CAMRT Radiography Practice Exam

What is the purpose of arthrography?

1. To assess lung capacity

2. To examine the spine for deformities

3. To visualize joints using contrast agents

4. To evaluate blood flow in arteries

The correct answer is: To visualize joints using contrast agents

Arthrography is a diagnostic imaging technique specifically designed to visualize joints by using contrast agents. This procedure is particularly useful in assessing joint abnormalities and conditions such as tears in the ligaments, cartilage damage, or other pathologies affecting the joint structure. By injecting contrast material into the joint space, radiologists can obtain detailed images that highlight the anatomy and any potential issues. This is crucial for accurate diagnosis and effective treatment planning for joint-related problems. In contrast, assessing lung capacity is typically performed using pulmonary function tests, while examining the spine for deformities involves imaging techniques such as X-rays or MRI, and evaluating blood flow in arteries is done through angiography. Each of these techniques targets different areas and systems within the body, which emphasizes the specialized nature of arthrography in joint assessment.
