Ultrasound guidance is a technique used in various medical procedures to visualize internal organs and tissues using high-frequency sound waves. This technology allows for real-time imaging of anatomical structures, allowing healthcare providers to accurately guide medical instruments, such as needles or catheters, to specific locations within the body. Ultrasound guidance is commonly used in procedures such as biopsies, injections, and catheter placements, and is known for its accuracy, safety, and ability to reduce complications. This technology has revolutionized the field of minimally invasive procedures and has become an essential tool in many medical specialties, including radiology, cardiology, and obstetrics.
