MRI Image for Degenerative Joint Disease

Degenerative joint disease is also known as osteoarthritis or osteoarthrosis. It happens when the cartilage in the body wears down over time, and is the most common type of arthritis.

  1. Studies/Tests

    • The usual method of diagnosing degenerative joint disease (DJD) is with x-rays. However, when a physician needs further detail, he or she may request an MRI of the joints(s) involved.

    Reasons for MRI

    • Reasons a doctor might order an MRI for degenerative joint disease include suspicion of avascular necrosis (when the bones aren't getting enough blood) or soft tissue injury, which cannot be seen on x-rays.

    3-D Imaging

    • An x-ray can show how much damage exists in the bone and/or cartilage of the affected joint. An MRI goes even further, providing three-dimensional images.

    Drawbacks

    • MRIs are much more expensive than x-rays. As of 2008, the cost for an x-ray averaged under $150. An MRI could cost approximately $2,500.

    Dissenting Opinions

    • In March, 2008, the American Academy of Osteopathic Surgeons (AAOS) released a study that said they believe MRIs are being overused as diagnostic tools. The study concluded that doctors should rely on other means to diagnose degenerative joint disease/osteoarthritis, including researching the patient's medical history, physical examination, and obtaining x-rays.
