Headache or Migraine? Signs You May Need an MRI

Headaches and migraines can disrupt daily life, making it essential to identify the root cause. While most headaches aren’t caused by serious conditions, your doctor may recommend an MRI if your symptoms indicate a potential underlying issue.

At BASS Medical Group, our neurologists and headache specialists offer comprehensive diagnostic services in Walnut Creek, San Francisco, Oakland, and throughout Northern California. If you suffer from chronic headaches or new, severe symptoms, an MRI may help rule out serious medical concerns.

What Is an MRI?

An MRI (Magnetic Resonance Imaging) scan uses magnetic fields and radio waves to create detailed images of your brain and nervous system. Unlike X-rays or CT scans, an MRI provides a clearer view of soft tissues, allowing doctors to detect structural issues that could be causing your headaches.

When Should You Consider an MRI for Headaches?

Your doctor may order an MRI if you experience any of the following:

• Frequent Headaches – Occurring daily or almost daily
• Sudden, Severe Headache – Often described as the worst headache of your life
• Headaches with Neurological Symptoms – Such as vision loss, confusion, dizziness, or numbness
• Changes in Headache Patterns – New onset headaches, especially if you’re over 50
• Headaches Triggered by Physical Activity – Occurring after exercise or exertion
• Headaches with Seizures or Loss of Consciousness
• Headaches Following a Head Injury – Especially with memory issues or personality changes

If you have a CT scan with inconclusive results, an MRI may provide a more detailed assessment.

What Can an MRI Detect?

An MRI is not used to directly diagnose migraines, but it can help rule out serious underlying conditions, including:

• Brain Tumors
• Stroke or Mini-Strokes (TIAs)
• Brain Infections (Abscesses, Meningitis, or Encephalitis)
• Hydrocephalus (Fluid Buildup in the Brain)
• Herniated Discs or Spinal Cord Issues
• Aneurysms or Blood Vessel Abnormalities

In some cases, MRI research has shown differences in brain structure in people with migraines, such as changes in the cortical thickness of pain-processing regions.

Is an MRI Necessary for Migraine Diagnosis?

Most migraine sufferers do not need an MRI unless they have unusual symptoms or signs of a secondary headache disorder. However, a doctor may recommend an MRI if a physical exam reveals neurological abnormalities, such as:

• Optic nerve swelling
• Double vision or vision loss
• Weakness on one side of the body
• Difficulty walking or unsteady gait
• Unusual reflexes or pupil response

If you experience persistent or worsening headaches, an MRI may provide peace of mind and help your doctor determine the best treatment plan.
