Frequently Asked Questions About Chest X-Ray

Doctors can also use chest X-rays to see if any implanted materials are still in place. It is also used to ensure the patient is not experiencing any fluid buildup or air leaks.

How can one prepare for a chest X-ray?

Chest X-rays will require very minimal preparation. Prior to the procedure, patients will be asked to remove any body piercings, eyeglasses, jewelry, and other metals the individuals may be wearing.

Patients with any implanted device like pacemaker or heart valve should tell the individual performing the procedure. It is possible that you can still go through with the procedure even with metal implants. However, other scans like MRIs may be risky for those who have metal in their bodies.

How is a chest X-ray performed?

X-ray is carried out in a special room with a movable camera that is attached to a metal arm. You will be standing next to a “plate.” The plate contains a special sensor or an X-ray film that records the images taken on a computer. 

A front and side view of the chest will be taken. While the images are taken, you need to hold your breath so the chest remains completely still. Any movement while the images are taken might turn out blurry. 

As the radiation passes through the body, bones, muscles of the heart, and other dense materials will appear white. After the images have been captured successfully, the procedure is complete and you can change back into your clothes and go about your day. The whole process will only take around 20 minutes from start to finish. 

X-rays are not recommended for pregnant women as the radiation might cause harm to the unborn baby. If you suspect you are pregnant, it is recommended that you tell your doctor first before agreeing to a chest X-ray.
