Sensitive most investigation to detect minimal intraperitoneal free air
Correct Answer: Chest x-ray
Description: Although as little as 1 ml of free gas can be demonstrated radiographically, either in chest PA or a left lateral decubitus abdominal film, CT is superior to plain radiographs in detecting minute quantities of pneumoperitoneum. Chest PA view is more sensitive than even a left lateral decubitus abdominal film.
