CAMRT Radiography Practice Exam

What is the primary goal when positioning for knee projections?

1. Minimize radiation dose

2. Ensure maximum visualization of ligaments

3. Superimpose femoral condyles

4. Analyze joint effusion

The correct answer is: Superimpose femoral condyles

The primary goal when positioning for knee projections is to superimpose the femoral condyles. This positioning is crucial because it ensures that the radiographic image accurately represents the knee joint's anatomy, allowing for effective assessment of structures within the knee. Proper alignment of the femoral condyles during the imaging process helps to avoid distortion and provides a clear view of the joint space, which is essential for evaluating conditions such as osteoarthritis or fractures. While minimizing radiation dose, maximizing visualization of ligaments, and analyzing joint effusion are important considerations in radiographic practice, they serve more as secondary goals. The clear representation of the knee joint and its components through the superimposition of the femoral condyles is vital for a successful radiographic assessment. When the condyles are properly aligned, it leads to diagnostic images that guide clinicians in making informed decisions regarding patient care.
