CT vs MRI: What’s the Difference and Which One Do You Need?

Medical scans can feel overwhelming, especially if you’ve been told you need one, but don’t know what it actually means. At Van Veijeren & Partners, we believe in patient-centered care, which includes understanding your scan before stepping into the room. Today, we're breaking down the difference between two commonly used imaging tests: the CT scan and the MRI.

What is a CT Scan?

CT (Computed Tomography) uses X-ray technology to create detailed cross-sectional images of the body.

Quick Facts:

• Typically takes just a few minutes

• Excellent for showing bones, chest, lungs, and organs

• Often used in emergency situations

• Can detect fractures, internal bleeding, tumours, and infections

  
  

What it feels like: You lie on a table that moves through a doughnut-shaped scanner. It's fast and painless.

What is an MRI?

MRI (Magnetic Resonance Imaging) uses strong magnets and radio waves to produce highly detailed images—especially of soft tissues.

Quick Facts:

• Can take 30–60 minutes depending on the scan

• Excellent for imaging the brain, spinal cord, joints, and soft tissue

• No radiation involved

• Often used to detect neurological conditions, ligament tears, or spinal issues

  
  

What it feels like: You lie in a tunnel-like machine and must stay still. You’ll hear loud tapping sounds, but don’t worry—it is completely painless.

So… Which One Do You Need?

Condition	Recommended Scan
Head injury	CT
Stroke or brain tumour	MRI
Suspected fracture	CT
Joint or ligament injury	MRI
