Key facts
Musculoskeletal MRI at a glance.
The six things worth knowing before you scroll further — definition, radiation, field strength, MR arthrogram, resolution and who reports it.
- 01
Definition
MRI of muscle, tendon, ligament, cartilage and bone marrow — the gold-standard soft-tissue and joint imaging test.
- 02
Radiation-free
MRI uses a strong magnetic field and radio waves — no ionising radiation, safe to repeat.
- 03
1.5T or 3T
1.5T is the workhorse for most joints; 3T offers higher resolution for cartilage, small ligaments and nerves.
- 04
MR arthrogram
Intra-articular gadolinium contrast for labral tears (shoulder, hip) and subtle cartilage lesions.
- 05
Sub-millimetre resolution
Modern MSK protocols routinely resolve structures below 1 mm — the level of detail arthroscopy demands.
- 06
Consultant MSK radiologist
Every report is issued by a consultant musculoskeletal radiologist — never a trainee alone.
Preparation and pathway
From consultation to report — what happens, in order.
One consultant MSK radiologist from protocol to structured report — usually within a week.
Phase 1 · Before your scan
Consultation and safety check
Phase 2 · On the day
Gown, coil, acquisition
Phase 3 · After
Report and follow-up
- 01
Before
MSK / orthopaedic consultation
A consultant reviews the injury, examination findings and any prior imaging, and confirms whether an MRI is the right step.
- 02
Before
Metal safety check
Screening for pacemakers, cochlear implants, aneurysm clips, shrapnel and other MRI-incompatible metalwork.
- 03
On the day
Change into gown
Metal-free gown, and a private changing cubicle. Jewellery, watches and cards left in a locker.
- 04
On the day
Position in scanner (limb coil)
A dedicated joint coil is placed around the region being imaged — knee, shoulder, ankle or wrist — to maximise signal.
- 05
On the day
20–40 minute acquisition
A sequence of images is acquired. You hear knocking noises through headphones and stay still, but the scan is painless.
- 06
On the day
IV gadolinium if arthrogram
For MR arthrogram, dilute gadolinium is injected into the joint before scanning — done under ultrasound or fluoroscopy guidance.
- 07
After
Radiologist report
A structured written report from a consultant MSK radiologist with images and clear next steps — usually within 48 hours.
Typical end-to-end: 3–7 days. Urgent cases: same day.
What it shows
What musculoskeletal MRI can find.
The presentations MSK MRI is designed for — with the red-flag sarcoma pathway called out separately.
-
Meniscal tear
The commonest knee-MRI finding — bucket-handle, radial and horizontal tears characterised and graded.
-
ACL / PCL rupture
Complete and partial cruciate ligament tears, with associated bone bruise pattern.
-
Rotator cuff tear
Supraspinatus, infraspinatus and subscapularis tears — full- or partial-thickness — with retraction measured.
-
Labral tear (shoulder, hip)
SLAP, Bankart and acetabular labral tears — often best characterised on MR arthrogram.
-
Cartilage lesion
Focal chondral defects and osteochondral injuries graded on high-resolution cartilage sequences.
-
Stress fracture
Occult stress fractures identified before they appear on plain X-ray — critical in athletes.
-
Bone marrow oedema
A sensitive marker of injury, inflammation, avascular necrosis and early inflammatory arthropathy.
-
Red flag: suspected bone / soft-tissue tumour — MDT sarcoma pathway
Any suspected primary bone or soft-tissue sarcoma is referred immediately to a specialist sarcoma MDT.
Next steps
What happens after the MRI.
The eight most common next steps — from physio and bracing to injection, arthroscopic repair, joint replacement and the sarcoma MDT pathway.
-
Physiotherapy
Structured rehabilitation is first-line for most tendon, ligament and cartilage injuries.
-
Bracing
Functional bracing for ligament injuries and post-operative protection.
-
Steroid or PRP injection
Image-guided corticosteroid or platelet-rich plasma injection for tendinopathy and joint inflammation.
-
Arthroscopic repair
Keyhole surgery for meniscal, labral, rotator cuff and cartilage lesions.
-
Joint replacement
Partial or total arthroplasty for end-stage joint disease.
-
Sarcoma MDT
Immediate onward referral to a specialist sarcoma multidisciplinary team when a tumour is suspected.
-
Chemoradiotherapy
Neoadjuvant or adjuvant systemic therapy and radiotherapy for confirmed malignancy.
-
Structured MSK follow-up
Serial clinical review and imaging to monitor progress and adjust the treatment plan.
Red flags
When MSK MRI shouldn’t wait.
The nine situations that push MSK MRI up the queue — and, in some cases, straight onto an emergency or sarcoma pathway.
-
Suspected sarcoma
A mass with concerning features — deep, growing, or larger than 5 cm — triggers immediate sarcoma-MDT referral.
-
Pathological fracture
A fracture through abnormal bone — suggests underlying tumour, metastasis or metabolic disease.
-
Cauda equina symptoms
Saddle anaesthesia, urinary retention or bilateral leg weakness — a surgical emergency requiring same-day MRI.
-
Progressive neurological deficit
Worsening weakness, numbness or reflex loss — expedited imaging and neurosurgical or spinal opinion.
-
Osteomyelitis
Bone infection — MRI is the most sensitive test, and antibiotics must not be started before biopsy where possible.
-
Septic arthritis
A hot, swollen joint with fever — a surgical emergency; joint aspiration precedes any imaging delay.
-
Discitis
Infection of the intervertebral disc — MRI with contrast is diagnostic and dictates antibiotic duration.
-
Complex regional pain syndrome
Disproportionate pain, swelling and skin changes — MRI supports diagnosis and rules out mimics.
-
Post-op infection
Increasing pain, swelling or discharge after surgery — urgent MRI to exclude collection or osteomyelitis.
Reading your report
An MSK MRI report can look intimidating. It isn’t.
Whatever the finding, the report keeps to the same four parts.
A quiet reminder
The report is written for your doctor, not for you — and that’s normal.
If you would like us to talk you through it before your follow-up, just ask.
- 01 Header
Indication and clinical context
Your details, the reason for the scan, the joint or region imaged and any prior surgery or imaging.
- 02 Technique
Field strength, coil and sequences
1.5T or 3T, which coil was used, which sequences were run, and whether intra-articular or IV gadolinium was given.
- 03 Findings
Structure-by-structure description
Bone, cartilage, ligaments, tendons, menisci or labrum, muscles and neurovascular bundle — each described in turn.
- 04 Impression
The conclusion — read this first
The diagnosis, grade or severity, and the concrete next step — physio, injection, arthroscopy or MDT.

Frequently asked
Everything we get asked about MSK MRI.
Quick answers on field strength, MR arthrogram, referrals, scan duration and safety.
-
What is a musculoskeletal MRI?
A magnetic resonance imaging scan of muscle, tendon, ligament, cartilage, bone marrow and joints. It is the gold-standard test for sports injuries, joint pain, tumours, inflammatory arthropathies and post-operative assessment — with no ionising radiation.
-
What is the difference between 1.5T and 3T?
1.5T is the workhorse for most joints and answers the great majority of MSK questions. 3T offers higher signal and finer resolution for cartilage, small ligaments and peripheral nerves — the trade-off is more artefact around metalwork and a slightly noisier scan.
-
When do I need an MR arthrogram?
When the question is a labral tear (shoulder or hip) or subtle cartilage lesion. Dilute gadolinium contrast is injected into the joint under ultrasound or fluoroscopy guidance before the MRI, which distends the joint and outlines the internal structures beautifully.
-
Do I need a referral?
Most clinics accept self-referral for a musculoskeletal MRI. We can arrange a fast-track private GP or MSK consultant if a formal referral is needed for insurance or an onward surgical pathway.
-
How long does the scan take?
Typically 20–40 minutes depending on the joint and whether contrast is used. You lie still on a table that slides into the scanner, and a dedicated joint coil is placed around the region being imaged.
-
Is a musculoskeletal MRI safe?
MRI is radiation-free and safe to repeat. The main safety consideration is metalwork — we screen for pacemakers, cochlear implants, aneurysm clips and shrapnel before you enter the room. Gadolinium contrast is very safe in patients with normal kidney function.

In practice, in London
What musculoskeletal MRI looks like on the ground in London
With musculoskeletal MRI, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. The NHS route for musculoskeletal MRI is thorough, but the queue is real. Most patients we speak with have been told to expect anywhere from a handful of weeks to several months, depending on their local trust and how the referral is graded. Going private in London usually collapses that window to a matter of days — often the same week if the diary allows. It isn’t about jumping a queue so much as buying time back while you still have the flexibility to plan around it.
The mechanics are straightforward: a consultant appointment, any tests done at a nearby CQC-registered site, and a written report back within a few days. London’s density of private diagnostics — Marylebone, the City, Chelsea, Canary Wharf — means most patients can find something that fits around work without a cross-town trek. For musculoskeletal MRI specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
We’re careful about what a private pathway for musculoskeletal MRI can and can’t promise. It can compress a wait, put you in front of a subspecialist quickly, and get a proper report in your hands within a week. It can’t rewrite what the imaging or the bloods say. Setting that expectation up front tends to make the whole experience less stressful.
