Soft tissue ultrasound is a medical imaging technique that uses high-frequency sound waves to create detailed images of soft tissues in the body. Unlike X-rays or CT scans, ultrasound does not involve ionizing radiation, making it a safer option for certain patients, including pregnant women.
Ultrasound uses sound waves with frequencies higher than the human ear can hear (typically above 20,000 hertz). A transducer sends these sound waves into the body, and they bounce back as echoes when they encounter different tissues. The echoes are then used to create real-time images.
Ultrasound may be limited in imaging structures deep within the body, and the image quality can be affected by factors such as obesity or the presence of gas in the gastrointestinal tract.
A gel is often applied to the skin to improve the transmission of sound waves. The transducer is then moved over the area of interest to obtain images.
Soft tissue ultrasound is a valuable tool in medical diagnostics, providing information that helps clinicians assess and diagnose various conditions in a non-invasive manner. It is commonly used in conjunction with other imaging modalities to provide a comprehensive evaluation of a patient's health.
