PSN Diagnostic provides a full range of obstetrical ultrasound services in a relaxed, professional setting. Our high-quality services conform to the most stringent national and international standards. They allow the parents and the doctor to monitor the baby’s development with confidence from conception to birth.
Ultrasound dating and fetal viability
A fetal ultrasound during the first trimester provides a better assessment of gestational age, and therefore, a more precise delivery date. The process involves taking measurements and comparing the findings with gestational age based on the date of your last period and the presumed ovulation date. Generally speaking, the earlier the dating ultrasound is performed, the more accurate it is. The physician may also have concerns about the health of the fetus early in pregnancy and seek reassurance through an ultrasound that your pregnancy is evolving normally. This generally entails locating the fetus within the uterus and measuring its heartbeat. Finally, first trimester ultrasounds are used to identify and characterize multiple pregnancies. Service fee: $150.
Prenatal screening for Down syndrome and preeclampsia
Between 11 and 14 weeks of pregnancy, an ultrasound in combination with a maternal blood test is an effective, non-invasive way to establish the level of risk of chromosomal abnormalities in your fetus, notably: trisomy 21 (Down syndrome), trisomy 13 (Patau syndrome), and trisomy 18 (Edwards syndrome). The ultrasound component includes measuring the accumulation of fluid under the skin behind the neck (nuchal translucency), the nasal bone and sometimes the facial angle of the fetus. Along with the ultrasound, the maternal serum is analyzed for concentrations of two specific proteins i.e. free beta human chorionic gonadotropin (free ß-hCG) and pregnancy-associated plasma protein-A (PAPP-A). Taken together, these ultrasound and biochemical markers result in a screening detection rate for Down syndrome of 90%-95%. This ultrasound session can also be used to measure the pulsatility of the arteries in the uterus for early detection of the risk of the mother developing preeclampsia. Service fee: $380 (includes ultrasound and blood test).
Fetal anatomy survey scan
The ultrasound assessment of fetal anatomy is generally performed between the 18th and 22nd week of pregnancy when the fetus is large enough to provide for an accurate assessment. Growth and development of the fetus are also monitored through a series of measurements such as head diameter and circumference, abdominal circumference as well as femur and humerus lengths. We scan for congenital malformations and check the development of certain organs. Service fee: $190
Uterus cervical length for pre-mature labour screening and 3D+ parental reassurance
A risk calculation for preterm labour can be made based on a measurement of the mother’s cervix between 20 and 24 weeks of pregnancy. The doctor can use this risk assessment to decide if other tests are warranted and to prepare for preventative treatment such as labour suppressing medications. Service fee: $190
Limited assessment and 3D+ parental reassurance
Performed between 24 and 32 weeks, the limited assessment and 3D+ parental reassurance ultrasound allows parents to view their baby’s activities in 3D, playing a reassuring role and strengthening bonds with the newest family member. The session also includes a limited assessment of fetal well-being with a report to the referring physician on heart rate, fetal growth and position, placental position and the quantity of amniotic fluid. Service fee: $190.00.
Placenta position, growth and position of the fetus, and 3D+ parental reassurance
A final, pre-birth scan can be performed at 32 weeks or later. Generally, the referring physician asks for a further assessment of fetal growth and well-being as well as information on the position of both the baby and the placenta. Service fee: $190.00.
