Ankle MRI Scan Singapore: Procedure, Costs, & What to Expect

Your ankle has been hurting for weeks. The X-ray came back clear, yet walking still feels off. And now your doctor has booked you in for an MRI scan. So what are they hoping to find that the X-ray didn't show? 

The answer is 'quite a lot’.

X-rays are excellent for fractures and bone alignment, but they provide limited detail of ligaments, tendons, cartilage, and other soft tissues. An MRI can image all of these in detail, which is why it is often the scan of choice when ankle pain is unexplained. Understanding what the scan involves, what it costs in Singapore, and how to read your results can help you feel more prepared for what comes next.

What is an ankle MRI scan?

An ankle magnetic resonance imaging (MRI) scan is an imaging test that produces detailed pictures of the structures inside your ankle. It uses magnets and radio waves to capture your bones, ligaments, tendons, cartilage, and soft tissues.

An MRI scan does not use radiation, which makes it a safe option when your doctor needs a clearer picture of soft tissue injuries, such as ligaments and tendons, which often do not show up clearly on other imaging tests.

Why might your doctor recommend an ankle MRI?

Your doctor may recommend an ankle MRI when a standard X-ray or other tests have not fully explained your symptoms.

Common reasons include:

• Persistent ankle pain that has not improved with rest or treatment

• Ligament tears, such as injuries to the anterior talofibular ligament, one of the main stabilising ligaments on the outer side of your ankle

• Tendon injuries, including the Achilles tendon at the back of your heel or the peroneal tendons (the tendons that run along the outer side of your ankle)

• Cartilage damage to the joint surface

• Stress fractures (small cracks in the bone caused by repeated strain)

• Unexplained swelling or inflammation

• Suspected infection or growths

The detailed images from an MRI scan allow your doctor to understand the specific cause of your symptoms and plan the most appropriate treatment.

Whether it is a suspected ligament injury, tendon issue, or unexplained swelling, accurate diagnosis matters. Request an appointment with Thomson Medical to determine if an ankle MRI is the right next step.

How to prepare for your ankle MRI

Preparing for an ankle MRI is straightforward. A few simple steps beforehand can help things go smoothly on the scan day.

What to wear

Wearing the right clothing on the day helps the scan run more smoothly.

On the day of your scan:

• Choose loose, comfortable clothing that you can move around in easily

• Avoid anything with metal zippers, snaps, or underwire, as these can interfere with the scan

• Remove all jewellery, watches, hearing aids, and piercings before your appointment

• You may be asked to change into a hospital gown when you get there

Metal objects can disrupt the magnetic field used during the scan, so it is best to remove them before you go in. If you are unsure about anything you are wearing, you may ask the imaging team for advice.

Food, drink, and medications

Most ankle MRIs do not require fasting, so you can eat and drink as normal before your appointment. You can also continue taking your regular medications unless your doctor has told you otherwise.

Medical history and implants

Before you go in for your MRI, your care team will ask you a few questions about your health history.

Please let your care team know if any of the following apply to you:

• A pacemaker or implanted defibrillator (a device used to regulate or correct heart rhythm)

• Metal implants, screws, or plates anywhere in your body

• A cochlear implant (a device implanted in the ear to help with hearing)

• Metal fragments anywhere in your body

• Kidney disease

• Pregnancy or suspected pregnancy

Sharing this information helps your care team make sure the scan is right for you, or arrange a more suitable option if needed.

What happens during the scan?

Knowing what to expect during the scan can help the whole experience feel more manageable. The process is painless, and the team will be with you throughout.

Positioning and how long it takes

When you arrive, a radiographer will explain what to expect.

During your scan:

• You will lie on a padded table that slides gently into the MRI machine

• Your ankle will be placed in a specialised coil, a device that wraps around the area being scanned and helps produce sharper images

• The scan itself usually takes between 30 and 45 minutes

• Staying as still as possible during the scan helps the machine capture the clearest images

If you need a break at any point, let your team know. They can pause the scan and continue once you are comfortable again.

Noise and comfort

MRI machines are known for being noisy. You will hear loud tapping and thumping sounds throughout the scan, which is a normal part of how the machine works. To help with this, you will usually be given earplugs or headphones to reduce the noise.

Your care team will be able to hear you at all times. Let them know at any point if you feel uncomfortable.

Will you need contrast dye?

Not every ankle MRI includes contrast dye (gadolinium). This is a substance injected into your vein that makes certain areas show up more clearly on the scan, such as inflammation, infection, or subtle injury. 

Your doctor will let you know in advance if contrast dye is needed, along with any preparation steps you should follow.

How are your results interpreted?

Once the scan is complete, the images are reviewed by a radiologist, usually within a few days.

What the radiologist looks for

The radiologist examines your images in detail, looking at a range of structures and signs.

These include:

• Bone alignment and any signs of fractures

• Ligament tears or sprains

• Tendon inflammation or rupture

• Cartilage damage to the joint surface

• Fluid build-up around the joint

• Changes to the bone marrow, which can indicate stress reactions or early injury

• Any signs of infection or abnormal tissue growth

This detailed review will be sent to your referring doctor. The results are usually available within a few days of your scan. Your doctor will then go through the findings with you and recommend the next steps.

Is an ankle MRI safe?

MRI does not use ionising radiation, making it a safe and widely used imaging method. Most people go through the scan without any issues. However, there are specific circumstances where MRI requires extra care or may not be suitable.

Anxiety or claustrophobia

Feeling nervous about being in an enclosed space is more common than many people realise. If this is a concern for you, let your care team know before your scan.

They may suggest:

• An open MRI machine, which has a wider, less enclosed design

• A mild sedative to help you feel calm and relaxed during the scan

• Simple breathing or relaxation techniques you can use while you are inside the machine

These options are available to help make the scan feel as comfortable as possible for you.

Contrast dye reactions

Allergic reactions to contrast dye are uncommon, but they can occur, especially for those with kidney problems. If you have had a reaction to contrast dye in the past, it’s important to let the team know before your scan. 

They will take the appropriate steps to keep you safe and may discuss whether contrast is necessary in your case.

FAQ

Is an ankle MRI painful?

No, an ankle MRI is not painful. The scan itself is non-invasive, though you may feel mild discomfort from lying still for an extended period during the procedure.

How long does an ankle MRI take?

An ankle MRI typically takes 30 to 45 minutes, depending on the level of detail required and whether a contrast agent is used.

Can I walk after the scan?

Yes, you can usually walk and resume normal activities immediately after the scan, unless you have been given sedation.

Is MRI safe during pregnancy?

MRI does not use ionising radiation and may be performed during pregnancy when clinically necessary. Non-urgent scans are often deferred during the first trimester when possible. A contrast agent is usually avoided unless absolutely necessary, and your doctor will always weigh the benefits against any potential risks before proceeding.

Do I need a referral for an ankle MRI?

In Singapore, a doctor's referral is required for an ankle MRI. This helps ensure the scan is clinically appropriate for your condition and may be needed for insurance coverage and scheduling.

Can MRI detect all ankle injuries?

How accurate is an ankle MRI?

An ankle MRI is a well-established tool for detecting ligament tears, tendon injuries, cartilage damage, and stress fractures. However, accuracy can vary depending on image quality, the timing of the injury, and the expertise of the radiologist.
