Can An X-ray Show Infection

Lab testing for COVID-19 (also known as the novel coronavirus or SARS-CoV2) has increased greatly since the virus spread across the globe in spring 2020. Current evidence suggests that chest CT scans and x-rays are generally NOT specific enough to either diagnose or rule out COVID-19 on their own. But imaging does have a limited role to play: when used with lab tests, a medical history and a physical exam, CT scans or x-rays can be helpful for diagnosing COVID-19 or determining the severity of the disease in some patients.

Some patients with COVID-19 have also reported fatigue, muscle aches, a loss of smell (anemia) or taste, and up to 10% have GI-related symptoms such as diarrhea. Click here for the Centers for Disease Control (CDC)’s information on people who may be at higher risk.

Droplets containing the viruses are expelled when an infected person talks, coughs or sneezes. Identifying and isolating patients infected with COVID-19 is an important step in managing this global pandemic.

To stop the spread, health care providers need to identify who infected people have come in contact with. In patients who develop COVID-19-like symptoms or who meet certain travel or exposure criteria, testing is done using a special swab in the nose or back of the throat.

Some centers, such as the University of Virginia, have developed a test that is performed on site with results available within 24 hours. While patients with COVID-19 can show an abnormality on either a chest x-ray or CT scan, many other lung problems can look very similar.

For this reason, most experts and medical societies advise against the use of an imaging test alone to diagnose or rule out COVID-19. The American College of Radiology (or ACR), which represents nearly 40,000 radiologists in the United States, has issued guidance that CTs and x-rays should not be used as a first-line tool to diagnose or screen for COVID-19.

But even with careful cleaning, there is a risk that the virus could remain on a surface in a CT scanner room. Additionally, moving potential COVID-19 patients to and from a CT scanner room increases the risk of spreading the virus inside of healthcare facilities.

It also means that fewer CT scanners would be available for other vulnerable patients who need this imaging test. For patients with severe symptoms, imaging might help to assess the seriousness of the disease.

And when used with lab tests, a thorough medical history and a physical exam, CT scans or x-rays can be helpful for determining a plan of care for a patient. Contact your provider immediately if you have any of the CDC’s emergency warning signs for COVID-19, including trouble breathing or persistent chest pain.

If you have symptoms but don’t have access to a laboratory test, stay home and follow the CDC’s guidelines for protecting others. Article reviewed and edited by Arun Krishna, MD, MPH, and Alan Mutsuhito, MD. Last updated 9/10/2020.

Barium, a contrast medium delivered in a drink or an enema, can help reveal problems in your digestive system. If your child has swallowed something such as a key or a coin, an X-ray can show the location of that object.

Some people worry that X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer. The amount of radiation you're exposed to during an X-ray depends on the tissue or organ being examined.
