What is an ultrasound?

An ultrasound is a form of medical imaging involving the use of high-frequency sound waves. Ultrasounds can also be called sonography or diagnostic medical sonography.

Ultrasounds are often used for diagnostic testing. Your provider performs most ultrasound exams outside of your body using a handheld device called a transducer. A transvaginal ultrasound assesses a woman’s reproductive organs.

Why is an ultrasound performed?

In women’s health care, an ultrasound might be performed for several reasons, such as to:

  • View the uterus of a pregnant woman to evaluate the fetus
  • Look for possible causes of abnormal uterine bleeding, pelvic pain, or other menstrual problems
  • Locate an intrauterine device (IUD)
  • Monitor infertility treatments and diagnose causes of infertility
  • Diagnose certain diseases and cancers
  • Identify cell abnormalities
  • Examine blood flow and blood vessels
  • Assist with a treatment
  • Assess mammography findings that are unclear, assess breast lumps, and help guide breast biopsy procedures

If you and your partner would like to know, an ultrasound can also reveal your baby’s gender during pregnancy.

How does an ultrasound work?

With an ultrasound exam, a transducer transmits high-frequency sound waves through your body. 

The sound waves come into contact with tissues, body fluids, and bones before bouncing back like echoes. The transducer receives these echoes and transforms them into images that your provider views as pictures on a screen in real time.

During your pelvic ultrasound, depending on the specific type of ultrasound, your ultrasound specialist either moves the transducer across your abdomen or places the transducer in your vagina.

What is a maternal fetal medicine ultrasound?

Maternal fetal medicine (MFM) specialists have usually received extra training and have extensive experience in the individualized care and testing of complex and high-risk pregnancies.

Different types of maternal fetal medicine ultrasounds are available. Most involve looking more closely at your baby’s face, stomach, heart, spine, kidneys, arms, legs, brain, bladder, hands, feet, genitals, and umbilical cord. 

Your provider might also use ultrasounds to examine your baby’s liver, spleen, lungs, adrenal glands, intestines, and blood flow.

With specialized ultrasounds, your specialist focuses on your baby’s anatomy to identify any irregularities while simultaneously assessing your baby’s environment and growth.

Westchester Women’s Medical Healthcare uses only the most advanced and sophisticated imaging equipment and technology for optimal accuracy, convenience, and safety.
