What to Expect from a Chest X-Ray PA View Test? – Credihealth Blog


The posteroanterior (PA) chest view evaluates the lungs, bony thoracic cavity, mediastinum, and major vessels. The most frequent radiological examination in the emergency room is a chest x-ray. Therefore, a chest x ray pa view is commonly used as a diagnostic tool for acute and chronic illnesses affecting all thoracic cavity organs. In addition, the PA view is the most accurate plain radiograph for patients with severe abdominal discomfort to diagnose pneumoperitoneum or free intraperitoneal gas.

The chest x-ray pa view is safe to administer to both ambulatory and trauma patients. Their doctor may also request right and left oblique and lateral views for more research on the PA projection. To prevent the lungs’ full expansion, an upright position must be maintained as much as the patient can manage. In addition, the best way to see pleural effusions, pneumothorax, atelectasis, and other signs of infections is in an upright position.

What is X-Ray Chest PA View?

A chest X-ray PA view (posteroanterior) is an imaging procedure that uses X-rays to examine the structures and organs in your chest. It can aid in identifying certain lung and heart conditions and viewing the chest’s interior organs, such as the diaphragm and food pipe.

This scan is carried out to check for fractures or injuries to the chest wall’s bones to rule out lung conditions such as pneumonia and identify underlying cardiac diseases like heart enlargement. Even though the entire test could last up to 15-20 minutes, the actual radiation exposure period is typically less than a second.

Why is the Purpose of  X-Ray Chest PA View?

The X-Ray examination is done to evaluate any abnormalities in the heart, chest wall, and lungs. The doctor may suggest a chest X-ray if they suspect your symptoms are connected to problems in your chest. Here are a few reasons why a chest X-ray PA view is advised:

  • To identify any chest wall bone fractures or injuries (including the collar bone, breastbone, ribs, and shoulder blade)
  • To identify some lung conditions such as infections, tumors, or pneumothorax (presence of air between lungs and chest wall)
  • To identify underlying cardiac conditions such as heart enlargement, fluid surrounding the heart, or issues with the heart valve.
  • To identify any food pipe issues, such as infections, inflammations, or abnormal growth
  • To determine whether the diaphragm has been perforated (by the presence of free air in the chest)
  • To identify any potential birth abnormalities in the internal organs or the tissues of the chest wall

A chest X-ray is also used to determine the size and shape of your heart. Your heart’s size and form abnormalities may indicate that your heart is not functioning correctly.

Doctors occasionally use chest X-rays to check on you following a chest operation. In addition to ensuring you don’t have any air leaks or fluid accumulation. They also check the positions of any implanted objects.


Chest X-rays require very little preparation, and you must remove any jewelry, eyeglasses, body piercings, or other metal from your body. In addition, let your doctor know if you have a surgically implanted device, such as a pacemaker or heart valve. 

Positions of the Patient

  • When the patient faces the upright image receptor, its superior edge is 5 cm above the shoulder joints.
  • The chin is elevated such that it is outside of the field of view.
  • The shoulders are rotated anteriorly to allow the scapulae to shift laterally off the lung fields. It can be done in one of two ways:
  • palms placed on the back of the hips, rolling either the anterior or posterior
  • Focus is centered on the lateral movement of the scapulae while hands are hugged around the image receptor.
  • To move the clavicles below the lung apices, the shoulders are lowered.

You must notify the technician if you are pregnant. The baby is not exposed to the X-radiation ray because it could damage the unborn child. The technician will take the necessary steps for your baby’s safety if an X-ray is needed.


Doctors agree that the diagnostic advantages of X-rays make the modest amount of radiation exposure beneficial. However, experts do not advise getting an X-ray if you are pregnant. This is due to the risk of radiation to your unborn child. Instead, tell your doctor right away if you think you’re pregnant.


The organs in your chest can be seen in a black-and-white image created by a chest X-ray. Radiation-blocking structures are white, while radiation-allowing structures are black.

Your bones are so dense that they seem white. A lighter region can also be seen around your heart. The darker areas around your lungs on the scans are packed with air, blocking very little radiation.

An expert in interpreting X-rays and other imaging tests, known as a radiologist, examines the images to look for signs of heart failure, fluid around the heart, cancer, pneumonia, or other conditions.

Your physician will check the findings with you and prescribe any potential therapies, additional tests, or procedures that could be required.

Post Chest X-ray

The images from a chest X-ray are typically developed on big sheets of film in a lab. Your doctor can examine you against a bright background and look for various issues, such as cancers and broken bones.

Additionally, a radiologist reviews the pictures and provides your doctor with their analysis. Finally, your doctor will review your X-ray results with you at a follow-up appointment.
