Imaging
Chest CT imaging of COVID-19 patients typically demonstrate ground-glass
opacities, multifocal patchy consolidation, and/or interstitial changes
with a peripheral distribution.24 In one study, the
authors found that Chest CT scans had higher sensitivity for diagnosis
of COVID-19 (88%) as opposed to initial RT-PCR using throat swabs
(59%).25 Another study assessed radiologists’ ability
to distinguish COVID-19 pneumonia from non-COVID-19 pneumonia. It found
sensitivities among radiologists to be between 73-93% and specificities
to be between 93-100%.26 At this time, however, the
majority of radiology societies do not recommend routine screening for
COVID-19 with chest CT.27
