Quick answer: A closed MRI uses a narrow tunnel and a stronger magnet, giving the sharpest images — but it can feel confining. An open MRI is open on the sides, far more comfortable for claustrophobic patients, larger body types, children and anxious patients, with image quality that is excellent for most everyday scans. At Al-Nasar Lab in Lahore you can choose either — a 1.5 Tesla closed MRI for the highest detail, or an Open MRI for maximum comfort.
What is a closed MRI?
A closed (or “traditional”) MRI is the tunnel-shaped scanner most people picture. You lie on a table that slides into a cylindrical magnet. Because the magnet fully surrounds you, it can use a higher field strength — such as 1.5 Tesla — which produces extremely detailed images, ideal for the brain, spine, small joints and complex cases.
What is an open MRI?
An open MRI is built with open sides rather than a closed tunnel, so you are not fully enclosed. It dramatically reduces the feeling of confinement, making it the preferred choice for patients who feel claustrophobic, larger patients, children, elderly patients, and anyone who feels anxious about scans. At Al-Nasar Lab, our Open MRI is designed for comfort while still delivering reliable, diagnostic-quality images.
Open MRI vs closed MRI: the key differences
| Feature | Open MRI | Closed MRI (1.5T) |
|---|---|---|
| Comfort / space | Open sides — best for claustrophobia & larger patients | Enclosed tunnel — can feel confining |
| Image detail | Excellent for most routine scans | Sharpest detail, best for complex cases |
| Best for | Claustrophobic, anxious, children, larger body types | Brain, spine, small joints, detailed studies |
| Noise | Generally quieter, more open feel | Louder, fully enclosed |
| Available at Al-Nasar | Yes | Yes (1.5 Tesla) |
Who should choose an open MRI?
- Anyone who feels claustrophobic or anxious in tight spaces
- Larger patients who may not fit comfortably in a closed tunnel
- Children and elderly patients who need a calmer experience
- Patients who simply want a more relaxed scan for routine imaging
When is a closed (1.5 Tesla) MRI better?
When your doctor needs the finest possible detail — for example, detailed brain imaging, the spinal cord, small joints, or complex diagnostic questions — a higher-field closed MRI is usually preferred. Our radiologists will guide you to the right machine based on your referral and your comfort.

Frequently Asked Questions
Is an open MRI as accurate as a closed MRI?
For the majority of routine scans, an open MRI gives excellent diagnostic images. For cases needing the very highest detail, a 1.5 Tesla closed MRI is preferred. Our radiologists recommend the best option for your specific scan.
Which MRI is best if I’m claustrophobic?
An open MRI is the best choice for claustrophobia because it is open on the sides and far less confining than a closed tunnel.
Does an open MRI take longer?
Scan times are broadly similar — most MRI scans take about 20–45 minutes depending on the body part being examined.
Can larger patients use the open MRI?
Yes. The open design comfortably accommodates larger body types that may not fit well in a closed tunnel.
