1. What Is Musculoskeletal MRI?
Musculoskeletal disorders are among the most common health problems in the general population. Diagnosing these conditions requires a combination of medical history, clinical examination, laboratory testing, and imaging studies.
Magnetic Resonance Imaging (MRI) is an advanced imaging technique that uses strong magnetic fields and radio waves to generate detailed images of internal body structures. Unlike CT scans, it does not use X-rays, so patients are not exposed to ionizing radiation. An MRI machine is large, and uses a giant magnet to generate high energy electromagnetic fields
When radiofrequency waves are transmitted into the body, through soft tissues and bones, then the returning signals from tissues are processed into high-resolution images. Abnormalities on these images are valuable in helping doctors diagnose and treat patients. Musculoskeletal MRI can visualize bones, cartilage, tendons, ligaments, muscles, and surrounding soft tissues with exceptional detail. It is also used for surgical planning, especially in post-traumatic cases.
2. Indications and Contraindications
Musculoskeletal MRI is indicated for the diagnosis and management of musculoskeletal disorders. Injury to bones, cartilage, synovial membrane, ligaments, and tendons can be visualized on an MRI scan. MSK MRI are indicated for conditions such as
- Osteomyelitis (bone infection)
- Degenerative joint diseases (e.g., osteoarthritis)
- Bone fractures
- Ligament tears
- Inflammation of soft tissues (bursitis, tendonitis)
- Congenital skeletal abnormalities
- Bone and bone marrow tumors (primary or metastatic)
- Traumatic injuries to bones or joints
Although MRI is a safe imaging method, certain conditions prevent its use:
- Presence of metallic implants or devices, such as pacemakers, defibrillators, artificial heart valves, bone plates, or surgical clips. These implants can be damaged when subjected to electromagnetic waves, and images will be distorted.
- Metallic fragments near vital organs (especially around the eyes or head).
- Severe claustrophobia, as the scan requires lying still in a confined space.
- Extreme obesity, where the patient’s body size exceeds scanner limits.
There are not many contraindications for an MRI scan. Patients should always inform medical staff about any implants or health concerns before the procedure to ensure safety and image quality.
3. Clinical Value of Musculoskeletal MRI
Musculoskeletal MRI is ubiquitously ordered in Vietnam and many other nations. MRI offers high diagnostic precision and has greatly improved the detection and treatment of musculoskeletal diseases.
In trauma cases, MRI can detect fractures (displaced or not displaced), dislocations, ligament tears, and bone marrow edema — often missed on X-rays or CT scans due to being surrounded by other soft tissues or the injury being too minor. Ligament tears are only detectable on a musculoskeletal MRI
For bone tumors, MRI provides detailed information on size, location, and the degree of infiltration, helping surgeons plan safer and more accurate procedures.
MRI effectively evaluates joint abnormalities, particularly in joints such as the hip, knee, and shoulder. For the hip, an MRI is valuable due to structural complexity of the joint diagnosis of osteoarthritis, avascular necrosis of the femoral head, and nerve compression can be made with an MRI scan. For the knee, an MRI scan is useful for identifying ligament, meniscus, tendon, and bursal injuries. For the shoulder, an MRI scan can assess rotator cuff tears, labral injuries, bursitis, and joint instability.
4. Advantages of Musculoskeletal MRI
Musculoskeletal MRI offers several key advantages over other imaging methods:
- Non-invasive and painless
- No exposure to ionizing radiation
- Provides comprehensive visualization of structural abnormalities, with the ability to reconstruct 3D images
- Detects early changes in cartilage and soft tissues at the microscopic level
- Minimizes missed diagnoses, identifying lesions as small as a few millimeters, thus enabling early intervention and improved treatment outcomes
