COVID-19 is routinely studied using lung ultrasound and quantifying the disease by the “white lung” appearance of multiple B-lines targeting the pulmonary parenchyma. All modern sonographic equipment offers color Doppler features, which have not been fully utilized in the differential diagnosis of inflammatory and malignant lesions. In addition to the sonographic characteristics of the B-mode image, the type of vascularization is important for clinical assessment of a lesion in terms of differential diagnosis. In sonographic examinations, the well-established procedures of power or color Doppler sonography and contrast enhanced ultrasonography (CEUS) are used.

Recently color-Doppler sonography characteristics of bacterial pneumonia, obstructive atelectasis, lung infiltrates and bronchial carcinoma have been described. Preliminary studies show that CEUS can be performed on the chest in some clinical settings. Various diseases of the lung are characterized by specific contrast sonography findings. The purpose is to describe color/power Doppler sonography and CEUS findings in the presence of peripheral lung consolidations.
