For example, anesthetics and/or steroids injected into an arthritic joint can help reduce the pain of osteoarthritis. In addition to helping diagnose osteoarthritis, radiographic technologies can also be used to guide your doctor while applying treatments. Ultrasound is excellent for evaluating the ligaments and tendons around the joint, which can be stretched or torn because of osteoarthritis.

Ultrasound is extremely sensitive for identifying synovial cysts that sometimes form in people with osteoarthritis.

CT examinations are also useful in providing guidance for therapeutic and diagnostic procedures.ĬT scan of an arthritic showing hip bony femoral head debris

CT (computed tomography) examinations, also called CT scans, are excellent for showing osteophytes (bone spurs) and the ways they affect adjacent soft tissues.

MRI of the hips showing osteoarthritis and edema of the femoral head and acetabulum. This in turn can postpone or eliminate the need for surgery. When evidence of cartilage wear is detected early, treatment can begin to prevent or delay progression. HSS uses a protocol of specific MRI pulse sequences to identify early evidence of cartilage degeneration. An MRI can show a reactive bone edema (fluid build-up in the bone marrow, which causes swelling), inflammation of soft tissues, as well as degenerated cartilage or bone fragments lodged in the joint.

MRI (magnetic resonance imaging) is very sensitive imaging that can reveal subtle changes in bony and soft tissues.

For this reason, radiologists at Hospital for Special Surgery often use the more sensitive MRI, CT and ultrasound forms of imaging, which are superior for detecting early osteoarthritis. Symptoms of osteoarthritis may arise before the damage can be seen in standard X-rays. Specialized Diagnostic Imaging Examinations These specialized views are designed to increase the sensitivity of the conventional radiographic study. In order to detect early cartilage wear, HSS uses special X-ray views in place of or in addition to these standard views.

An anteroposterior (AP) view (front-to-back view).

There are basic routine X-ray views for imaging each joint: The joint surfaces become misaligned and osteophytes (bone spurs) may form.

The body also responds with sclerosis (increased bone density), in which more bone grows in where the cartilage used to be. This can cause to cysts or fluid-filled cavities can form in the bone, which will also be visible in an X-ray. When cartilage is lost, bone rubs against bone. Note the narrower spacing on the right side of the image, where cartilage has degenerated. Specifically, an X-ray of a joint with osteoarthritis will show a narrowing of the space between the bones of the joint where the cartilage has worn away, as shown in the image below.Īnteroposterior (front to back) X-ray image of the knee showing osteoarthritis.

Regardless of the joint that is affected, osteoarthritis is revealed on conventional radiographs ( X-rays) by characteristics that are distinct from other joint disorders, such as rheumatoid arthritis. Types of Imaging Examinations for Osteoarthritis Conventional Radiographs – Routine X-ray Examinations Surgical options include osteotomies or joint replacement.Nonsurgical treatments can include physical therapy, modifications to physical activity, oral medications and/or intra-articular steroid injections.Treatments include conservative, nonsurgical therapy or surgery. The doctor who orders the imaging will use the description and gradation of osteoarthritis ("localized or diffuse" and "mild, moderate or severe," etc.) to determine treatment options. The findings from radiographic imaging depend on the stage of a person's OA. Articular cartilage degeneration is a gradual process. Degeneration of articular cartilage, leading to osteoarthritis, can occur naturally over time with a age or as a secondary condition to an associated injury, such as a trauma or repetitive-stress or occupational injury. The joints most frequently affected are the hip, knee, shoulder, the big toe and the base of the thumb. Osteoarthritis (OA) is one of the most common disorders of joints.
