CAMRT Radiography Practice Exam

What is the purpose of lateral bending for scoliosis imaging?

1. To assess lung function during breathing

2. To determine structural changes when bending

3. To evaluate muscle strength on both sides

4. To check for nerve damage

The correct answer is: To determine structural changes when bending

The purpose of lateral bending during scoliosis imaging is primarily to assess structural changes in the spine. When a patient bends laterally, this allows for the evaluation of how the spine and the surrounding structures respond to movement. In cases of scoliosis, the degree of curvature and its flexibility can be better understood through this kind of imaging technique. By observing the spinal alignment while the patient is in a bent position, radiologists and clinicians can determine if the scoliosis is structural, which is characterized by a fixed curve that does not change significantly with movement, or functional, which may change with positional adjustments. This information is crucial for deciding on appropriate treatment options and understanding the progression of the condition. Other options, such as assessing lung function, evaluating muscle strength, or checking for nerve damage, do not directly relate to the purpose of lateral bending in scoliosis imaging. These aspects may be relevant in a broader clinical evaluation but are not the primary focus during lateral bending assessments for scoliosis.
