Ultrasonic applications in the lungs

In medical diagnosis, using these sound waves to generate different reflection, refraction and attenuation characteristics through different media interfaces can help doctors examine organs in a patient's body in a non-invasive way. The examination process is very simple. Inspectors usually hold a "probe" coated with a "gel" liquid and place it on the patient to slowly scan the organs in the body.

ultrasound for lung

Ultrasound is now widely used in diagnosis of obstetrics and gynecology, liver, kidney and cardiology. In contrast, the structure of the lung is generally more difficult to display because the air in the normal lung obstructs the normal operation of ultrasound. However, when water accumulates in the pleural cavity surrounding the lungs, ultrasound can be used to observe and guide doctors to safely collect the hydrostatic fluid for testing and even drainage to reduce the asthma symptoms in patients. Because the lungs are close to the heart, liver, and spleen, ultrasound guidance can reduce damage to the lungs and these organs during the extraction process. In addition, lung or pleural diseased tissues (such as tumors) that are close to the body surface and chest wall can also be guided by ultrasound to perform needle aspiration tests. The process is quite simple and can be performed under local anesthesia, usually without hospitalization.

In the past, bronchoscopy was usually required to examine tissues in the lungs or bronchial tubes. However, this kind of endoscope is often beyond the reach of the lungs and lymphatic tissues outside the trachea, and requires other routes or even general anesthesia to obtain the answer. Fortunately, the "bronchoscopic ultrasound" examination introduced in recent years uses a slim ultrasound probe installed at the end of the bronchoscope, so that a respiratory doctor can simultaneously guide the ultrasound to extract the lung tissue or lymph glands close to the trachea for tissue analysis when examining the bronchus. .

With the development of technology, in addition to the increasing application range of ultrasound, the machine itself has also developed to be more lightweight. At present, models similar in size to laptop computers and even smartphones have appeared, enabling doctors to provide simpler examinations for patients. A convenient choice.
