Meet Our Faculty

The Division of Ultrasound is a unique obstetric and gynecologic ultrasound service providing dedicated ultrasound services to the women of Western Pennsylvania by specially trained Obstetrician/Gynecologists who merge clinical experience with diagnostic ultrasound expertise. Established in 1982, the Division is one of only a few dedicated Ob/Gyn ultrasound services in the United States, performing over 100,000 exams yearly. The division was among the first ultrasound facilities to be accredited by the American Institute of Ultrasound in Medicine for obstetrical and gynecological ultrasound.

Members of the division are recognized locally and nationally for their expertise in obstetric and gynecologic sonography. The Division has established itself as a benchmark for expert ultrasound evaluation in Obstetrics and Gynecology. Hence, patients with complicated or abnormal ultrasound examinations are frequently referred for consultation.

The division provides expert imaging evaluation for women in all areas of Ob/Gyn ultrasound which include:


  • Pregnancy dating
  • First trimester screening
  • Anatomic survey
  • Assessment of Fetal Anomalies
  • Evaluation of cervical length
  • 3- and 4-dimensional imaging of fetal finding
  • Assessment for fetal anemia
  • Monitoring of fetal growth
  • Biophysical profile testing

The division monitors fetal growth using customized growth charts which are based on our experience monitoring fetal growth and customized to the patient’s own characteristics. This provides an individualized assessment of the fetal size, leading to a more accurate diagnosis of fetal growth restriction.

The division evaluates a large number of patients referred with fetal anomalies. Our identification of fetal anomalies is above the internationally recognized detection rates.


  • Complete pelvic ultrasound
  • Assessment of pelvic masses
  • Detection of ectopic pregnancy
  • Assessment of pelvic pain
  • Evaluation of congenital uterine anomalies
  • Sonohysterogram
  • Infertility evaluation
  • Pelvic floor imaging
  • Evaluation of pelvic floor mesh

The division collaborates with the Division of Pediatric & Fetal Cardiology of the Children’s Hospital of Pittsburgh in the diagnosis and follow up of fetal congenital heart disease. We also collaborate with the Division of Maternal Fetal Medicine in the care and evaluation of patients with high risk pregnancy. The division works closely with the Division of Genetics in the diagnosis of fetal genetic disorders as well as aneuploidy screening. The Center for Advanced Fetal Diagnostics is our dedicated service for the care and treatment of patients with fetal anomalies. The division is a critical part of that service, providing the imaging expertise for patients referred for evaluation of fetal anomalies. The Center for Innovative Fetal Intervention works closely with the division in the evaluation, care and treatment of patient’s referred for fetal surgery. The division evaluates the fetal anomaly and provides intraoperative guidance for all surgical procedures.

The division has long and rigorous education program, providing education and training to sonography students, medical students, residents, fellows, nurse midwives and many regional sonographers seeking additional training in Ob/Gyn ultrasound. Many members of the division are actively involved in setting international ultrasound standards through appointment to committees of the American Institute of Ultrasound in Medicine and have active research in the areas of pelvic floor imaging, fetal growth, ultrasound education and fetal surgery.
