Zwanger-Pesiri features the latest ultrasound (sonography) equipment at each of our eight facilities. Our ultrasound units have features that allow a broad range of examinations, including those involving blood flow.

Ultrasound is painless and safe. It involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. Since ultrasound does not use ionizing radiation (x-ray), it can be safely used to image the growing fetus and mother. Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.

Color Flow Doppler

We utilize color flow doppler ultrasound to evaluate blood as it flows through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck. Doppler ultrasound permits real-time information that cannot be obtained by other method by using reflected sound waves. The movement of blood cells causes a change in pitch of the reflected sound waves (Doppler effect). It can show reduced blood flow due to blockages in the arteries that can cause a stroke, or blood clots in veins.
