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.

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.
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.
Additionally, moving potential COVID-19 patients to and from a CT scanner room increases the risk of spreading the virus inside of healthcare facilities. 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. COVID-19, the disease caused by SARS-CoV-2 (a new type of coronavirus), continues its spread throughout the United States.
The phrase “bilateral multifocal” means that the abnormalities occur in different locations in both lungs. Small pleural effusions : This is abnormal fluid that develops in the spaces around the lungs.
Nevertheless, suspicious findings on chest CT are a valuable clue (along with the clinical presentation and exposure history) that a patient may have COVID-19. Chest CT may also be used as an initial tool to assess disease severity, as well as to monitor for progression or resolution of disease.
The most reliable test for the diagnosis of SARS-CoV-2 infection is an pharyngeal or nasopharyngeal polymerase chain reaction (PCR) assay, involving a throat swab or a swab of the place where back of the nose meets the throat. However, some reports have suggested a sensitivity of 60-70%, meaning that there may be a significant number of infected people who actually have a negative test.
Some reports from China have suggested that, in some patients with COVID-19 pneumonia, abnormalities on chest CT may appear despite negative swab tests. This, combined with the initial lack of sufficient test kits, has led some medical practices to request chest CTs to screen patients for the disease. A chest CT may be helpful if used carefully in sick, hospitalized patients, as it may be useful to gauge the severity and progression of the disease.
It is best to follow the recommendations set by groups like the CDC, whose guidelines are supported by the most solid available evidence. Very well Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
Read our editorial process to learn more about how we fact-check and keep our content accurate, reliable, and trustworthy. The most affected population groups are children under 59 months and adults over 50 years of age.
However, the impact of chest X-rays in terms of how they may change patient recovery in suspected chest infection has not been evaluated. We focused on whether the use of chest X-rays compared to not using them led to improved outcomes such as a faster recovery rate, less time in hospital and fewer complications for the patient.
We did not investigate the use of chest X-rays as a tool in the diagnosis of chest infections or the differences in the interpretation of X -rays between doctors. In both adults and children, chest X-rays did not result in significant differences in recovery time.
Although both studies suggest that chest X-rays do not improve patient outcomes, it is not clear if this finding can be applied to all populations and settings. Our conclusions are limited due to the lack of complete data available and by the risk of bias of the studies.
This conclusion may be weakened by the risk of bias of the studies and the lack of complete data available. Acute lower respiratory tract infections (Artist) (e.g. pneumonia) are a major cause of morbidity and mortality and management focuses on early treatment.
The efficacy of chest radiographs as a tool in the management of acute Artist has not been determined. Two review authors independently applied the inclusion criteria, extracted data and assessed risk of bias.
Both included trials concluded that the use of chest radiographs did not result in a better clinical outcome (duration of illness and of symptoms) for patients with acute Artist. The study in adults also reports that chest radiographs did not affect the frequencies with which clinicians ordered return visits or antibiotics.
Hospitalization rates were only reported in the study involving children, and it was found that a higher proportion of patients in the radiograph group (4.7%) required hospitalization compared to the control group (2.3%) with the result not being statistically significant (P = 0.14). None of the trials report the effect on mortality, complications of infection or adverse events from chest radiographs.
