A sonogram, also known as an ultrasound, uses sound waves to generate images of internal organs and structures. They are frequently used to monitor pregnancy, as they can create pictures of fetal development. Unlike X-rays, ultrasounds do not use radiation and there are no known risks involved.

Ultrasounds can also be used to help Dr. Ayalon diagnose causes of pain, abnormal bleeding, menstrual problems, and infertility. For pregnant women, an ultrasound can reveal a baby’s heartbeat, sex, and risk for Down’s Syndrome and other abnormalities. Ultrasounds are particularly useful for monitoring and diagnosing risky pregnancies and miscarriages.

For typical ultrasounds, you will lie on your back on an examination table and have a special conducting gel placed on your skin. The doctor will place the device on your lower abdomen to create the images. The procedure is essentially free of discomfort.

Transvaginal ultrasounds are similar to regular ultrasounds, but they are created using conduction wands. The procedure requires you to be undressed below the waist and positioned in stirrups. The doctor will then place the conduction wand in the vagina and adjust it for the best possible image.
