Lung ultrasound has become an essential tool for rapid bedside assessment in critically unwell patients, proving helpful in assessment of COVID-19 due to logistics of cross-sectional imaging. Contrast enhanced ultrasound (CEUS) further characterizes sonographic features of COVID-19 as multiple areas of infarction, a finding not reproducible on other widely available imaging modalities. CEUS also has the benefit of being cheap, radiation-free, without risk of nephrotoxicity, and can be performed at the bedside. It is predicted that lung CEUS in COVID-19 may help guide prognosis and management. We describe three cases of CEUS in COVID-19.
