The incidence of breast cancer ranks first among female malignant tumor. With the increase of the sensitivity of color Doppler ultrasound blood flow, the blood flow distribution in and around the tumor can be clearly displayed, and the analysis of hemodynamic parameters is provided, which provides convenience for the study of tumor blood flow characteristics. Studies have shown that tumor cells can secrete a substance called angiogenesis factor, which makes the tumor site form a rich vascular network to promote tumor growth and metastasis. The tumor has many new blood vessels, abnormal structure, thin wall, lack of muscle layer, and is prone to form arteriovenous rash. These characteristics provide a pathological basis for color Doppler flow imaging (CDFI) for the diagnosis of breast cancer. This article discusses the role of two-dimensional sonographic features in the differential diagnosis of benign and malignant breast masses, CDFI was used to study the blood flow distribution and hemodynamic characteristics in benign and malignant breast masses; explore the value of blood flow characteristics and blood flow parameters in the differential diagnosis of breast masses. The experimental results show that the detection rate of blood flow signals and the classification of blood flow signals in the malignant group are higher than those in the benign group, mainly level II and III blood flow, and the irregular branched blood flow is more common, especially when the tumor appears penetrating blood flow supports the diagnosis of malignancy. PSV, RI and PI have a certain differential meaning in the diagnosis of benign and malignant breast masses. PSV, RI and PI of malignant masses are higher than benign masses. For tumors without obvious necrosis, the larger the tumor diameter, the richer the blood flow and the higher the blood flow grade is. The malignant tumors have more blood flow than the benign ones.

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.
