1.  First Trimester Ultrasound.

A First Trimester Ultrasound is perfomed up to 12 weeks of gestation when the fetus (es) can be  evaluated for size, dates, and viability (heart tone). These images can be obtained  by a transabdominal approach or a transvaginal imaging (prefered by most physicians). The uterus, ovaries, and implantation site can also be evaluated.

2.  2nd/3rd Trimester OB Complete.

In a Second and Third Trimester Ultrasound,  the complete anatomy of the fetus can be evaluated and  measured to determine the gestational age. The placental grade and position can be evaluated as well as the amniotic fluid volume, the fetal position, and the cervical length.

3.  2nd/3rd Trimester OB Follow up.

With this exam, we can evaluate some particular areas of a prior complete exam that were previoualy limited , were abnormal or needed a follow up.  Ex. fetal position, placental position, fetal size and dates, etc.

4.  OB Limited Exam.

This exam is similar to a follow up except that, in this exam,  a specific area or suspected diagnosis would be evaluated.

5. Biophysical Profile.

A Biophysical Profile or best known as (BPP) is performed to evaluate fetal wellbeing.  This evaluation could be pewformed from the 24th  week to the end of the pregnancy. Four parameters will be scored for this test: Fetal Movements, Fetal Tone, Fetal Breathing Movements, and Amniotic Fluid Index.

6. Fetal UA, MCA and Ductus Venosum Doppler.

This is ordered  by physicians to evaluate the blood flow in the umbilical cord, middle cerebral artery and the ductus venosum.  This exam relates to patients with a high risk pregnancies, intra uterine growth restriction, sickle cell anemia, and other abnormal diagnoses.
