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
All US scans were performed at the bedside by a single physician
-6 region scan per hemithorax (anterior, lateral, posterior divided into upper and lower regions)
-scanning in BOTH longitudinal and transverse
-used BOTH convex and linear probes
-5-8 min per scan
2/
Yet *another* scoring system:
0 pt: normal pleural line, A lines, <3 B lines
1 pt: >3 B lines
2 pt: coalescent B lines
3 pt: consolidation
Total score summed up (0-36 pt):
-none: 0 pt
-mild: 1-7 pt
-moderate: 8-18 pt
-severe: 19+ pt
