Ultrasound-guided refers to the use of ultrasound technology to guide medical procedures such as injections, biopsies, and surgeries. By using ultrasound imaging, healthcare professionals are able to visualize internal structures in real-time, allowing for more accurate and precise placement of needles or instruments. This technology is commonly used in various medical specialties including radiology, anesthesiology, and obstetrics to improve patient outcomes and reduce the risk of complications. Overall, ultrasound-guided procedures offer a safe, minimally invasive, and effective approach to diagnosing and treating a wide range of medical conditions.
