MRI is a radiation-free test that can be used for knee disorders.
The principle of MRI is mainly through the resonance imaging of hydrogen ions in a magnetic field, and the resonance imaging technique is better for imaging soft tissues with high water content, such as tissue fluid, fat, cartilage, ligaments and so on. Most of the knee joint cavity and the surrounding area of the knee joint are soft tissue structures with high water content, so MRI can clearly visualize the above soft tissues.
MRI is used to determine the exact extent of damage to the soft tissues and articular cartilage. Common injuries such as meniscus, anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, synovial folds, cartilage, etc., which cannot be clearly visualized by conventional tests such as X-ray and CT, can be clearly visualized on MRI.
When knee discomfort occurs, it is recommended to consult a doctor in time and choose the appropriate examination method under the guidance of a professional doctor.
