Routine X-rays, or radiographs, are images of the body performed using X-rays to expose a piece of film. The X-rays pass through different tissues of the body and onto the film in different amounts. For instance, very few X-rays pass through bones, so they appear white on the film; more pass through muscle, so they appear gray; etc. These differences are what create the image on the film. Many parts of the body such as chest and bones are imaged this way. Pneumonia, fractures and other diseases can be detected.

Preparation for the Exam

No preparation is needed for most exams.

During the Exam

In most cases, your child will be able to wear clothing. For some studies, your child may be asked to change into a gown or remove metal objects such as jewelry from the view of the X-rays.

A piece of film is placed next to a body part such as the chest or hand. One or more images are taken in different views. The film is then developed and brought to the radiologist for review.

Occasionally a film may need to be repeated because there was motion, or to further clarify the diagnosis. Exams typically take 15 minutes or less.
