Knee pain is one of the most common complaints, especially within the active Colorado population. Injury to the knee can occur from trauma, accidents, and more. An MRI of the knee can check the extent of an injury after a sudden trauma, diagnose a ligament or meniscus tear and the degree of that tear, and evaluate a finding discovered by an X-ray.
MRI stands for magnetic resonance imaging. An MRI of the knee uses magnets and radio waves to produce detailed 3D images of the knee and joint space. These signals convert to images for radiologists to interpret and distinguish normal tissues from injured tissues.
Radiologists use regular X-rays to examine fractured bones caused by trauma. Yet for the components within the joints and between the bones, MRI can provide more detail. A knee MRI can detect:
Meniscus tear or injury
Tendon injury
Ligament tears
Soft tissue swelling
Hemarthrosis
Subtle injuries commonly occurring in the knee include meniscus, tendons, and ligament tears. The meniscus is the cushion between the knee bones, while ligaments are the fibrous bands that hold the joints together, and the tendons connect bones to muscles. These are all best evaluated by MRI. Furthermore, if the MRI results show a meniscus tear within the knee joint, the MRI will be helpful to your orthopedic surgeon. The MRI gives an orthopedic surgeon a more detailed map for future surgery.
Sometimes an MRI only shows swelling of these soft tissue structures, rather than a tear. Injuries such as simple sprains and fluid within the joint will usually resolve on their own. Sprains may take time to heal, and physical therapy may be beneficial. Fluid within the joint space can remain in the same area or diffuse within the surrounding soft tissues. If blood is present in the knee joint as a result of trauma, it is called hemarthrosis.
The Women’s Imaging Center performs all knee MRI scans at the Denver/Cherry Creek center.
A Knee MRI is often used to find the reason for a complaint or symptom such as pain. For Colorado's active population, knee complaints are common from trauma or other causes. To examine fractured bones caused by trauma, radiologists use regular X-rays. Yet, the components within the joints and between the bones need MRI to look further. Common subtle injuries to the knee are meniscus, tendons, and ligament tears which are all best evaluated by MRI. However, sometimes an MRI only shows swelling of these soft tissue structures and not a tear. Ask your doctor to see if an MRI is the right imaging exam for you.
During a knee MRI, the patient lies on a table that slides into a tunnel-like machine. The machine creates a strong magnetic field and radio waves to produce detailed images of the knee. The procedure is painless, but patients may need to hold still for an extended period of time.
Knee MRI is generally considered safe and non-invasive. However, patients who have metal implants or devices, such as pacemakers, may not be able to undergo an MRI. Patients may also experience claustrophobia or anxiety during the procedure, but this can usually be managed with medication or relaxation techniques.
