CAMRT Radiography Practice Exam

What is the purpose of including the greater trochanters in a scoliosis series?

1. To help measure the degree of spinal curvature

2. To visualize the hip joint for better clarity

3. To assess leg length discrepancies

4. To evaluate pelvic alignment

The correct answer is: To help measure the degree of spinal curvature

The purpose of including the greater trochanters in a scoliosis series is to help measure the degree of spinal curvature. The greater trochanter serves as an anatomical landmark that can be used to establish a baseline for measuring spinal alignment and curvature. By referencing the position of these bony prominences, radiologists and technologists can more accurately assess the degree of scoliosis and monitor changes over time. This is particularly important for evaluating the progression of the condition and guiding treatment decisions. While options related to visualizing the hip joint, assessing leg length discrepancies, and evaluating pelvic alignment are relevant to general radiographic practices, they do not specifically address the primary goal for including the greater trochanters in a scoliosis series, which is focused on evaluating spinal curvature.
