CAMRT Radiography Practice Exam

Which contrast study involves examining joint functionality?

1. Myelogram

2. Arthrography

3. Fluoroscopy

4. CT Angiography

The correct answer is: Arthrography

Arthrography is the contrast study specifically designed to examine joint functionality. This imaging technique involves the injection of contrast material directly into a joint space, allowing for detailed visualization of the joint and its internal structures, such as cartilage, ligaments, and tendons. The use of fluoroscopy or other imaging modalities during arthrography helps to assess the dynamic motion of the joint, ensuring that clinicians can evaluate both the anatomy and the function effectively. Myelogram focuses on the spinal canal and nerve roots rather than joint functionality, making it unrelated to joint assessments. Fluoroscopy is a dynamic imaging technique used for real-time visualization but does not specifically target joint evaluation; it's more general-purpose and can be used for various types of examinations. CT Angiography is a study of blood vessels using a contrast agent to visualize the vascular system, which is not centered around joint examination. Thus, arthrography stands out as the appropriate choice for studying joint functionality.
