Vascular Ultrasound Preparation Explained by Hill Medical

How should I prepare for a Vascular Ultrasound?

You should wear comfortable, loose-fitting clothing for your vascular ultrasound exam. No other preparation is required.

How does the Vascular Ultrasound procedure work?

Ultrasound imaging is based on the same principles involved in the sonar used by bats, ships at sea and anglers with fish detectors. As the sound passes through the body, echoes are produced that can be used to identify how far away an object is, how large it is, its shape and its consistency (fluid, solid or mixed).

The ultrasound imaging transducer functions as both a loudspeaker (to create the sounds) and a microphone (to record them). When the transducer is pressed against the skin, it directs a stream of inaudible, high-frequency sound waves into the body. As the sound waves echo from the body's fluids and tissues, the sensitive microphone in the transducer records tiny changes in the sound's pitch and direction. These signature waves are instantly measured and displayed by a computer, which in turn creates a real-time picture on the monitor. Still frames of the moving picture are usually "frozen" to capture a series of images. Blood flow changes the pitch of the sound beam; this Doppler effect can be heard or detected on the image as color or displayed graphically.
