[Magnetic resonance imaging of the locomotor apparatus]

A multiplanar approach and a good tissue differentiation characterize magnetic resonance imaging which have a great role in exploring numerous musculo-skeletal lesions; review of main indications and limits. MRI is useful in diagnosing certain undisplaced fractures, fatigue and insufficiency fractures, and consequences. Fibrous cartilage and hyalin cartilage lesions, tears of tendons, ligaments and muscles are well appreciated. MRI is also very good for an early and correct diagnosis of avascular necrosis, spinal degenerative lesions, spinal consequences of rheumatoid arthritis and ankylosing spondylitis, and bone metastases. It is the technique of choice for local staging of bone and soft tissue sarcomas.
