Can dry cough affects the result for chest x ray?

Yes, a dry cough can affect the results of a chest X-ray.

During a chest X-ray, a small amount of radiation is used to create images of the chest. The X-rays pass through the body and are absorbed by dense tissues, such as bones and muscles. The resulting images show the outline of the heart, lungs, and other structures in the chest.

A dry cough can cause the lungs to become inflamed and filled with fluid. This can make it more difficult for the X-rays to pass through the lungs, resulting in images that are less clear. In some cases, a dry cough can even cause the lungs to appear white on the X-ray, which can make it difficult to see other structures in the chest.

If you have a dry cough, it is important to tell your doctor before getting a chest X-ray. Your doctor may recommend waiting until the cough has cleared up before having the X-ray.
