In imaging, what items are evaluated under alignment?

• A. Spinal curve, scoliosis, leg length inequality, alignment of joints
• B. Cardiac silhouette, mediastinum
• C. Lung volumes
• D. Soft tissue density

Answer: (A)

Alignment in imaging is about how the bones and joints line up with each other on radiographs. This includes the spine’s curvature and straightness, the presence of scoliosis, differences in leg length that can tilt the pelvis, and whether joints are properly aligned without dislocations or subluxations. Together, these elements describe the overall skeletal alignment seen on the image. The other options don’t address this concept. Cardiac silhouette and mediastinum pertain to heart and mediastinal anatomy, not how bones and joints line up. Lung volumes relate to inspiratory effort and air content, not alignment. Soft tissue density refers to the appearance of soft tissues, again not alignment of the skeletal framework.
