What Is Spinal MRI and What Does It Show
Spinal health is a critical aspect of our overall well-being. When issues arise within the spine, they can lead to various discomforts and impairments in daily life. To diagnose these problems accurately, medical professionals often turn to Spinal MRI (Magnetic Resonance Imaging).
This article will explore Spinal MRI, including what it is, how it works, and what valuable insights it can provide into the health of your spine. It will also discuss the importance of MRI of the thoracic spine and cervical spine and the differences between MRI scans with and without contrast.
Understanding Spinal MRI
Spinal MRI, or Magnetic Resonance Imaging of the Spine, is a non-invasive medical imaging technology that generates extensive pictures of the spinal cord, vertebral bones, discs, and surrounding soft tissues using high magnetic fields and radio waves. MRIs, unlike X-rays and CT scans, which employ ionizing radiation to obtain high-resolution pictures, depend on the magnetic characteristics of the body’s atoms. This makes it a more secure alternative, especially for routine usage in detecting spinal disorders.
How Does Spinal MRI Work?
Spinal MRI functions based on the behavior of hydrogen atoms within the body when subjected to a magnetic field. Here’s a simplified breakdown of the process:
Alignment: When you enter the MRI machine, the strong magnetic field causes the hydrogen atoms in your body to align with it.
Pulse and Relaxation: A brief burst of radio waves is directed at your body, causing the hydrogen atoms to temporarily change their alignment.
Recovery: After the radio waves cease, the hydrogen atoms gradually return to their original alignment, emitting signals in the process.
Signal Reception: Specialized coils in the MRI machine detect these signals and transmit them to a computer.
Image Creation: The computer processes the signals to create highly detailed cross-sectional images of the spinal structures.
This technology allows for precise visualization of the spinal cord, nerves, intervertebral discs, and any abnormalities or pathologies that may be present.

What Does an MRI Scan of the Spine Show?
Now that we understand the basics of Spinal MRI. Let’s delve into what information it can provide about your spine:
- Disc Herniation
Disc herniation is a common ailment in which the inner, gel-like substance of a spinal disc protrudes through the outer layer. It can easily be detected by MRI images. This might put pressure on surrounding nerves, resulting in discomfort, tingling, or weakening.
- Spinal Stenosis
Spinal stenosis, a disorder marked by the narrowing of the spinal canal, is easier to identify using MRI. The spinal cord or nerve roots may be compressed by this constriction, leading to discomfort and decreased movement.
- Tumors
MRI scans can detect both benign and malignant tumors within the spinal column. These tumors may develop within the vertebrae, spinal cord, or adjacent tissues.
- Infections and Inflammatory Conditions
MRI is sensitive to inflammation and can identify conditions such as infections or inflammatory diseases that affect the spine.
- Fractures and Trauma
MRI is effective in detecting fractures, especially in the early stages when X-rays may not reveal the injury. It also helps assess soft tissue damage associated with trauma.
MRI of the Thoracic Spine
The thoracic spine, located in the upper and mid-back region, plays a crucial role in providing stability and support for the ribcage. MRI of the thoracic spine is valuable for evaluating conditions such as:
Thoracic Disc Herniation: Assessing herniated discs in the thoracic region, which can cause chest or upper back pain.
Spinal Cord Injuries: Identifying injuries to the spinal cord and assessing the extent of damage.
Tumors: Detecting tumors or abnormal growths within the thoracic spinal region.
Cervical Spine MRI
The cervical spine, or neck region, is susceptible to various issues due to its flexibility and the constant movement it endures. A cervical spine MRI can help diagnose:
Cervical Disc Herniation: Identifying symptoms of herniated discs that can lead to neck pain, arm pain, or weakness.

Cervical Stenosis: Evaluating narrowing of the spinal canal that can compress the spinal cord, causing neurological symptoms.
Pinched Nerves: Locating compressed or pinched nerves in the neck that may be causing discomfort.
MRI with and without Contrast
In rare situations, a contrast agent, commonly gadolinium, may be given during a spinal MRI to improve the visibility of specific structures or abnormalities. This is known as an MRI with contrast. The decision to utilize contrast is based on the individual clinical condition and the information required.

MRI without Contrast: This is the standard MRI procedure. It provides detailed images of the spine’s anatomy, making it suitable for most diagnostic purposes.
MRI with Contrast: Before the scan, a vein is injected with the contrast agent. It aids in highlighting blood vessels, tumors, inflamed regions, or infected areas, making them more noticeable in the photographs.
While contrast-enhanced MRI can provide additional information in certain cases, it’s important to note that it may not be necessary for every patient.
What to Expect During the Spinal MRI
You will be requested to lie down on a portable exam table, which will then be placed inside the MRI machine for the Spinal MRI procedure. The machine itself is a large, tube-like structure with a tunnel through which the images are obtained. Here’s what you can anticipate during the scan:
Loud Noises: MRI machines can produce loud knocking or banging noises as they generate images. You will be provided with ear protection, such as headphones or earplugs, to minimize the noise.
Stillness: To preserve the quality of the photos, it’s imperative to maintain as much stillness as possible throughout the scan. Any movement might cause the photos to become blurry, necessitating the need to repeat the process.
Communication: You will have a way to communicate with the MRI technologist throughout the procedure, usually through an intercom system. They will monitor you from a separate room and can provide reassurance or assistance if needed.
Duration: The needed imaging type and complexity determine the MRI scan’s length. While some scans may just take a few minutes, others might go on for an hour or longer.
Comfort Measures: If you experience discomfort or anxiety during the MRI, inform the technologist. They can make adjustments or provide support to help you feel more at ease.
The Importance of Early Detection
Early detection and diagnosis are crucial when it comes to spinal issues. Conditions like disc herniation, spinal stenosis, or tumors can worsen over time, potentially leading to more severe symptoms and complications. Spinal MRI provides a non-invasive and highly accurate means of identifying these problems, allowing for prompt intervention and appropriate treatment.
A Closer Look at Contrast-Enhanced MRI
MRI with contrast, although not always required, can provide invaluable information in certain situations:
Tumor Detection: Contrast-enhanced MRI makes tumors more conspicuous, aiding in accurate diagnosis and surgical planning.
Vascular Assessment: It helps visualize blood vessels within or around the spine, which is essential for evaluating vascular malformations or blood flow abnormalities.
Inflammation and Infections: Contrast can highlight areas of inflammation or infection, assisting in identifying the extent of the issue and guiding treatment.
It’s important to note that while contrast-enhanced MRI has its advantages, it may not be suitable for individuals with certain allergies or kidney conditions. Before selecting whether to employ contrast, your healthcare professional will carefully assess your medical history and unique needs.
