Quizplus · Accepted Answer

In order to demonstrate intraperitoneal air in an AP abdomen projection, the patient should be positioned upright for 5 to 20 minutes before obtaining the exposure. This allows the air to rise and accumulate under the diaphragm, making it more visible on the x-ray. It is not necessary to include the left iliac wing or take the image after a full inspiration. The lateral decubitus position may also be used to demonstrate intraperitoneal air, but this was not specified in the question.
