Types of Pregnancy Ultrasounds
Women undergo different types of pregnancy ultrasounds
When most women think of ultrasounds, they envision the standard imaging test, but there are several types of pregnancy ultrasounds. Most pregnant women will only have a routine imaging examination, but sometimes our Round Rock obgyns will order a different exam.
Three routine types of pregnancy ultrasounds
Most pregnant women have at least one of three routine types of pregnancy ultrasounds, usually between week 18 and week 22 of pregnancy. They may also have one or more additional ultrasounds as the pregnancy progresses.
- A standard ultrasound is performed using an instrument called a transducer. The technician spreads gel across the woman’s belly and rolls the transducer across the surface to produce a two-dimensional image of the baby.
- A 3-D ultrasound is similar to a standard ultrasound, but the images it produces are three-dimensional.
- Of the many types of pregnancy ultrasounds, a 4-D ultrasound provides the most detailed, four-dimensional images of the baby.
Some women may need a specialized ultrasound
Our Round Rock obgyns sometimes require a different look at the baby, and they may order one of the following specialized ultrasounds.
- A transvaginal ultrasound is performed early in pregnancy when the physician wants a closer look at the baby. During this imaging exam, the transducer is placed in the vagina. A transducer may also be rubbed over the abdomen to obtain an image of the baby.
- An advanced ultrasound is one of the types of pregnancy ultrasounds that is performed when the physician wants to exam a specific part of the baby or the uterus. It is similar to a standard ultrasound.
- A Doppler imaging ultrasound is performed for many reasons, including measuring blood flow to the baby and examining a baby’s growth if it isn’t progressing normally.
- Fetal echocardiography provides the physician with a detailed view of the baby’s heart to check for heart defects.
Our Round Rock obgyns provide comprehensive prenatal care, including all types of pregnancy ultrasounds. A healthy pregnancy is our physicians’ goal. Contact us for an appointment.
