Sonography is a diagnostic medical procedure that uses high-frequency sound waves (ultrasound) to produce dynamic visual images of organs, tissues or blood flow inside the body. This type of procedure is often referred to as a sonogram or ultrasound exam.
A Diagnostic Medical Sonographer is a highly skilled professional who uses specialized equipment to create images of structures inside the human body that are then used by physicians to make a medical diagnosis. The sonographic process involves placing a small device called a transducer against the patient’s skin near the body area to be imaged. The transducer works like a loudspeaker and microphone because it can transmit and receive sound. It sends a stream of high-frequency sound waves into the body, then detects the sound waves as they bounce off internal structures. Different structures in the body reflect these sound waves differently. The reflected sound waves are analyzed by a computer to make an image of the structure(s) on a monitor or that can be recorded on hard copy images.
Sonography can also recognize blood or fluid flow. The computer can especially recognize fluid that is flowing toward or away from the transducer and uses color overlays on the image to show direction of flow. Very hard and dense tissues or empty spaces, such as organs filled with gas, do not conduct ultrasound waves and therefore cannot be viewed on a sonogram.
Sonography is often used before moving to imaging technologies that have more potential for complications.1  Computerized tomography (CT) scanning exposes you to significant levels of radiation. Magnetic resonance imaging (MRI) uses an extremely strong magnet to capture the image. The strength of an MRI magnet can limit its use in patients with metal in their bodies (braces, for example).
