Ultrasound imaging, also called sonography, is a method of obtaining images of inside the body using high-frequency sound waves. There is no radiation involved in ultrasound imaging, and there are no known harmful effects to the human body.

Ultrasound is perhaps best known for providing expectant parents with the first picture of their unborn child. Ultrasound images are captured in "real time" and they can show the movement of a fetus as well as complex bodily functions such as blood flow and heart valve operation. The procedure is also used to guide needle biopsies, in which needles are used to sample cells from certain organs or tissue for laboratory testing.

Ultrasound scanners consist of a computer, video display screen and a transducer (a small, hand-held device.) To perform an ultrasound exam, a technologist will spread a special gel on the part of the body being examined and press the transducer against the skin to obtain the image. The patient can view the images on a screen positioned just for their view. The exam usually takes less than 30 minutes. A radiologist (physician) will analyze the images and report the results to your physician.

We offer both conventional and 4-D ultrasound exams. 4-D imaging uses a special computer software to generate a picture like image and, for unborn children, the picture can be obtained at approximately 28 weeks of gestation. A complimentary 4-D exam is offered to all patients who have their diagnostic sonogram at the Women's Imaging Center. The parents will receive a copy of the 4-D images on a CD as a keepsake and to share with family and friends.

If you are having an ultrasound exam, please follow your physician's orders prior to your appointment. If you do not follow the orders, your exam may have to be delayed or rescheduled.
