B-ultrasound

B-ultrasound examination is used in the following cases: 1. Determine the location and nature of pleural lesions; understand the shape, thickness, and continuity of the pleura; whether there is a tumor; whether the chest wall or ribs are involved; No adhesion, observe whether there is pleural effusion. 2. Peripheral lung occupying lesions: understand the pathogen's location, size, shape, physical properties, internal structure and surrounding anatomy. 3. Lung atelectasis and pneumonia: observe the degree of lung gas, the structure of the atelectic lung, the presence or absence of tumors, the shape, position, and movement of the collapsed lung lobe. 4. Pleural fluid (pleural effusion): Estimate the amount of pleural fluid, determine its properties, and observe the presence of parcels, multifamily, and fibrosis. 5. Mediastinal space-occupying lesions: Understand the size, morphology, internal structure of the lesions, and the shape and relationship of adjacent large vessels. 6. Diaphragmatic lesions: Observe the shape, position, and activity of the diaphragm. 7. Percutaneous puncture cytology and tissue biopsy of chest wall, lung, and mediastinal space lesions under ultrasound guidance.
