MRI Scan: Purpose, What to Expect, Price, Subsidy

What is an MRI scan?

An MRI scan is a non-invasive imaging technique that uses magnetic fields and radio waves to produce high-resolution images of your organs, tissues, and skeletal system. Unlike X-rays and CT scans, MRI does not use ionising radiation, making it a safer option for repeated imaging.

This article aims to provide you with comprehensive information about MRI scans, including their purpose, the procedure, pricing, and available subsidies in Singapore.

How does an MRI scan work?

MRI machines use a powerful magnet, radio waves, and a computer to create detailed cross-sectional images of your body. The machine aligns the protons in your body's water molecules and then uses radio waves to stimulate them.

What is an MRI scan used to diagnose?

Your doctor may recommend an MRI scan for various reasons and diagnostic purposes, including:

1. Brain and nervous system conditions

   • Detecting brain tumours

   • Diagnosing multiple sclerosis

   • Identifying causes of headaches

2. Musculoskeletal issues

   • Evaluating joint problems

   • Diagnosing spinal cord injuries

3. Cardiovascular conditions

   • Assessing heart structure and function

   • Detecting coronary artery disease

4. Cancer detection and monitoring

   • Identifying tumours in various parts of the body

   • Monitoring cancer progression and treatment effectiveness

5. Women's health

   • Evaluating pelvic pain

   • Detecting uterine fibroids or ovarian cysts

   • Identifying other gynaecological conditions

6. Other uses

   • Assessing liver and kidney function

   • Diagnosing conditions of the eyes and inner ear

What to expect during an MRI scan

1. Before the MRI scan

   • You'll be asked to remove metal objects, including jewellery and electronic devices.

   • You may need to change into a hospital gown.

   • If contrast material (an ingested dye used during imaging tests to help highlight abnormal areas inside the body) is required, a healthcare provider will insert an IV line.

2. During the MRI scan

   • You'll lie on a table that slides into the MRI machine.

   • The machine will make loud knocking and humming noises during the scan.

   • You'll need to remain very still to ensure clear images.

   • The scan typically takes 15 to 90 minutes, depending on the area being examined.

3. After the MRI scan

   • You can resume normal activities immediately after the scan if no sedation is used.

   • If you received contrast material, you'll be advised to drink plenty of water to help flush it out of your system.

Types of MRI scans

There are several types of MRI scans, including:

• Closed bore MRI: The standard type, offering the highest quality images

• Open MRI: More comfortable for claustrophobic patients but may produce lower-quality images

• Functional MRI (fMRI): Used to observe brain activity during specific tasks

MRI scan prices in Singapore

The cost of an MRI scan in Singapore can vary depending on the healthcare facility, the body part being scanned, the complexity of the scan and whether contrast material is used. Prices at different facilities typically range from S$1,000 to S$2,500 per scan.

Singaporean subsidies and financial assistance for MRI scans

For Singaporeans, MOH provides subsidies of up to 70% for patients at public specialist outpatient clinics. For Pioneer and Merdeka Generation senior citizens, additional subsidies of up to 50% and 25% are offered respectively. 

In addition to subsidies, patients can offset their remaining bill through their MediSave for up to $300 per year for outpatient diagnostic scans, including MRI scans. Seniors aged 60 years old and above can withdraw an additional $300 per year from MediSave for MRI scans under the Flexi-MediSave scheme.

To learn more about subsidies for MRI scans, please refer to Singapore’s MOH website. 

Preparing for your MRI scan

To ensure a smooth MRI experience:

• Inform your doctor of any medical conditions, allergies, or implants

• Follow any fasting instructions if required

• Wear comfortable, metal-free clothing

• Arrive early to complete the necessary paperwork

MRI scan risks and safety considerations

MRI scans are generally safe, but there are some considerations:

• People with certain metal implants or devices may not be able to undergo an MRI

• Pregnant women should consult their doctor before having an MRI

• There's a slight risk of allergic reaction to contrast material if used

Your MRI scan results

After your MRI scan, a radiologist will analyse the images and send a report to your doctor. Your doctor will then discuss the results with you and recommend any necessary follow-up actions or treatments.

MRI scans are a valuable diagnostic tool that can provide crucial information about your health. By understanding the process, costs, and available subsidies, you can be better prepared for your MRI experience. If you have any concerns or questions about your upcoming MRI scan, don't hesitate to discuss them with your healthcare provider.

An MRI scan typically takes 15 to 90 minutes, depending on the area being examined and the type of information needed.

Can I wear my glasses or hearing aid during the MRI?

You'll need to remove glasses, hearing aids, and any other metal objects before the MRI scan. These items can interfere with the magnetic field and affect image quality.

Can I eat before an MRI scan?

In most cases, you can eat normally before an MRI scan. However, some specific examinations may require you to fast for a few hours beforehand. Your healthcare provider will give you specific instructions.

Are MRI scans safe during pregnancy? 

While MRI scans don't use ionising radiation, they are generally avoided during pregnancy unless absolutely necessary. Always inform your doctor if you are pregnant or think you might be.

Can I undergo an MRI if I have metal implants or devices?

It depends on the type of implant or device. Some metal implants are MRI-safe, while others may pose a risk. Always inform your healthcare provider about any implants or devices you have.
