Chest X-Ray Views With Contrast, Posteroanterior

What is this test?

This is an imaging test that uses X-rays and contrast material to create pictures of the chest. Contrast can make certain tissues, blood vessels, or spaces easier to see. The posteroanterior view is taken with you standing or positioned so the X-ray beam passes from your back to your front.

Why might I need this test?

A contrast chest X-ray may be ordered to investigate suspected problems involving the lungs, heart, major blood vessels, or chest wall. It may be used to evaluate symptoms such as chest pain, shortness of breath, cough, or unexplained changes seen on another chest X-ray.

How is the test performed?

You will usually stand or lie in a position that allows the X-ray machine to take the required chest views. Contrast material may be given by mouth or through a vein, depending on the specific examination. The images are then reviewed by a radiologist.

How do I prepare for the test?

Preparation depends on how the contrast is given and the facility's instructions. You may need to avoid eating or drinking for a period, and you should tell the care team about any prior contrast reaction, kidney disease, relevant medication allergies, or possible pregnancy.
