Abstract

Background: Thousands of new patients are diagnosed with coronavirus disease 2019 (COVID-19) daily worldwide.
We reviewed the role of chest imaging in the diagnosis and treatment of patients with COVID-19.
Current Concepts: Chest imaging is not recommended as a primary diagnostic tool for COVID-19. However, when real-time polymerase chain reaction is difficult to perform or when COVID-19 is strongly suspected, chest imaging can assist in the diagnosis. Thus, chest imaging is recommended for high-risk patients and patients with worsening respiratory symptoms, but not for asymptomatic patients. Bilateral peripheral pneumonia is a typical imaging finding in patients with COVID-19. However, there are cases where chest imaging shows atypical findings or appears normal. The extent of COVID-19 pneumonia on chest imaging is related to the severity of the disease. The presence and extent of pneumonia on chest imaging can help monitor patients, select appropriate treatment agents, determine whether the patient should be hospitalized, and predict the prognosis.
Discussion and Conclusion: Appropriate use of chest imaging is needed for clinicians to help triage patients with COVID-19 and decide on the treatment plan.
