A neck MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to create detailed images of the neck’s soft tissues, bones, nerves, and blood vessels. It is a non-invasive, radiation-free diagnostic tool that can reveal structural and pathological details not visible through X-rays or CT scans.

Why is it Performed?

A neck MRI is recommended for diagnosing or evaluating:

1. Persistent neck pain not responsive to other treatments.
2. Neurological symptoms like numbness, tingling, or weakness in the arms or legs.
3. Conditions such as:
   • Herniated or bulging discs.
   • Spinal stenosis (narrowing of the spinal canal).
   • Tumours or cancer affecting the spine or nearby structures.
   • Multiple sclerosis or other nerve-related issues.
   • Birth defects, arthritis, infections, or injuries in the cervical spine​.

It may also be used as pre-surgical imaging to guide treatment plans.

What are the benefits?

• Detailed Imaging: Provides high-resolution images of soft tissues (muscles, ligaments, and nerves) that are not visible in X-rays.
• Non-Invasive and Safe: No exposure to ionizing radiation.
• Early Detection: Identifies abnormalities like tumours, infections, or degenerative diseases at early stages.
• Tailored Treatment: Helps healthcare providers devise precise and effective treatment plans​.

What are the limitations?

• Claustrophobia: The enclosed nature of MRI machines can make the procedure uncomfortable for some patients, although open MRI options exist.
• Artefacts in Images: Motion during the scan can blur results, requiring the patient to remain completely still.
• Metal Interference: Metallic implants or fragments can distort images and pose safety risks.
• Time-Consuming: Scans can take 30–60 minutes or longer, which may be difficult for some patients.
• Cost: MRI scans are typically more expensive than other imaging methods like CT scans.
• Contrast Risks: Rare allergic reactions to gadolinium-based contrast agents may occur, particularly in patients with kidney issues.
