Chest X Ray Test: Preparation, Procedure and What to expect?

A chest X ray is a procedure that uses a beam of radiation to examine the health of your heart, lungs and bones. Healthcare providers often suggest this test to detect and treat certain health conditions. Let us get into detail to know more about this test, how it works and what to expect.

What can a chest X ray detect?    

It is a test that creates images of your bones, lungs and heart. In medical terms, it is also called a chest radiography or CXR. This test helps your doctor detect health conditions that cause symptoms in your heart or lungs, and some of these include:

• Chest pain
• Experiencing difficulty breathing
• Having a fever with other signs of infection
• Chronic cough

This test may also be suggested to detect or monitor health issues, such as:

• Lung cancer
• Pneumonia
• Tuberculosis
• Ribcage injuries
• Chronic obstructive pulmonary disease (COPD)
• Congestive heart failure

How does the procedure work?    

Your body tissues vary in thickness, and as radiation passes through your body, each structure allows a different amount of radiation to pass through.

If your bones are very thick and do not allow much radiation to pass through, they will appear white on the X-ray image. On the other hand, your lungs allow more radiation to pass through, so they look gray on the X-ray.

Healthcare providers examine the colors and shading in detail to detect abnormalities and plan treatment.

Preparation

Chest X ray doesn't require any special preparation. However, when it is time of your appointment, make sure you wear loose, comfortable clothes that don't contain any metal fastenings like zippers, snaps or bra closures. You will also be advised to remove your jwellery as it may interfere with the images.

Procedure

A radiology technologist will take your chest X-ray, as they are specially trained. You will be asked to change into a medical gown, and the procedure will consist of two parts, such as:

You will stand with your chest against the metal plate of the X-ray machine with your hands on your hips to produce an image of the front of your chest.

You will stand with your side against the metal plate of the X-ray machine, with your arms in the air, to create an image of the side of your chest. 

During the test, you need to stay still and hold your breath for a moment, as any movement can cause a blurry image.

What to expect after the test?

After the chest X-ray, the healthcare professional may ask you to wait while they examine the images. If any image is blurry, a retake will be required.

Your doctor will analyse the images for normal and abnormal findings and discuss the next steps.

What do the test results indicate?    

After reviewing the test results, your doctor will explain the results:

Normal Chest X-ray: Shows clear images of the lungs, heart and a clearly outlined chest cavity with no visible nodules, tumours or masses. 

Abnormal chest X-ray: This can highlight changes in your organs such as an enlarged heart, fluid buildup in your lungs, cysts, broken ribs, and other irregularities.

Your healthcare provider may also suggest other screening tests, like a PET or CT scan, to gather more information about your health.

Final words    

A chest X ray test usually consists of two images- one taken from the front while the other is taken from the side. In some cases, a healthcare expert may also include images taken while you lie on your back and on your side. However, always make sure you share all the information with your healthcare provider, especially if you are pregnant, as it is recommended to limit radiation exposure until delivery. As a quick, simple, and non-invasive test, a Chest X-ray can help your doctor determine what kind of treatment you need.
