Ultrasound in Obstetrics & Gynecology Q&A
An obstetrics and gynecologic (OB-GYN) ultrasound is a type of imaging that employs high-frequency sound waves to create an interior image of a woman’s bladder, uterus, fallopian tubes, cervix, and ovaries that is displayed on a computer screen for physicians and patients to watch. At Women’s Health Consulting, our board-certified professional, Dr. Wendy Goodall McDonald, MD, and her team provide a unique combination of expertise and patient-centered treatment for women of all ages.

Ultrasound in obstetrics and gynecology is a non-invasive diagnostic tool that uses high-frequency sound waves to produce images of the female reproductive system, including the uterus, ovaries, and fetus during pregnancy. It can be used to confirm pregnancy, determine the due date, monitor fetal growth and development, detect multiple pregnancies, and identify potential problems such as placental issues or structural abnormalities in the fetus. Ultrasound is considered a safe and reliable method for monitoring pregnancy.
Obstetric ultrasound scanning is primarily used for the following purposes:
● Confirming pregnancy and determining the due date – Ultrasound can detect a pregnancy as early as six weeks and determine the fetus’s gestational age, which helps to establish the due date.
● In monitoring fetal growth and development, ultrasound can be used to check the fetus’s size, position, and movements, as well as to check for any structural abnormalities.
● Detecting multiple pregnancies – Ultrasound can detect the presence of more than one fetus in pregnancy.
● Identifying potential problems – Ultrasound can detect potential problems with the placenta, such as placental insufficiency or placenta previa, as well as structural abnormalities in the fetus.
● Amniotic fluid volume assessment – Ultrasound can assess the amount of amniotic fluid around the fetus and can detect any problems related to the amount of fluid.
● Assessing cervix length and position in high-risk pregnancies – Ultrasound can assess the length and position of the cervix which can indicate the risk of preterm labor.
Ultrasound in gynecology is used to evaluate the female reproductive organs, including the uterus, ovaries, and fallopian tubes. It can be used to diagnose and monitor various conditions, such as:
● Ovarian cysts – Ultrasound can detect and monitor cysts on the ovaries and determine if they are functional or potentially cancerous.
● Uterine fibroids – Ultrasound can detect and monitor non-cancerous growths in the uterus, known as fibroids.
● Endometriosis – Ultrasound can detect the presence of endometriosis, a condition where the lining of the uterus grows outside of it.
● Polycystic ovary syndrome (PCOS) – Ultrasound can detect the presence of multiple small cysts on the ovaries, a symptom of PCOS.
● Infertility – Ultrasound can evaluate the uterus and ovaries to check for problems that may be causing infertility, such as endometrial polyps, fibroids, or blocked fallopian tubes.
● Ectopic pregnancy – Ultrasound can detect if a pregnancy is developing outside of the uterus, which is a life-threatening condition.
● Ovarian, uterine, and cervical cancer screening – Ultrasound can be used as a screening tool for these types of cancer in conjunction with other diagnostic methods.
In summary, ultrasound in gynecology is an essential tool for evaluating and monitoring various reproductive health conditions, including identifying potential issues early on and providing important information for diagnosis and treatment.
There are several types of ultrasound, each with specific uses and applications. The main types of ultrasound include:
● Transabdominal ultrasound – This type of ultrasound uses a transducer (probe) that is placed on the skin of the abdomen to produce images of the internal organs, such as the uterus and ovaries. This is the most common type of ultrasound used in obstetrics and gynecology.
● Transvaginal ultrasound – This type of ultrasound uses a transducer inserted into the vagina to produce images of the pelvic organs, such as the uterus and ovaries. It is used to get a closer view of these organs and is often used to evaluate early pregnancy or to check for problems such as fibroids or cysts.
● Doppler ultrasound – This type of ultrasound uses sound waves to create images of blood flow in the vessels, such as the placenta, umbilical cord, and fetal blood vessels. It can be used to evaluate the health and well-being of the fetus during pregnancy.
● 3D and 4D ultrasound – These types of ultrasound use special technology to create 3-dimensional or 4-dimensional images of the fetus, allowing for a detailed view of the baby’s face, hands, and feet.
In summary, the choice of ultrasound depends on the specific condition and the part of the body being examined. Each type of ultrasound has its own advantages and limitations, and the radiologist will choose the best method for the specific situation.
