Abstract Background: Ultrasound is used to observe the imaging manifestations of COVID-19 in order to provide reference for real-time bedside evaluation.Purpose: To explore the ultrasonic manifestations of peripulmonary lesions of non-critical COVID-19, so as to provide reference for clinical diagnosis and efficacy evaluation.Materials and Methods: The clinical and ultrasonic data of 20 patients with clinically diagnosed non-critical COVID-19 treated in Xi'an Chest Hospital during January and February 2020 were retrospectively analyzed. Conventional two-dimensional ultrasound and color Doppler ultrasound were used to observe the characteristics of lesions. Results: All 20 patients (40 lungs and 240 lung areas) had a history of travel, residence or close contact in/with Wuhan, and 5 of them caught COVID-19 after family gatherings. Lesions tended to occur in both lungs. Lesions in the lung areas: 14 in L1+R1 area (14/40), 17 in L2+R2 area (17/40), 17 in L3+R3 area (17/40), 17 in L4+R4 area (17/40), 20 in L5+R5 area (20/40), and 28 in L6+R6 area (28/40). Lesion types: rough and discontinuous pleural line (36/240), subpleural consolidation (53/240), air bronchogram sign or air bronchiologram sign in subpleural peripleural consolidation (37/240), visible B lines (91/240), localized pleural thickening (19/240), localized pleural effusion (24/240), poor blood flow in the consolidation detected by color Doppler ultrasound (50/53).Conclusion: The non-critical COVID-19 has characteristic ultrasonic manifestations, which are visible in the posterior and inferior areas of the lung. The lesions are mainly characterized by a large number of B lines, subpleural pulmonary consolidation and poor blood flow. Lung ultrasound can provide reference for the clinical diagnosis and efficacy evaluation. Chinese Clinical Trial Registry: ChiCTR2000030032Approval for Scientific Research Project: No. 2020-S0001

ABSTRACT This review aims to provide the reader with an overview of the potential clinical applications in three-dimensional (3D) Doppler ultrasound for the evaluation of vascularity and blood flow within the placenta. Significant innovations have recently occurred, improving the visualization and evaluation of placental vascularity, resulting from enhancements in delineation of tissue detail through electronic compounding and harmonics, as well as enhancements in signal processing of frequencyand/ or amplitude-based color Doppler ultrasound. Spatial representation of vascularity can be improved by utilizing 3D processing. Greater sensitivity of 3D Doppler ultrasound to macro- and microvascular flow has provided improved anatomical and physiologic assessment throughout pregnancy. The rapid development of these new sonographic techniques will continue to enlarge the scope of clinical applications in placental studies. Three-dimensional Doppler sonography is a unique ultrasound technique that enables assessment of vascular signals within the whole investigated area. Homodynamic changes included in the process of placentation are one of the most exciting topics in the investigation of early human development. How to cite this article Zalud I.
