Paleography is the method of roentgenologic examination of the walls of the hollow organs with the introduction of gas or air inside the body and in the environment, resulting in the walls of the body become clearly visible on the background gas.

Paleography (from lat. paries, parietis - a wall, and Greek. grapho - writing, picture) - a method of roentgenologic examination of the walls of the hollow body.
P. enables to assess the outward condition of the authority, to study the thickness of the walls, to identify the boundaries of the tumor and its length (especially when endophytic cancer), to clarify the relationship struck the wall with the surrounding organs.
If paleographie stomach into the abdominal cavity of the patient is injected 1000-1500 ml of oxygen, then a thin probe is under the control of the screen in the stomach enter 200-300 ml of air. Mnogoproektsionnoe study creates conditions for detecting the thickness of the wall of the various sections of the stomach (normal thickness of 3-5 mm).
To study the thickness of the wall of the esophagus (2-3 mm) examine inflated air esophagus in a diagnostic pneumomediastinum imposed parasternal way.
Paleographie colon carry out the introduction of 250-300 ml of air probe into the large intestine while simultaneously imposed diagnostic pneumoperitoneum.
P. bladder and uterus - see Uterus, bladder.
Contraindications are the same as when applying diagnostic pneumoperitoneum (see) and pneumomediastinum (see).
