The left and right diaphragm are usually seen as clearly outlined domes. The right diaphragm should be higher than left due to the position of the liver. The peripheral margins of the diaphragm are called the costophrenic angles or sulci.

Free gas under the diaphragm indicates bowel perforation. Note that this sign is only likely to be seen if an erect film is taken.
