MRI Scan FAQs: Risks, Side Effects, Preparation & Results Explained

MRI, or Magnetic Resonance Imaging, is a modern medical imaging method that uses strong magnets and radio waves to create detailed pictures of the inside of the body. Unlike X-rays or CT scans, it does not use radiation, making it a safer choice for many patients.

If you are preparing for an MRI, you might have questions about its risks, side effects, preparation, and results. This guide answers the most common questions in simple terms so you can feel confident and informed before your scan.

What Is an MRI Scan Used For?

MRI scans are used by doctors to see inside the body in great detail. They can show soft tissues, organs, blood vessels, and even nerves, which other scans might not capture clearly.

Common conditions MRI can detect include:

• Brain injuries, tumors, or multiple sclerosis
  
  
• Spinal cord problems such as slipped discs
  
  
• Torn ligaments and muscle injuries
  
  
• Internal organ issues affecting the heart, liver, kidneys, or pancreas
  
  
• Certain types of cancers at early stages
  
  

When doctors recommend an MRI:

• When X-rays or ultrasounds do not give enough detail
  
  
• To confirm a diagnosis before surgery
  
  
• To monitor treatment progress
  
  
• To investigate unexplained symptoms like chronic headaches or persistent pain
  
  

Can MRI Detect All Diseases or Nerve Damage?

While MRI is highly advanced, it has limitations. It cannot detect every type of disease, and some conditions require other tests.

Limitations of MRI:

• May not detect very small tumors or early-stage diseases in some areas
  
  
• Cannot always show calcium deposits as clearly as CT scans
  
  
• Not ideal for patients with certain metal implants
  
  

Nerve and soft tissue detection:
MRI is excellent for imaging nerves and soft tissues. It can help diagnose nerve compression, inflammation, or injury. This is why doctors often choose MRI for spinal and neurological problems.

When MRI is preferred over CT:

• When imaging soft tissues, brain, spinal cord, or joints
  
  
• When avoiding radiation is important, such as for children or pregnant women
  
  

What Are the Side Effects and Risks of MRI?

MRI scans are generally safe for most people. However, some patients may experience temporary side effects.

Does MRI have side effects?
Most people feel completely fine after an MRI. Rarely, patients may experience mild dizziness, nausea, or a headache, especially if contrast dye is used.

Why do I feel dizzy or tired after an MRI?
This can happen due to lying still for a long time or from the noise and enclosed space. These feelings usually pass within minutes to hours.

Are there long-term effects?
There are no proven long-term side effects of MRI without contrast. If contrast dye is used, side effects are rare and usually short-lived.

How long do MRI side effects last?
Most mild effects disappear within a few hours. If you experience prolonged symptoms, contact your doctor.

What Happens If MRI Results Are Bad?

How results are interpreted:
A radiologist reviews the MRI images and writes a detailed report. This report is sent to your doctor, who will explain the findings to you.

Follow-up actions and second opinions:
If the results show a serious condition, your doctor may suggest further tests, treatment, or surgery. You can always seek a second opinion to confirm the diagnosis and treatment plan.

How Long Does It Take to Get MRI Results?

Can results be seen immediately?
Technicians can view the images during the scan, but they do not interpret them. The official report comes from a radiologist.

Same-day vs delayed results:
Some clinics provide results on the same day, while others take one to three days.

Urgent cases:
If your case is urgent, many facilities can prepare reports within a few hours. Booking through Amax Healthcare can help you find centers that offer fast results.

Preparing for Your MRI Scan: What to Expect

Can I eat before an MRI?
For most MRIs, you can eat normally. If your scan requires contrast dye or sedation, you may be asked to avoid food for a few hours.

What to wear / Do you need to remove clothes?
Wear comfortable clothing without zippers or metal parts. Some facilities will provide a gown.

Can you wear a bra?
You can wear a bra if it has no metal underwire or clips. Otherwise, you may need to remove it.

Do I need to shave?
No, shaving is not required for an MRI.

Can I drink water before an MRI?
Yes, water is usually fine unless told otherwise.

Can you sleep or take a break during an MRI?
You can close your eyes and rest, but you must stay still. Breaks can be taken between sequences if needed.

Why is MRI so loud?
The machine makes knocking and tapping noises when taking images. Earplugs or headphones are usually provided.

After the MRI: What Should I Avoid?

Most people can return to normal activities right after an MRI.

Post-scan care:
Drink water if contrast dye was used, to help flush it out.

Activities to avoid:

• Heavy exercise immediately after sedation
  
  
• Driving if sedated during the scan
  
  

When to contact your doctor:
If you experience rash, swelling, or difficulty breathing after the scan, seek medical help immediately.

MRI vs CT Scan: What’s More Important or Expensive?

Key differences:

• MRI uses magnets and radio waves; CT uses X-rays
  
  
• MRI is better for soft tissues; CT is faster and better for bones
  
  

Cost comparison in Dubai:

• MRI: AED 800 to AED 6,000 depending on the type
  
  
• CT: AED 500 to AED 3,000
  
  

When doctors choose one over the other:
Doctors choose MRI when detailed soft tissue images are needed, and CT when speed or bone imaging is more important.

What Cancers Can MRI Detect?

MRI is effective in detecting and staging several types of cancer.

Most common cancers visible on MRI:

• Brain and spinal cord cancers
  
  
• Breast cancer
  
  
• Prostate cancer
  
  
• Liver cancer
  
  
• Ovarian and uterine cancers
  
  

MRI is also used to check if cancer has spread to other areas, which is important for planning treatment.

Common Symptoms That May Require an MRI

Doctors may recommend MRI for symptoms such as:

• Severe or frequent headaches
  
  
• Persistent joint pain or swelling
  
  
• Unexplained back pain
  
  
• Weakness, numbness, or tingling
  
  
• Unexplained weight loss or fatigue
  
  
• Screening after major accidents to check for internal injuries
