Quick answer: Yes — an MRI is very safe for most people. It uses powerful magnets and radio waves, not radiation, so it is even used in children and (when needed) in pregnancy. The main precautions are metal implants and pacemakers, which you must declare beforehand. At Al-Nasar Lab in Lahore, scans run on a 1.5 Tesla MRI and an Open MRI for anxious or claustrophobic patients.
Does an MRI use radiation?
No. Unlike X-rays and CT scans, an MRI uses a strong magnetic field and radio waves — there is no ionising radiation. This is one reason doctors often prefer MRI for repeated imaging and for soft-tissue problems.
Is an MRI safe during pregnancy?
MRI without contrast is generally considered safe in pregnancy when the scan is medically necessary, especially after the first trimester. Always tell your doctor and the technologist if you are or might be pregnant so they can choose the safest protocol.
Metal implants & pacemakers — the key precaution
Because of the strong magnet, you must inform staff if you have any of the following before your scan:
- Pacemaker or implanted defibrillator
- Cochlear (ear) implants
- Aneurysm clips or metallic surgical implants
- Metal fragments in the eye, or recent surgery
Many modern implants are “MRI-conditional” and still allow scanning — our team checks this for your safety.
What to expect during your MRI
- You lie still on a padded table that moves into the scanner
- The machine makes loud knocking sounds — earplugs or headphones are provided
- Most scans take about 20–45 minutes
- You can speak to the technologist at any time
What if I’m claustrophobic?
Tell us in advance. Al-Nasar Lab offers an Open MRI with open sides that is far more comfortable for claustrophobic patients, larger body types and children.
