Brain MRI at Gateway Diagnostic Imaging

What is a Brain MRI?

A brain MRI (Magnetic Resonance Imaging) is a safe, non-invasive imaging test that uses powerful magnetic fields and radio waves to create detailed pictures for your brain and surrounding structures. Unlike CT scans, brain MRI provides exceptional soft tissue detail without using ionizing radiation, making it the most comprehensive imaging method available for evaluating brain health and diagnosing neurological conditions.

During your brain MRI scan, you’ll lie comfortably on a padded table that slides into the MRI machine. Your head will be positioned in a specialized head coil designed to capture the clearest possible images of your brain. The exam typically takes 30-60 minutes, depending on the specific sequences needed and whether contrast material is required.

Why Your Doctor Ordered a Brain MRI

Your physician may recommend a brain MRI to diagnose, evaluate, or monitor various neurological conditions affecting your brain. This advanced imaging technique can detect problems that may not be apparent through physical examination alone, providing your healthcare team with crucial information needed to develop the most effective treatment plan.

Brain MRI Can Detect:

Neurological Disorders:

  • Multiple sclerosis (MS) lesions
  • Stroke or mini-strokes (TIAs)
  • Brain aneurysms
  • Arteriovenous malformations (AVMs)
  • Seizure disorder causes

Brain Tumors and Masses:

  • Primary brain tumors
  • Metastatic cancer to the brain
  • Benign masses or cysts
  • Pituitary tumors
  • Acoustic neuromas

Traumatic Brain Injury:

  • Concussion evaluation
  • Brain bleeding or bruising
  • Diffuse axonal injury
  • Post-traumatic brain changes
  • Long-term effects of head trauma

Memory and Cognitive Issues:

  • Early signs of dementia or Alzheimer’s disease
  • Mild cognitive impairment
  • Brain changes affecting memory
  • Age-related brain volume changes
  • Metabolic brain disorders

Headache-Related Conditions:

  • Chronic migraine evaluation
  • Cluster headache causes
  • Secondary headache disorders
  • Intracranial pressure changes
  • Sinus-related headache issues

The Importance of Brain MRI

Unmatched Brain Tissue Detail

Brain MRI provides superior contrast resolution, allowing radiologists to distinguish between different types of brain tissue, detect subtle abnormalities, and identify conditions other imaging methods might miss. This detailed visualization is crucial for accurate neurological diagnosis.

Early Detection of Serious Conditions

Many brain conditions, including tumors, strokes, and degenerative diseases, are most treatable when detected early. Brain MRI can identify these problems in their earliest stages, often before symptoms become severe, providing the best opportunity for effective treatment.

Monitoring Disease Progression

For patients with known neurological conditions like multiple sclerosis, brain tumors, or dementia, regular brain MRI scans help track disease progression, monitor treatment effectiveness, and guide ongoing care decisions.

Surgical Planning and Treatment Guidance

When brain surgery is considered, MRI provides surgeons with detailed anatomical maps of the brain, helping them plan procedures safely and effectively while minimizing risk to healthy brain tissue.

Ruling Out Serious Causes

For patients with concerning symptoms like severe headaches, seizures, or cognitive changes, brain MRI can rule out serious underlying causes, providing peace of mind and directing care toward appropriate treatments.

Radiation-Free Imaging

Unlike CT scans, brain MRI uses no ionizing radiation, making it safe for repeated examinations when necessary. This is especially important for young patients or those requiring multiple follow-up scans over time.

Contrast-Enhanced Scans:

If your exam requires contrast material (gadolinium), you may need to:

  • Avoid eating for 2 hours before your appointment to reduce the risk of nausea
  • Stay well-hydrated before and after the scan
  • Bring recent kidney function test results if requested
  • Inform us of any previous contrast reactions

Safety Screening

Metal Implants and Devices:

Our team will carefully review your medical history for any implanted devices or metal objects, including:

  • Brain aneurysm clips or coils
  • Deep brain stimulators or vagus nerve stimulators
  • Shunts or drainage devices
  • Previous surgical clips or screws

Eye and Facial Metal:

  • Inform us of any metal in your eyes (welding, grinding injuries)
  • Permanent makeup or tattoos near the eyes
  • Dental implants, bridges, or braces
  • Previous eye surgeries with metal implants

Managing Anxiety and Claustrophobia

Pre-Scan Anxiety Management:

  • Practice relaxation techniques at home
  • Bring a support person to the appointment, they can wait in the waiting room

Comfort Measures During Your Scan:

  • We provide blankets and positioning aids for comfort
  • You will have a call button to communicate with our technologist
  • We can provide music or earplugs to reduce scanner noise
  • The scan can be paused if you need a break

Open MRI Options:

  • Ask about our open MRI scanner if claustrophobia is a concern
  • Open MRI may take longer but provides more space and comfort
  • Discuss with your doctor whether open MRI is appropriate for your condition

What to Expect During Your Brain MRI

Arrival and Preparation

When you arrive at Gateway Diagnostic Imaging, our experienced registration team will check you in and review your medical history and safety questionnaire. You will have the opportunity to ask questions and discuss any concerns with our staff.

Pre-Scan Consultation

Our MRI technologist will explain the exam, review safety information, and address any last-minute questions you may have. If you’re receiving contrast, we will start an IV line and ensure you’re comfortable with the process.

Positioning and Setup

You will lie on the padded MRI table, and we will position your head in the specialized head coil. We use foam padding and supports to ensure your head stays still and you remain comfortable throughout the scan. You will be given earplugs or headphones to reduce noise.

During the Scan

The MRI machine will make various sounds during different imaging sequences – clicking, knocking, and buzzing noises are completely normal. Each sequence lasts 2-8 minutes, and we will tell you how long each one will take. It is important to remain as still as possible during each sequence.

Contrast Administration

If your scan requires contrast, we will inject gadolinium through your IV line partway through the exam. You may feel a cool sensation or mild warmth, but most patients experience no discomfort from the contrast material.

Communication Throughout

You will be in constant communication with our technologist through an intercom system. We will check on you between sequences and can stop the scan if you need a break or experience any problems.

After Your Scan

You can resume all normal activities immediately after your brain MRI. If you receive contrast material, we will monitor you briefly before you leave. There are no restrictions on walking, driving, or other activities.
