Radiation-free magnetic resonance evaluation of the shoulder joint, tendons, muscles and labrum. The gold standard for soft-tissue pathology.
Indication
- Suspected rotator cuff tear (supraspinatus, infraspinatus, subscapularis)
- Labral injury after recurrent shoulder dislocation (Bankart, SLAP lesions)
- Chronic shoulder pain unresponsive to treatment
- Confirming the diagnosis of frozen shoulder (adhesive capsulitis)
- Findings of subacromial impingement syndrome
- Suspected post-traumatic bone edema, cartilage injury or muscle tear
- Pre-operative planning and post-operative follow-up
Preparation
- No metal accessories, jewelry or watches
- Inform staff in advance about pacemakers, cochlear implants, brain aneurysm clips or other metallic implants
- If contrast-enhanced study is planned, bring a recent kidney function (creatinine) result
- If you have claustrophobia (fear of enclosed spaces), notify the physician beforehand
How it's performed
- The patient lies supine and a dedicated coil is placed over the shoulder
- The arm is positioned naturally at the side
- The patient must remain still for 20-30 minutes during the scan
- Loud knocking sounds are heard during operation; ear protection is provided
- If needed, gadolinium-based contrast is given intravenously
- Two-way audio communication with the technologist is maintained throughout
Post-procedure
- No special restriction is required after the scan; daily life can be resumed immediately
- If contrast was given, drinking plenty of water that day is recommended
- Images are reviewed and reported by a radiologist
- Results are sent to the requesting physician and a treatment plan is made
Risks
- MRI does not use ionizing radiation, so no related risk
- Allergic reactions to contrast material are rare but possible
- Patients with kidney failure require special evaluation regarding gadolinium
- Sedation may be needed for individuals with claustrophobia or who cannot lie still
- MRI cannot be performed when incompatible metallic implants are present
FAQ
Is shoulder MRI painful?
The scan itself is painless. Only when contrast is given may a brief sting be felt while the IV line is placed.
How long does the scan take?
A standard shoulder MRI takes about 20-30 minutes. Contrast-enhanced protocols may take a little longer.
Can I have an MRI if I have a tattoo?
Most modern tattoo inks are MRI-compatible, but a warm sensation may occur in the area. Inform the technologist about old or metallic-content tattoos.
Can I get the results the same day?
Images are usually ready the same day; the radiologist's report is typically delivered within 1-2 working days, depending on the institution's workflow.
