A Chest X-Ray projects an image of your chest onto a screen, generating a printed image on X-Ray film that a doctor or radiologist can read to assess your health. X-Rays are taken by radiologists — specialists in the imaging of human anatomy — who are also trained in other imaging technologies such as ultrasounds, MRIs, and CT scans. If a doctor suspects your condition involves the chest, a Chest X-Ray is usually one of the first tests they will order.
A Chest X-Ray can help detect a wide range of conditions affecting the chest area, including:
* Pneumonia: An infection that inflames the air sacs of the lungs, caused by a virus, bacteria, fungi, or other germs. A radiologist will look for white spots in the lungs (called infiltrates) that indicate infection.
* Tuberculosis: An infectious disease spread through airborne droplets. A Chest X-Ray can detect abnormalities that may indicate tuberculosis.
* Lung cancer: The uncontrolled growth of abnormal cells in one or both lungs. A radiologist will look for a white-grey mass on the X-Ray as an indicator.
* Breast cancer: A Chest X-Ray can help determine whether breast cancer has spread to the lungs.
* Enlarged heart: Usually indicative of a heart valve problem or heart disease. A Chest X-Ray will identify an enlarged heart, after which further tests can determine the cause.
* Blocked arteries: A Chest X-Ray can reveal changes in the size, shape, and position of major blood vessels and arteries that may indicate blockages.
* Rib cage injuries: Including broken ribs, fractures, internal bruising, and torn cartilage resulting from sudden accidents such as a fall or car crash.
* Congestive heart failure: A Chest X-Ray can show changes or problems in the lungs that stem from heart issues, which may indicate congestive heart failure.
Many serious — even life-threatening — conditions can be detected by something as straightforward as a Chest X-Ray. Early detection through imaging significantly improves the chances of successful treatment for a wide range of health problems.
A Chest X-Ray is a minimally invasive procedure requiring very little preparation. To receive a referral, you will first need to visit your doctor and discuss your symptoms. If the cause cannot be identified through the consultation alone, you will be referred to a chest radiography specialist.
Before the scan, you will be asked to change into a hospital gown and remove all metal objects — including jewellery, watches, body piercings, glasses, and hairpins. No metal objects can be near an X-Ray machine as they will interrupt the beam.
Once changed and with all metal removed, you will enter the X-Ray room. To capture the front image of your chest, you will be asked to stand with your chest against the metal plate of the X-Ray machine with your hands on your hips. The radiologist will then move to a connecting room to take the images.
You will then turn to the side so the technician can capture a lateral image — standing with your side against the metal plate and your arms raised.
It is important to remain very still throughout, as even breathing in and out can blur the image. Once the radiologist is satisfied with the images, you are free to leave. The process generally only takes a few minutes.
Radiologists are highly trained medical professionals who ensure your safety throughout the procedure. The amount of radiation emitted during a standard Chest X-Ray is very small — equivalent to what an average person would naturally be exposed to over a 10-day period in everyday life.
Images are produced instantly onto X-Ray film and are available immediately after the scan. However, a radiologist will need time to review and analyse the images. Depending on the urgency of the condition, results may take a few days or be available sooner. Once ready, your doctor will contact you to arrange a follow-up appointment to discuss the findings.
