According to an article published in American Journal of Roentgenology (AJR), lung ultrasound (US) was highly sensitive for detecting abnormalities in patients with COVID-19, with B-lines, a thickened pleural line, and pulmonary consolidation the most commonly observed features.

Researchers performed lung US on consecutive patients with positive RTPCR test results for SARS-CoV-2, using the Fisher exact test to compare the percentages of patients with each US finding between groups with different symptom durations and disease severity.

All 28 patients (14 men and 14 women; age range, 21-92 years) had positive findings on both lung US and chest CT. On US, B-lines were present in 100% of patients, and 19 (67.9%) patients had pulmonary consolidation. Thickened pleural lines were observed in 17 patients (60.7%), and only one patient (3.6%) showed a small amount of pleural effusion.

"A thickened pleural line was more frequently observed on US in patients with longer time intervals after the initial onset of symptoms," researchers noted, adding that pulmonary consolidations -- visualized as tissuelike hypoechoic regions, reflecting highly reduced air flow and increased quantity of inflammatory cellular exudate -- were more common in severe and critical cases.

Acknowledging that portable radiography could be just as useful in evaluating consolidation, "a bedside portable, handheld US system or even a robot-assisted tele-US system further minimizes the number of health care workers and medical devices exposed to COVID-19," wrote researchers.

The authors also proposed that severity scoring for lung US, similar to CT severity scores, should be developed to facilitate more accurate comparisons in future studies.
