When your doctor recommends medical imaging, you might wonder, “CT scan vs MRI – which is better for me?” While both technologies help doctors see inside the body without surgery, they are used for different purposes and offer different benefits. Learn more about their key differences, how each scan works, and what Singaporeans should consider when choosing between the two.
What Is a CT Scan?
A CT scan (Computed Tomography) uses X-rays to create detailed cross-sectional images of the body and is commonly used to detect bone fractures, internal bleeding, lung conditions, and tumours. It is fast and efficient, often completed within minutes, making it especially useful in emergencies.
What Is an MRI?
An MRI (Magnetic Resonance Imaging) uses strong magnetic fields and radio waves to produce highly detailed images of soft tissues, such as the brain, spinal cord, joints, and blood vessels. While it takes longer than a CT scan, it is preferred for diagnosing complex or soft tissue conditions without exposing patients to radiation.
CT Scan vs MRI: What Are the Main Differences?
| Feature | CT Scan | MRI |
| Technology | X-rays | Magnetic fields and radio waves |
| Best For | Bones, chest, abdomen, trauma | Brain, joints, spine, soft tissues |
| Radiation | Yes | No |
| Scan Time | 10 to 30 minutes | 30 minutes to 1 hour |
| Cost | S$600 to S$1,000 (before GST) | S$900 – S$4,000 |
Disclaimer: The costs indicated are estimates and may vary depending on the provider, type of scan, and other factors.
Safety and Suitability
- Radiation exposure: CT scans involve small amounts of radiation. While generally safe, repeated scans should be avoided unless necessary.
- Metal implants: Patients with pacemakers, cochlear implants, or metal fragments may not be suitable for MRI.
- Claustrophobia: MRI machines are enclosed, which may cause discomfort for some. CT scans are quicker and less confining.
Your doctor will evaluate your condition and medical history before recommending the most appropriate scan.
Which Is More Common in Singapore?
In Singapore, both CT scans and MRI scans are widely available at public hospitals, private medical centres, and specialist imaging clinics. The choice depends on the condition being investigated, urgency, and clinical need.
Waiting times and costs may vary between institutions.
