Ultrasonography Test in Obstetrics and Gynecology (Pelvic or Pregnancy Ultrasound)

In ultrasonography, or ultrasound, sound waves are used to create images of internal soft tissue structures in the body. This test can be used to help diagnose issues with many organs and blood vessels. It is also used during pregnancy to view the baby in the uterus.

What is ultrasonography?

In ultrasonography, or ultrasound, high-frequency sound waves, inaudible to the human ear, are transmitted through body tissues. The echoes are recorded and transformed into video or photographic images. Ultrasound images help in the diagnosis of a wide range of diseases and conditions. The idea for ultrasonography came from sonar technology, which makes use of sound waves to detect underwater objects. This test is used to create images of soft tissue structures, such as the gall bladder, liver, heart, kidney, female reproductive organs—and even of babies still in the womb. Ultrasound can also detect blockages in the blood vessels. It cannot be used to image bones because they are too dense to penetrate. In addition, the intestinal tract and normal lung tissue are not easily identified with ultrasound because air or gas interfere with the production of ultrasound images. Ultrasound may be used with other diagnostic procedures or by itself.

What happens during the test?

During the test you will lie on a padded examining table. A warm, water-soluble gel is applied to the skin over the area to be examined. The gel does not harm your skin or stain your clothes. A probe is gently applied against the skin. If necessary, an ultrasound transducer may be inserted into the vagina. You may be asked to hold your breath briefly several times. If a vaginal ultrasound is required, the sonographer will let you know how to change your position. There is virtually no discomfort during the test. If a full bladder is required for the test, you may feel some discomfort when the probe is applied.

The ultrasound usually takes about 40 minutes to complete. Please refrain for cell phone use or video imaging. For pregnancy ultrasounds, 3D pictures are not a standard part of the examination and are not guaranteed.

Giving you the best care and overall patient experience during the ultrasound appointment is the main goal. Providing a tranquil, stress free environment with fewer distractions will help to provide the best quality ultrasound examination.
