Abstract

•
Current guidelines recommend the use of unenhanced chest CT as first-line imaging in patients suspected of COVID-19 pneumonia.
•
In unselected COVID-19 patients, the prevalence of PE at baseline is no different from the one in COVID-19 negative patients.
•
There is no clear benefit to routinely perform CTPA as first-line imaging modality in patients suspected of COVID-19 pneumonia
