The largest study of ultrasound for #COVID19 to date (that I'm aware of) - retrospective, 30 pts with COVID confirmed via PCR, who underwent both lung US and CT
Lung US was compared to CT which was used as the reference standard

-6 region scan per hemithorax (anterior, lateral, posterior divided into upper and lower regions)
-scanning in BOTH longitudinal and transverse
