At present, the role of lung ultrasonography (LUS) has yet to be explored. The main purpose of this study was to evaluate the correlation between LUS findings and chest CT in patients confirmed to have (positive reverse transcription polymerase chain reaction [RT-PCR]) or clinically highly suspected of having (dyspnea, fever, myasthenia, gastrointestinal symptoms, dry cough, ageusia or anosmia) COVID-19. This prospective study was carried out in the emergency department, where patients confirmed of having or clinically highly suspected of having COVID-19 were recruited and underwent chest CT and concurrent LUS exam. An experienced emergency department physician performed the LUS exam blind to the clinical history and results of the CT scan, which were reviewed by two radiologists in consensus for signs compatible with COVID-19 (bilateral ground-glass opacities in peripheral distribution). A compatible LUS exam was considered a bilateral pattern of B-lines, irregular pleural line and subpleural consolidations. Between March and April 2020, 51 patients were consecutively enrolled. The indication for CT was a negative or indeterminate RT-PCR test (49.0%) followed by suspicion of pulmonary embolism (41.2%). Radiologic signs compatible with COVID-19 were present in 37 patients (72.5%) on CT scan and 40 patients (78.4%) on LUS exam. The presence of LUS findings was correlated with a positive CT scan suggestive of COVID-19 (odds ratio: 13.3, 95% confidence interval: 4.5-39.6, penCOVID-19Chest computed tomographyCoronavirus disease 2019SARS-CoV-2 Lung ultrasonographySevere acute respiratory syndrome coronavirus 2BetacoronavirusCOVID-19COVID-19 TestingClinical Laboratory TechniquesCoronavirus InfectionsFemaleHumansMaleMiddle AgedPandemicsPneumonia, ViralPredictive Value of TestsProspective StudiesRadiography, ThoracicReverse Transcriptase Polymerase Chain ReactionSARS-CoV-2SpainTomography, X-Ray ComputedUltrasonographyresearch article32771222open access10.1016/j.ultrasmedbio.2020.07.0031879-291XPMC7357528https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7357528https://pmc.ncbi.nlm.nih.gov/articles/PMC7357528/pdf
