Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It helps diagnose the causes of pain, swelling and infection in the body's internal organs and to examine an unborn child (fetus) in pregnant women. In infants, doctors commonly use ultrasound to evaluate the brain, hips, and spine. Ultrasound is safe, noninvasive, and does not use radiation. Certain exams may include a Doppler ultrasound study;
Doppler is a special ultrasound technique that evaluates movement of materials in the body. It allows the doctor to see and evaluate blood flow through arteries and veins in the body.
There are three types of Doppler ultrasound:
Color doppler: uses a computer to convert Doppler measurements into an array of colors to show the speed and direction of blood flow through a blood vessel.
Power Doppler is a newer technique that is more sensitive than color Doppler and capable of providing greater detail of blood flow, especially when blood flow is little or minimal. Power Doppler, however, does not help the radiologist determine the direction of blood flow, which may be important in some situations.
Spectral Doppler displays blood flow measurements graphically, in terms of the distance traveled per unit of time, rather than as a color picture. It can also convert blood flow information into a distinctive sound that can be heard with every heartbeat
Ultrasound requires little to no special preparation. Our staff will inform you how to prepare, including whether you should not eat or drink beforehand. Leave jewelry at home, do not wear anything scented like perfumes, heavily scented lotions and wear loose, comfortable clothing. You may need to change into a gown.
