CAMRT Radiography Practice Exam

What is the primary purpose of Arthrography?

1. A method for assessing bone density

2. A type of imaging test used to analyze a joint

3. An examination for cardiac function

4. A procedure for viewing soft tissues

The correct answer is: A type of imaging test used to analyze a joint

The primary purpose of arthrography is to analyze joints, specifically to obtain detailed images that can help in diagnosing various joint-related conditions. This imaging technique involves the injection of a contrast agent into the joint space, which enhances the visibility of the internal structures of the joint during imaging studies such as X-rays, MRI, or CT scans. By using arthrography, healthcare providers can identify issues like tears in ligaments, cartilage damage, or other abnormalities that may not be visible in standard imaging techniques. This method is particularly useful for assessing conditions affecting the knee, shoulder, hip, and other joints, making it an essential tool in musculoskeletal imaging. The other options mentioned do not relate to the primary purpose of arthrography. For instance, assessing bone density is related to techniques such as dual-energy X-ray absorptiometry (DEXA), and examinations for cardiac function would involve tests like echocardiograms or stress tests. Viewing soft tissues pertains more to imaging modalities focusing on the body's internal organs and structures rather than specifically on joints.
