What is the primary purpose of using a radiographic film marker?

The primary purpose of using a radiographic film marker is to identify the patient's side. These markers are crucial in differentiating between the left and right sides of the body, aiding in accurate diagnosis and supporting proper patient management. By marking the side of the patient, healthcare providers can avoid potential errors in interpreting images, especially in cases where anatomical structures may appear similar or when comparing images from different angles.

Using a marker is vital not just for documentation but also for ensuring that the radiologist or physician can accurately assess findings in the context of patient anatomy. This is especially important in situations like surgical planning or when monitoring the progression of conditions. Therefore, appropriate use of side markers helps maintain high standards of safety and precision in radiographic practices.
