COVID-19 is a viral disease also known as SARS-CoV-2 or severe acute respiratory syndrome coronavirus. The diagnosis is made by a positive PCR test, which is highly specific. CT has a higher sensitivity but lower specificity and can play a role in the diagnosis and treatment of the disease.

CT can play a role in:

-Triage of patients:
- No COVID-19
- Possible or most likely COVID-19
- Severity of the disease
-Prediction of worsening
-Prediction of improvement
-Problem solver

Some published clinical guidelines recommend chest CT for patients with suspected COVID-19. The decision to use of CT for triage depends on many considerations:

-A priori chance of COVID-19 infection.
-CT availability, for instance, can one CT be used as Corona- CT or
is there a CT near the emergency room.
-Clinical suspicion in patients with negative PCR
