What is Pneumothorax? What are the imaging tests for pneumothorax?

What is a pneumothorax? Pneumothorax requires a variety of imaging tests to help doctors treat it more thoroughly. Today, let's take a look at the imaging examination methods of pneumothorax to help you have a more comprehensive understanding of pneumothorax. What is pneumothoraxThe pleural cavity is composed of a parietal and visceral layers of the pleura, and is a closed potential space that does not contain air. Any cause of a breakdown of the pleura, and air entering the pleural space, is called a pneumothorax. At this time, the pressure in the pleural cavity increases, and even the negative pressure becomes positive pressure, which compresses the lungs, obstructs the venous blood flow back to the heart, and produces different degrees of lung and heart dysfunction.Filtered air is manually injected into the pleural space to identify intrathoracic disease on x-rays, called an artificial pneumothorax. Pneumothorax caused by chest trauma, acupuncture, etc., is called traumatic pneumothorax. The most common pneumothorax is the rupture of lung tissue and visceral pleura due to lung disease, or the bullae and emphysema bubbles near the lung surface burst on their own, and air from the lungs and bronchial tubes escapes into the pleural space, which is called spontaneous pneumothorax. Let's take a look at the impact of pneumothorax on the test. Imaging test for pneumothorax is chest CT (noncontrast scan). Chest x-ray is the most commonly used test to diagnose pneumothorax, but it is less sensitive than CT for detecting pneumothorax. The sensitivity of CT for detecting a pneumothorax is influenced by factors such as the strength of the scanner and the experience of the observer. High-resolution CT in the Third Hospital of Beijing Medical University can overcome many adverse factors, especially in diagnosis
