3-032, 3-05d. [ edit on Wikidata] Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb). The procedure is a standard part of prenatal care in many countries, as it can provide a ...
Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis. Fundal height, when expressed in centimeters, roughly corresponds to gestational age in weeks between 16 and 36 ...
Anomaly scan. The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care. [1] The function of the ultrasound is to measure the fetus so that growth ...
Biophysical profile. A biophysical profile ( BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [1] with the score being termed Manning's score. [2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications. The "modified biophysical profile" consists of the NST and ...
Amniotic fluid index ( AFI) is a quantitative estimate of amniotic fluid [1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [1] AFI is the score (expressed in centimetres) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus. To determine the AFI, doctors may use a ...
Dilation and evacuation. Dilation and evacuation ( D&E) or dilatation and evacuation (British English) is the dilation of the cervix and surgical evacuation of the uterus (potentially including the fetus, placenta and other tissue) after the first trimester of pregnancy.

Obstetrics, pediatrics. Large for gestational age ( LGA) is a term used to describe infants that are born with an abnormally high weight, specifically in the 90th percentile or above, compared to other babies of the same developmental age. [1] [2] [3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute ...
There is an 8.1% incidence of low birth weight in developed countries, and 6–30% in developing countries. Much of this can be attributed to the health of the mother during pregnancy. One third of babies born with a low birth weight are also small for gestational age.
