What does GN 6 mean on an ultrasound?
The nomenclature used to describe fetal growth is based on the estimated fetal weight. The estimated fetal weight (EFW) is an estimated measure of the size of the fetus based on the crown-rump length (CRL) and the estimated date of conception. The EFW is given in standard deviations (SD) that compare the size of the fetus to that of the population.
A nuchal fold (or "NF") is a small crease in the thickened skin of the upper part of the neck. A small growth or collection of fluid underneath the skin in the nuchal area is called a nuchal cyst.
GN 6 is the designation for a nuchal cyst that measures one centimeter or less in diameter.
If your child has a nuchal fold cyst, the ultrasound exam will look at it again in about one to two
What does 6 mean on ultrasounds?
A nuchal translucency (NT) measurement of 3 mm or greater is concerning for Down syndrome. While NT can vary slightly from one exam to the next, an NT of 3 or more is considered high. Other conditions, such as anencephaly or trisomy 18, can also be associated with an increased risk of trisomy 21.
A number that appears on your ultrasound exam is called the gestational age, and it shows how many weeks your baby is. It’s usually based on the first day of your last menstrual period, although your provider may use a different date if your ultrasound is performed earlier in your pregnancy.
What does 6N mean on ultrasound?
A 6n (nodule) is an area of the thyroid gland that appears as a small, solid, lump under the thyroid. Thyroid nodules are not cancerous, but may be. If you have a thyroid nodule, it’s important to have it evaluated by a doctor.
The type of thyroid nodule a person has may indicate whether they need to take thyroid medication or thyroid hormone to prevent thyroid-caused hyperthyroidism. A normal placenta measures between 12-16 millimeters from crown to base. Anything greater than 20 millimeters is considered large. A 6N placenta is bigger than normal, but not large. A 6N placenta is normal and does not cause any problems.
What does N6 mean on an ultrasound test?
Normally, the N (numeric) displayed in the first column is the first number in the report, which refers to the nuchal translucency thickness. So, an N6 is a normal nuchal translucency thickness, which is about 1.5 to 3.5 millimeters. An N5 is thinner than normal, an N4 is thicker, and so on.
If you have an N5 or thicker, you should be evaluated by a medical professional. If you have an N6 result, it simply means that your uterus is normal in size. The number “6” refers to the position of the uterus on the pelvic exam, which is about halfway up the belly.
Having an N6 reading does not indicate that the uterus is cancerous or that you have endometriosis. An ultrasound scan is not an effective test for endometriosis.
What does N6 mean on ultrasound?
The N (or Numeric) designation indicates the nuchal translucence of the fetus. Translucence refers to the clear or bright appearance of the membranes that cover the baby’s head, neck, spine, and arms and hands. The nuchal translucence of the fetus is visible in about 30% of a standard ultrasound exam. The more the membranes look like jelly, the higher the likelihood that the baby will have Down syndrome. If you have an N6 ultrasound rating, you’re a normal sized uterus with a small amount of myometrial tissue. Your uterus is the muscular wall of the womb that thickens during pregnancy to prepare for the growing fetus. The thickness of the myometrium is a measure of a woman’s muscle strength, as well as her risk of miscarriage. The thinner the myometrium, the higher the miscarriage risk.
