Private MRI Scan · Lower Limb
A private knee MRI scan produces detailed, radiation-free images of the knee joint, including the ligaments (ACL, PCL, MCL, LCL), menisci, articular cartilage, tendons and bone. It is the definitive investigation for knee pain, swelling, locking, instability and sports injuries.

About this scan
MRI (Magnetic Resonance Imaging) uses powerful magnetic fields and radio waves to produce detailed images of the body's internal structures, without any ionising radiation. It excels at imaging soft tissues: muscles, ligaments, tendons, cartilage, the brain, spinal cord, and abdominal organs. Unlike X-rays or CT, MRI can see subtle differences between different types of soft tissue, making it invaluable for diagnosing sports injuries, neurological conditions, and joint pathology.
A typical MRI scan takes 20–60 minutes depending on the area being scanned. You'll lie still inside a large, tunnel-shaped scanner while it takes thousands of cross-sectional images. A consultant radiologist then analyses these images and produces a written report, usually within 48 hours.
Key facts
The process
Complete a short MRI safety form to identify any contraindications such as metal implants or pacemakers.
The radiographer will position you on the scanner table. A coil (receiver) is placed around the area being scanned.
You'll move into the scanner and need to remain still while it operates. You'll hear loud knocking sounds; earplugs are provided.
A consultant radiologist analyses the images and sends your written report to your ScanBook patient portal within 48 hours.
Before your scan
Remove all metal items including jewellery, piercings, and hair clips before your appointment.
Inform the radiographer of any implants, pacemakers, cochlear implants, or metal surgical clips.
Most MRI scans require no fasting; you can eat and drink normally unless told otherwise.
Wear comfortable, loose-fitting clothing or a gown will be provided.
If you experience claustrophobia, contact us in advance; open MRI and sedation options are available.
FAQs
How long does a knee MRI take?
A knee MRI typically takes 25–40 minutes. You'll lie still on a table with your knee inside a dedicated knee coil. It is painless and does not involve any radiation.
Do I need a GP referral for a private knee MRI?
No. ScanBook does not require a GP referral. You can book directly and receive a consultant radiologist report without visiting your GP first.
Can a knee MRI show cartilage damage?
Yes. MRI is the most sensitive imaging tool for detecting articular cartilage damage, including early wear that may not be visible on X-ray.
Will the MRI show if I have an ACL tear?
Yes. MRI is the gold-standard investigation for ACL and other ligament injuries. It shows whether the ligament is intact, partially torn, or completely ruptured, and assesses associated meniscal and bone injury.
How long until I get my results?
Your consultant radiologist's written report is delivered to your ScanBook patient portal within 48 hours of your scan.
Do I need a GP referral?
No. ScanBook allows you to self-refer for most MRI scans. You can book directly online without seeing a GP first.
Is MRI safe?
Yes. MRI uses no ionising radiation; it relies on magnetic fields and radio waves, which are completely safe for most people. It cannot be used if you have certain metal implants (pacemaker, cochlear implants, some vascular clips).
What if I'm claustrophobic?
Tell us when booking. Many of our partner centres have wide-bore (70cm) scanners that feel less confined. Open MRI options are available at selected centres, and mild sedation can be arranged with your GP.
