Length of exam varies by study.

Radiography, also known as x-ray, is the fastest and easiest way for a health care provider to diagnose broken bones. It can also be used to evaluate some diseases of the lungs, heart, and abdomen. It is the oldest and most frequently used form of medical imaging. Radiography involves exposing a part of the body to a small dose of radiation to produce an image of the internal organs. When x-rays penetrate the body, they are absorbed in varying amounts by different parts of the anatomy, creating an image on x-ray film.

Preparation:
There is no special preparation required for most x-rays. Women should always inform their doctor or x-ray technologist if there is any possibility that they are pregnant.
