The Role of the Lung Ultrasound in Coronavirus Disease 2019: A Systematic Review.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has now infected six million people and is responsible for nearly four hundred thousand deaths. We review the potential role of the lung ultrasound to evaluate its benefits and potential roles to compare it to the current gold standard of computed tomography. A literature search was carried out utilizing electronic search engines and databases with COVID-19. Keywords related to the lung ultrasound (LUS) were used to refine this search - only the relevant articles found are cited. This review showed that there exists a strong correlation between the CT and LUS scan in COVID-19. Prominent features include the vertical B-lines, thicker pleural lines, and subpleural consolidation. Potential roles include reducing transmission between health-care workers and monitoring the progress of the disease. However, the current research is scarce compared to well-established imaging modalities, and as such, there is a necessity for more research to confirm the findings of this review.
