ultrasound tests | new york city
Ultrasound tests can serve a variety of different purposes when it comes to prenatal testing and gynecologic treatment. At our New York City office, we provide a variety of different ultrasound tests performed by our expert technicians. We’ll coordinate with your gynecologist and maternal fetal medicine team to make sure you get accurate results and a comprehensive treatment plan with our high frequency ultrasound tests.
What is High Frequency Ultrasound?
Ultrasound technology uses high frequency sound waves to map out an image of the underlying tissues. Ultrasound transducers can perform at different ultrasound frequencies, and there are some benefits to performing ultrasound tests at high frequencies. This is because higher frequencies have shorter wavelengths, which can be more easily absorbed by the tissues and don’t need to penetrate as deeply. This makes it ideal for superficial tissues and structures in the body versus deeper tissues like musculoskeletal structures.
How is an Ultrasound Test Performed?
Ultrasound tests in New York, NY can be performed with different transducers based on your specific testing plan. For example, the transducer can be placed externally on the abdomen, or internally in the vaginal canal. Each method has its benefits and your OBGYN or maternal fetal medicine specialist will instruct you on which method you can expect. Each will come with specific steps to follow, and you’ll receive these before your ultrasound appointment.
What Types of Ultrasound Tests are Available?
We’re proud to offer the highest standard of care and state of the art ultrasound equipment for imaging in the Manhattan area. Our expert staff can guide you through your unique testing process and provide fast, accurate results. The ultrasounds our team can provide during appointments include:
The nuchal translucency test measures the nuchal fold thickness. This is an area of tissue at the back of an unborn baby’s neck. Measuring this thickness helps assess the risk for Down syndrome and other genetic problems in the baby.
It’s recommended that all pregnant women have an ultrasound to achieve these principal aims:
- To confirm the fetus is alive
- To measure the size of the fetus
- To detect if there are multiple pregnancies
- To assess the placental position
- To assess the amniotic fluid volume
- To review the basic structures of the fetus
- To assess the maternal pelvic structures
How many ultrasound sessions needed during the pregnancy vary by patient and practitioner interpretation of the medical literature, but often occur at least once between 20-22 weeks. A fetal anatomy survey cannot detect all fetal problems and the accuracy of the scan depends on the position of the fetus, the gestation, and maternal build. For larger women with increased body fat, the diagnostic accuracy of an ultrasound may be reduced.
This ultrasound imaging survey determines whether your baby’s growth is normal. Maternal fetal medicine specialists typically recommend it for pregnant women during the third trimester.
A cervical length scan analyzes how long the cervix is and can be used to predict the risk for preterm delivery. The cervical length is most accurately assessed on a transvaginal scan with an empty bladder.
A fetal biophysical profile is a prenatal test used to check on a baby’s well-being. It evaluates the baby’s heart rate, breathing, movements, muscle tone, and amniotic fluid level.
Amniotic Fluid Evaluation with Fetal Position
The sonographer will estimate the amniotic fluid volume by measuring fluid pockets during the ultrasound. The amniotic fluid index (AFI) is measured by dividing the uterus into four imaginary quadrants. The deepest, unobstructed, vertical pocket of fluid is measured in each quadrant in centimeters. The four pocket measurements are then added to calculate the AFI. Normal AFI values range from 5 to 24 cm.
Most babies are positioned headfirst by the end of the third trimester. That doesn’t always happen, though. Ultrasound imaging can confirm the baby’s presentation so that your health care provider can discuss options for delivery.
This is a non-invasive diagnostic exam that produces images that are used to assess organs and structures within the female pelvis. A pelvic ultrasound allows quick visualization of the female pelvic organs and structures including the uterus, cervix, vagina, fallopian tubes, and ovaries.
What Types of Outpatient Procedures Are Available?
We also offer a selection of outpatient procedures and services at our New York clinic using high-frequency guided ultrasound. These include:
Amniocentesis (also called amnio) is a common prenatal test used to diagnose certain birth defects and genetic conditions. Genetic conditions are health conditions and birth defects that are passed on to the baby from the parents, as well as the extended families. Genetic conditions can cause health problems for your baby, so amniocentesis can help us establish a care plan before your baby is born.
Chorionic Villous Sampling
Chorionic villus sampling (CVS) is a prenatal test used to diagnose certain birth defects and genetic abnormalities in your baby. Genetic abnormalities are changes in the genes that are passed down to your baby from you and your partner. These genetic changes can cause health problems for your baby, sometimes resulting in certain chromosomal conditions.
Multifetal Pregnancy Reduction
Sometimes called selective reduction, this option is sometimes indicated when the presence of multiple fetuses makes it less likely that all the fetuses will be born healthy. This is more common when using certain fertility treatments, and a multifetal pregnancy reduction can reduce the risks of complications to your health.
An SIS is a GYN ultrasound where a small amount of sterile saline is placed within your uterus to better evaluate the endometrial lining. Your gynecologist may order this test if you have a history of abnormal or irregular vaginal bleeding, or if your gynecologist suspects that you might have polyps or fibroids within your endometrial cavity. SIS is sometimes performed if you have a history of multiple miscarriages or infertility. It can also be used to help determine if your uterus is shaped normally (i.e. that you do not have uterine malformation).
