What is Ultrasound?
Ultrasound imaging (also called “sonography”) uses high-frequency sound waves to create visual images of the internal body structures. As the sound waves pass through the body, some of the waves are absorbed by the body’s tissues, while others are reflected back. The reflected sound waves are measured and displayed by a computer, which then creates a real-time image on a monitor. The sonographer will electronically store the images, which will be studied and evaluated by the radiologist.
Many patients are familiar with the use of ultrasound during pregnancy. However, it also offers several other diagnostic applications. Ultrasound can detect the source of pain or inflammation inside the body and can reveal infection or tumors. It is often used for patients with suspected gallstones. Ultrasound can also evaluate the arteries and veins for narrowing, blockages, or clots.
Your Ultrasound Exam:
You will be asked to lie down on an examination table. The sonographer will apply a clear gel to the skin over the area that is being studied. The sonographer passes a small device, referred to as a transducer, over the skin. The sound waves that create the ultrasound images are sent through the transducer. You will be able to get dressed and leave immediately following the procedure. Most exams take less than 30 minutes.
