A radiograph of an AP thoracic spine projection reveals that the upper thoracic spine is overexposed.The lower vertebrae have acceptable density and contrast.Which one of the following modifications will improve the visibility of the upper thoracic spine?

Question

Quizplus · Accepted Answer

Using a compensating (wedge) filter will improve the visibility of the upper thoracic spine by decreasing the amount of radiation reaching that area, therefore reducing overexposure. Placing the upper spine under the cathode side of the tube (option A) would increase the amount of radiation received and worsen the overexposure. Increasing kV (option C) would decrease contrast, but would not necessarily address the overexposure issue. Using a breathing technique (option D) is not applicable to this scenario.
