Specialty Obstetrics of San Diego uses the latest in ultrasound technology to provide patients with the full spectrum of ultrasound services performed in pregnancy.


1st Trimester Screening

First Trimester Screening is a non-invasive evaluation that combines a maternal blood test and an ultrasound of the baby’s neck (nuchal translucency) between 11-14 weeks to identity babies at risk for Down’s syndrome (trisomy 21) and Edward’s syndrome (trisomy 18). Approximately 85% of babies affected by trisomy 21 and 95% of baby with trisomy 18 will be identified by this test. About 5% of normal babies will have a false positive test. A positive test does not mean your baby has trisomy 21 or trisomy 18, but rather that you are a candidate for further testing. Specialty Obstetrics of San Diego providers are certified by the State to perform first trimester screening


2nd Trimester Ultrasound

Our physicians, as specialists in Maternal-Fetal Medicine, are uniquely trained to perform detailed ultrasound examinations of your baby.  We perform high resolution second trimester ultrasounds to detect fetal anomalies.  We also are experts in the use of ultrasound to detect fetal “soft markers” which may increase the risk of Down Syndrome or Trisomy 18 if present.  Thankfully, most ultrasound examinations are normal, reassuring, and a joyful experience for the patient.  We provide patients with pictures of their baby to remember the experience.

The State of California has recently instituted a program to combine first and second trimester screening which has increased the detection of Down’s syndrome to 90-95%.

Diagnostic 4D Ultrasound

Our providers use 4D ultrasound in select cases where this technology has been shown to be of benefit such as the evaluation of the fetal lip, palate, and brain.  As recommended by major medical organizations, we do not offer 4D ultrasound examinations for the sole purpose of a keepsake.

Fetal Echocardiogram

Fetal echocardiography is typically performed between 22-24 weeks gestation. Heart defects affect 1/100 to 1/200 babies and the defects can range from mild to life threatening. Fetal echocardiography can detect 70-80% of the major heart anomalies.
Fetal echocardiography is performed on all pregnant women who’s babies are at increased risk for cardiac defects.  Factors that increase risk include:

•    Mothers with diabetes existing before pregnancy or diagnosed in the first trimester
•    First trimester exposure to medications or agents known to cause birth defects
•    Patients with seizure disorder, even if not on medication
•    Patients with a prior child born with heart defects
•    Patient or husband born with heart defect
•    Patients who’s babies are at risk for genetic problems such as genetic syndromes
•    Suspected fetal arrhythmia or heart defect on previous ultrasound
•    Fetuses with other anomalies detected on previous ultrasound
•    Single umbilical artery
