X-rays are the most common examination performed in radiology. By exposing a part of the body to a small dose of ionizing radiation, pictures of the inside of the body are produced. At least two images are taken, but additional images may be required depending on the body part being examined.
X-rays are a form of radiation that pass through most objects. The technologist carefully aims the X-ray unit at the part of the body being examined. A small burst of radiation passes through the body producing an image of that particular part of the body.
Preparing for an x-ray
There is no special preparation for an X-ray. An X-ray exam is offered on a walk-in basis, with no appointment necessary. A written order from your physician is required. If you are pregnant, you will need to notify the technologist prior to the exam.
Expectations during an x-ray
You may need to change into a gown upon arrival. You may also be asked to remove jewelry, eyeglasses and any metal objects that may interfere with the images. Special care is taken during any X-ray examination to use the lowest possible radiation dose while producing the best image for an evaluation.
Length of x-ray exam
Typically, these exams require 5 to 15 minutes to complete.
