Magnetic resonance imaging of the knee joint is an optimal method in the diagnosis and comprehensive assessment of the structural components of the knee. So, what subjects is magnetic resonance imaging of the knee ligament indicated for?

Magnetic resonance imaging (also known as MRI) of the knee joint uses a strong magnetic field, radio waves, and a computer to create detailed images of the structures in the knee joint such as cartilage, bone, tendons, ligaments, etc. muscles, blood vessels.
Generally, magnetic resonance imaging (MRI) of the knee is used to diagnose or evaluate pain, swelling, or bleeding in and around the joint. Can an MRI of the knee joint help determine if you need surgery?

The knee magnetic resonance imaging method is most commonly applied to subjects with rheumatoid arthritis, sedentary, sudden movement that causes joint pain, the elderly, people with osteoporosis, and sports athletes. , infants with joint abnormalities.
Specifically indicated for knee joint magnetic resonance imaging for:
Unusual cases or damage to cartilage and ligaments. The knee has abnormal signs such as: Weakness, difficulty in movement, pain, swelling... Inflammation or degeneration such as: Osteoarthritis, osteomyelitis, arthritis; Vigorous activities cause knee injuries such as: Torn or damaged ligaments, torn tendons...; Fractures are detected but CT, X-ray or other imaging methods are not found; Knee effusion; Knee joint difficult or limited movement;

Magnetic resonance imaging of the knee joint is an optimal method in diagnosing and comprehensively evaluating the structural components of the knee joint such as: bones, muscles, joints, ligaments, synovial fluid..., detecting the Abnormal point in tissue structure, muscle that other techniques such as CT scan, X-ray or ultrasound cannot perform.
The outstanding advantage of knee joint resonance imaging is that it is a non-invasive diagnostic technique that does not contain radioactive ions and causes no side effects. Today's modern magnetic resonance imaging machine overcomes most of the disadvantages of previous models such as emitting loud noise, long execution time and bringing the most comfortable feeling to the patient.
The time to take a knee MRI is quite fast, usually about 10-15 minutes, the results are available within 45 minutes.

To date, no side effects have been reported. However, before performing an MRI of the knee ligament, it is necessary to tell the doctor the medical history, especially the following cases:
The patient has had metal implant surgery such as: implanted human heart valve creating, placing coronary stents, clamping coronary arteries... Patients are afraid of tight, closed places, claustrophobia (Claustrophobia) Contains metal foreign bodies in the body such as shrapnel, surgical screws bones, dentures, braces, artificial bone crests... Using assistive devices: Pacemakers, defibrillators, hearing aids, automatic drug pumping devices under the skin (with controlled patients) diabetes)... Mental patients, oversized people, naughty, uncooperative children. The patient works directly in the metal mining and manufacturing environment.

Before taking magnetic resonance imaging of the knee joint:
Patients should bring old medical records, identification papers, recent test results... for the doctor to review and advise on implementation. Pregnant women under 12 weeks of age should carefully consider and have a specialist's appointment when performing magnetic resonance imaging of the knee ligament. Do not bring metal objects such as: tie clips, keys, ballpoint pens, coins, belts, jewelry, watches... because they can affect the patient's body and make mistakes. result deviation. Electromagnetic devices such as credit cards, automatic withdrawal cards (ATM cards), memory cards, magnetic keys, mobile phones may lose data when conducting magnetic resonance imaging. For patients who have undergone surgery to implant cardiovascular support devices, pacemakers, hearing aids, vascular clamps, bone screw braces, dentures, artificial bone caps... it is necessary to clearly state the information. consult your doctor. Mentally ill people, young children, people with claustrophobia may be prescribed sedation or anesthesia as prescribed by the doctor before the procedure.
