Description
A chest X-ray is a quick and painless procedure that uses a small dose of ionizing radiation to produce images of the inside of the chest. This test is performed to: Identify lung infections like pneumonia or tuberculosis. Evaluate heart conditions, such as heart enlargement. A chest X-ray uses a focused beam of radiation to look at your heart, lungs and bones. Healthcare providers use chest X-rays to diagnose or treat conditions like pneumonia, emphysema or COPD. Chest X-rays are quick, noninvasive tests. Usually, you’ll know the results of your X-ray within one to two days. Air on an X-ray looks dark, so when the lungs are clear and healthy, that’s exactly how they should look: not quite black, because there is still tissue there, but still quite dark. If the lungs look like they have regions of density within them, that’s something to take note of.
