A lumbar MRI specifically examines the lumbar section of your spine — the region where back problems commonly originate. The lumbosacral spine is made up of the five lumbar vertebral bones (L1 thru L5), the sacrum (the bony “shield” at the bottom of your spine), and the coccyx (tailbone).
What is the average cost of a lumbar spine MRI?
The price of a lumbar MRI is influenced by several factors such as the facility/hospital you choose, whether or not any insurance is available, the geographical location, and whether or not a contrast substance will be used.

Which is worse bulging or herniated disk?
Compared with a bulging disk, a herniated disk is more likely to cause pain because it generally protrudes farther and is more likely to irritate nerve roots. The irritation can be from compression of the nerve or, much more commonly, the herniation causes a painful inflammation of the nerve root.
What is a lumbosacral spine MRI?

How does an MRI work?
The MRI machine uses a strong magnetic field that aligns and stimulates particles called protons in the body, for cing them to spin out of alignment. When the technician halts the magnetic field, the protons begin to spin in their usual way. As they do this, they give off energy that the MRI machine detects.

What is the MRI of the lumbar spine?
An MRI scan of this area is used to accurately depict soft tissue in and around the lumbosacral spine. Measurements mainly focus on a change in signal intensities and less on absolute distances or angles. Various pathologies affect the configuration of the soft tissue, which can lead to clinical symptoms such as neural compression syndromes, most commonly due to degeneration, congenital disorders, and benign or malignant neoplasms. Structures visible on MRI include neural structures, meninges, cerebrospinal fluid, blood vessels, fat, ligaments, bone and joints, discs, muscles, and organs. Knowledge of normal anatomy and the systematic assessment of these structures will help to generate the most accurate and clinically relevant scan interpretation. In addition, it is important to have a clinical question in mind before requesting and assessing a lumbosacral MRI, since, for example, degenerative abnormalities are common and asymptomatic in the majority of people. More importantly, among patients without clinical signs pointing toward a specific condition, imaging does not improve patient outcomes and may lead to worse outcomes, unnecessary harm, and increased costs.

How many vertebrae are in the lumbar spine?
Before deciphering the abnormalities listed in the lumbar MRI report, it’s important to understand the normal anatomy. The lumbar spine consists of bones (usually five vertebral bodies) stacked on top of each other and separated by five discs. The vertebral bodies are usually labeled 1 through 5, and the discs are named by the bones above and below.
What are the problems with the lumbar spine?
Problems in the Lumbar Spine. As we get older, changes occur naturally in the spine. The discs tend to lose their water content (desiccate). The annulus of the disc may bulge, protrude or herniate. The bones may develop bone spurs (osteophytes). The ligamentum flavum may enlarge (hypertrophy).
What is the L5-S1 disc?
Therefore the L4 and L5 vertebral bodies are separated by the L4-5 disc. Just below the lumbar spine is the sacrum so the bottom disc is called L5-S1. This normal configuration is reported in the MRI report as both sagittal and axial depictions. The sagittal view is a profile picture. The axial view is a cross-section.

The back side of the spine is more bone called the lamina and spinous process. The nerves go to specific regions of the leg. The L1 and L2 nerves tend to go to the groin region. The L3 nerve to the front of the thigh. The L4 nerve to the shin and instep. The L5 nerve to the top of the foot and big toe.
What nerve is the L5 nerve?
The L5 nerve to the top of the foot and big toe. The S1 nerve to the outside and bottom of the foot. The disc normally is composed of 2 parts. These are microscopic and cannot exactly be differentiated on an MRI. The central softer part of the disc is the nucleus and the out layer is the annulus.
Where does the spinal cord end?
The spinal cord itself ends around the T12-L1 level , but the nerves continue down the lumbar spine as the cauda equina. At each disc level, a nerve exits the spine and goes to a specific region of the leg. The back side of the spine is more bone called the lamina and spinous process.

Suspected intervertebral hernia or protrusion of vertebrae in the lumbosacral region as a result of damage to the fibrous ring.
Which part of the spine is mobile?
Of the 3 parts of the lower spine in adults, only the lumbar is mobile. In children and adolescents, the sacral region also has some mobility, whose vertebrae grow together only in adolescence. The tailbone is considered a rudimentary body, inherited from tail ancestors and eventually lost its relevance.
What is the purpose of magnetic resonance examination of the sacral section?
In order to understand under what diseases and symptoms a doctor may suggest a magnetic resonance examination of the sacral section, it would be helpful to understand the structure of the lower part of the spine. At the same time, it is not at all necessary to delve into the evidence-based framework, but rather recall the information from the school course of anatomy.
