ShearWave Elastography Ultrasound
What is an Ultrasound?
Shear wave Elastography is a specialized type of Ultrasound that uses high-frequency sound waves, generated by a handheld device called a transducer. The transducer is placed on the skin where it uses the echoes created by the sound waves to create images of the internal organs.
Ultrasound does not involve radiation, which is one of the reasons that it is routinely used to examine fetuses in utero. There are many other applications for ultrasound, such as evaluating abdominal and pelvic organs, assessing blood vessels for clots or atherosclerotic plaque, examining the superficial structures of the neck and extremities, and providing guidance for biopsies or for draining fluid collections.
Preparing for your exam
No food or drink 8 hours prior to your exam, except for water to take medications. You may be asked to remove some or all of your clothing and wear a scrub top, scrub pants or a gown during the exam.
