16 Week Ultrasound: What to Expect

Ultrasound is a diagnostic instrument used by doctors to visualize muscles, tendons, internal organs, among other things, in order to capture the size, structure or any pathological lesions. It’s used to visualize fetuses during routine and emergency prenatal care, and works as a cyclic sound pressure that only humans can’t hear.

The ultrasound at 16 weeks may strongly support the whole process related to the health and safety of the fetus and the mother, and sheds light on potential negative as well as positive findings.

The ultrasonic waves examine the size and indicate how big is baby at 16 weeks. Average data show that the fetus may be four inches long, and at a healthy weight of over three ounces. A normal heart is supposed to pump twenty-five quarts of blood on a daily basis.

Depending on the development and size of the embryo, the heart images, etc., a miscarriage may be identified via the 16 Weeks Pregnant Ultrasound check. Providing ultrasound examination data that contain the embryo measurements is treated, too, as mandatory to support a possible abortion emergency.

With the help of the ultrasound on the 16th week of pregnancy, you’ll notice the maximum development of the baby. Most of the major organs are completely formed and start to function in the second phase of pregnancy. Eyebrows, fingernails etc. are formed in this trimester. The skin also gets covered with fine hair.

In the middle of the second trimester, the mother can feel the movements of the baby in her womb. In this stage, the mother body is continuously expanding to accommodate the developing baby. By the end of the second trimester, the baby is 11-14 inches lengthwise and weighs around 2.5 pounds.

The ultrasound of the initial anatomy of the fetus, however, during the second trimester falls short of identifying all defects by birth. It is its diagnostic objective that comes to the fore. The general imaging and/or monitoring of the heart requires the prudent approach of the health care provider. The evaluation may focus on possible further testing options. Certain recommendations may integrate the assessment of the status of an artery or other risks or risk factors. That approach may be accompanied by serum testing of the mother or other procedures, aiming at determining a possible genetic abnormality or disease risk.

Examining the fetus in the uterus via the use of ultrasonic waves serves predominantly the diagnostic needs. The ultrasound at 16 weeks may detect a heartbeat or identify a heart defect. As a cardiac anomaly falls within the range of the most frequent concerns, an early scan focuses on the need for a special treatment of the fetus. Through the method, the fluid is analyzed to determine the risk. A careful assessment is needed, however, as an abnormality might be disguised due to the drain system of the fetus sufficiently developed at 16 weeks.
