MRI clavical imaging is an advanced imaging procedure to assess the collarbone (clavical) and adjoining soft tissues, joints, and neuro-vascular structures. It can be especially helpful for conditions such as soft tissue injuries or minor bone changes that aren't well captured in X-rays or computed tomography (CT) scans.

The clavical provides structural support between the sternum and the scapula, plays an important role in shoulder stability, and is important for upper limb mobility. Shoulder pain resulting from injury or disease may hinder arm mobility and cause chronic pain. MRI provides high-resolution, multiplanar imaging that does not involve the use of radiation, and therefore is ideal for a full assessment.

Purpose of MRI clavical

1. Trauma Assessment

• Identifies fractures, bruises, and non-visible injuries (occult).
• Checks the associated soft tissue injuries after the alternative traumas to the shoulders or chest.

2. Joint Evaluation

• Evaluates the sternoclavicular and acromioclavicular joints for arthritis, dislocation, or ligament problems.

3. Soft Tissue Lesion Detection

• Recognises the injuries of muscles, tendinous or ligamental, around the clavical.

4. Tumour Evaluation

• Suspicious primary or metastatic bone tumours of the clavical.

5. Infection and Inflammation

• Identifies septic arthritis, inflammatory joint diseases, and osteomyelitis.

6. Chronic Pain Investigation

• Identifies the possible causes of chronic clavical pain that have not been identified on other imaging tests.

7. Post-Surgical Follow-Up

• Checks healing after clavical fracture fixation or joint reconstruction surgery.

Anatomy of the clavical and Related Structures

• The clavical is a bone that joins the manubrium (sternum) to the acromion process (scapula).
• The end of the inside makes the sternoclavicular joint with the sternum.
• The lateral end forms the acromioclavicular joint with the scapula.
• In addition to the pectoralis major muscle, there are surrounding muscles such as the deltoid, trapezius, subclavius and sternocleidomastoid.
• The costoclavicular, sternoclavicular and acromioclavicular ligaments are all significant supportive ligaments.
• Vascular and neurologic assessment is crucial in trauma-induced clavicular fracture, as the subclavian vessels and brachial plexus are located near the clavical.

Procedure for MRI clavical

Before the Scan

• Medical goals and history are discussed, including trauma, surgeries, or chronic pain.
• Metals (such as metallic objects and jewellery), and clothes with metal fasteners are removed.
• MR safe evaluation for patients with pacemakers or other incompatible devices is performed.
• Contrast administration can be scheduled for tumour or infection diagnosis or after surgery.

During the Scan

• The patient is in the "rest" position to reduce any movement as much as possible.
• To get a better image, a surface coil or a special shoulder coil is used.
• Pictures are taken from 3 positions – coronal, sagittal and axial – to see the clavical and other structures around it.
• If necessary, additional muscles, vessels or lymph nodes close to the scan site may be included.
• Typically, this takes about 25-40 minutes.

After the Scan

• Unless sedation has been used, patients will be able to carry out normal activities.

• The pictures are reviewed by a radiologist who writes a detailed report.

MRI Sequences for clavical Evaluation

T1-Weighted Sequences

• Offer a detailed evaluation of bone marrow and anatomy.

T2-Weighted Sequences

• Emphasise the collection of fluid, edema and soft tissue abnormalities.

STIR or Fat-Suppressed Sequences

• Improve diagnosis of bone marrow oedema, inflammatory lesions, and soft tissue lesions.

Gradient Echo Sequences

• Useful for identifying small hemorrhages or cartilage abnormalities.

Post-Contrast T1-Weighted Images

• Used for evaluating tumours, infections, and postoperative enhancement patterns.

Common Conditions Detected

Fractures

• Complete, incomplete, or stress fractures
• Detection of fracture lines not visible on X-rays

Bone Bruises

• Microtrabecular injuries following trauma

Joint Dislocations

• Sternoclavicular or acromioclavicular joint displacement

Ligament Tears

• Injuries involving the acromioclavicular, coracoclavicular, and sternoclavicular ligaments

Osteoarthritis

• Degeneration of the sternoclavicular or acromioclavicular joints with osteophyte formation

Inflammatory Arthritis

• Rheumatoid arthritis with erosions and synovitis

Osteomyelitis

• Bone marrow infection associated with soft tissue swelling

Bone Tumors

• All the primary tumours, like osteosarcoma and Ewing sarcoma
• Secondary lesions such as those developing from breast, lung or thyroid gland cancer.

Soft Tissue Masses

• A lipoma is a lump of fat, or a sarcoma or enlarged lymph nodes in the area around the collar bone.

Advantages of MRI clavical

• Better soft tissue, bone marrow and cartilage visualisation than that provided by X-rays and CT scans.
• Exposure to any type of ionising radiation did not occur.
• Multislice is an imaging capability that gives a more comprehensive evaluation by enabling multiplanar images.
• Offers early detection and detection of subtle bone and soft tissue abnormalities

Limitations

• Expensive and not as available as X-rays or CT scans
• Not recommended in individuals with some metallic implants.
• Vulnerable to movement artefacts, the patient is cooperative.
• Less useful for assessing fine details of the cortex than computed tomography (CT)

When This Scan is Preferred

• There has been no resolution of the pain from your clavical, despite having normal X-rays.
• Occult fracture/bone bruise (suspected)
• Assessment of tumours or infections of the clavical
• Planning for clavical reconstruction before surgery.Pre-operative planning for clavical reconstruction.
• Comprehensive assessment of hardware positioning and healing after surgery. 

Patient Preparation Tips

• Wear comfortable, metal-free clothing.
• Inform the radiology team about implants, injuries, allergies, or prior surgeries.
• Follow fasting instructions if contrast material is required.
• Remain still during the scan for optimal image quality.

Conclusion

MRI clavical is a state-of-the-art imaging technique that allows detailed assessment of the clavical and surrounding structures, such as other neurovascular structures, muscles, and joints. It is particularly useful to identify the location of the soft tissue injury, any deformity of the bone marrow and any imperceptible fractures under traditional imaging.

The scan becomes a highly valuable diagnostic tool and treatment planning and follow-up instrument in scenarios of trauma, degenerative disorders, infections, tumours or chronic clavical pain. With no known radiation exposure, MRI clavical remains a useful imaging modality in musculoskeletal and sports medicine diagnosis that offers great resolution and multi-planar imaging.
