When x-raying an AP lumbar spine, why are the knees bent?

To reduce lordotic curvature
To increase the lordotic curvature
To prevent motion during the exposure
To align the pelvis with the tabletop

The correct answer is: To reduce lordotic curvature

When x-raying an AP lumbar spine, bending the knees is primarily done to reduce lordotic curvature. In the natural position of the lumbar spine, there is a curvature known as lordosis, which can make it challenging to capture an accurate radiograph of the lumbar region. By bending the knees, the pelvis is tilted backward, which helps to flatten out this lordotic curve. This positioning allows for better visualization of the lumbar vertebrae by creating a more uniform spacing between them and reducing distortion. Proper technique in reducing the lordotic curvature is crucial for obtaining clear images that are necessary for an accurate diagnosis.
