CAMRT Radiography Practice Exam

Which of the following is a common reason for taking a lateral x-ray?

1. To assess lung capacity

2. To view spinal alignment

3. To check for fractures

4. To measure organ size

The correct answer is: To view spinal alignment

Taking a lateral x-ray is commonly used to view spinal alignment because this positioning allows the radiologist or healthcare provider to clearly visualize the curvature and alignment of the spine from a side perspective. The lateral view is particularly effective for assessing issues such as scoliosis, lordosis, and other spinal disorders by providing a comprehensive view of the vertebrae and intervertebral spaces. This projection can help identify any abnormalities, such as misalignments or degenerative changes in the spinal column, which may not be as evident in anteroposterior (AP) views. While lateral x-rays can provide some information regarding certain organ sizes or detect fractures, these uses are typically not as foundational or effective for the specific purpose of assessing spinal alignment as it is.
