OB-Sonology
Prenatal ultrasounds and fetal health monitoring.
OB-Sonology Services at Patient First
At Patient First Medical Clinic and Diagnostics Center, we offer in-clinic OB-Sonology services for patients needing detailed pregnancy-related ultrasound scans. These are conducted by licensed OB-Sonologists trained to interpret fetal development, maternal health indicators, and high-risk pregnancy concerns.
What Is OB-Sonology—and How Is It Different from Routine OB-Gyne
OB-Sonology is a specialized field within Obstetrics that focuses on detailed ultrasound imaging to assess the health and development of the fetus and the condition of the mother during pregnancy.
While a general OB-Gyne may perform basic scans, OB-Sonologists provide advanced assessments, often in high-risk or referral cases.
Patients are commonly referred for OB-Sonology when:
A detailed fetal growth scan is needed
There is suspected abnormality in a previous scan
The pregnancy is considered high-risk (e.g., hypertension, gestational diabetes)
Confirmation of fetal age, position, or development is needed
Multiple pregnancies (e.g., twins) require closer monitoring
Specialized Ultrasounds We Offer
OB-Sonology services at Patient First include, but are not limited to:
2D Congenital Anomaly Scan
Biophysical Profile (BPS)
Fetal Growth Monitoring
Transvaginal Sonogram (TVS)
Dating Scan / Early Pregnancy Confirmation
Placental Localization and Amniotic Fluid Index (AFI)
Pelvic or Uterine Ultrasound for gynecologic assessment
All ultrasound procedures are performed in a private, professional setting using accredited equipment.
When to Schedule an OB-Sonology Scan
Your OB-Gyne or general physician may refer you for a sonology scan based on clinical findings or lab results. However, you may also walk in for second opinions or routine fetal assessments, especially during:
First trimester (for dating and viability)
Second trimester (for anomaly scan or gender check)
Third trimester (to assess fetal growth and well-being)
Early and mid-pregnancy scans help ensure that both maternal and fetal health are closely monitored.
