At Metro Central Ultrasound, we provide obstetrical ultrasounds in a comfortable, welcoming environment, to women is various stages of their pregnancies. There four main types of pregnancy ultrasounds typically requisitioned by obstetricians: Dating, Nuchal Translucency, Anatomy, Growth/BPP.
This early pregnancy ultrasound is the first look at the fetus and helps to pinpoint the due date in conjunction with the patient’s reported LMP.
This prenatal ultrasound (also referred to as the NT scan) is a non-invasive procedure performed between the 11 and 14th week, in order to assess your baby’s risk of having chromosomal abnormalities. It measures the translucent space in the tissue at the back of your baby’s neck.
The Anatomy scan is a second trimester fetal ultrasound, usually performed between weeks 18 – 22. This prenatal ultrasound is typically the one that new parents look most forward to. The baby is measured from head to bottom, around his or her tummy and head. Additionally, your ultrasound technician will look at the four chambers of the baby’s heart, along with the kidneys, bladder, stomach, brain, spine, and sex organs. If you wish, you may also learn the baby’s sex during this ultrasound.
The growth scan and biophysical profile (BPP) is an obstetrical ultrasound that can ben requisitioned by a doctor during a woman’s third trimester. It can be ordered when a mother is going passed her due date, or to assess the size of a baby who seems to be measuring significantly larger than expected. However, this pregnancy ultrasound it most often done as a precaution after problems in a previous pregnancy or because of high risk factors such as previous pregnancy loss in the second half of pregnancy, high blood pressure, diabetes, intrauterine growth retardation (IUGR).
Prenatal ultrasounds conducted between 11 and 40 weeks do not require any preparation. And do not require that you have a full bladder. Ultrasounds conducted prior to 11 weeks require you drink between 250 ml – 750 ml of water one hour prior to your scheduled appointment, and do not urinate. This is essential, because it allows us to get a clear look at both the fetus and your reproductive organs.
When you come in for your ultrasound, a trained MCU technician will begin by applying a special gel to your abdomen. This gel is essential to help the sound waves travel smoothly. They will then use a handheld wand called a transducer over your abdomen, which sends high frequency sound waves into your body and back to the transducer. These sound waves are then turned into images that can be analyzed by a medical professional. Measurements may also be taken. For your comfort and convenience, images of your baby will be viewed on a flat screen TV for you and your partner.
Early on in your pregnancy, you may also be given a transvaginal ultrasound, in order for the technician to get a clearer picture of the fetus. For this procedure, a small ultrasound probe will be inserted into the vagina to capture more detailed images.
