lumbar.
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.
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.
Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. In this article, the term is used to describe a lumbar herniated disc.
