Division of Obstetric & Gynecologic Ultrasound

In the Division of Obstetric and Gynecologic Ultrasound, part of the Department of Obstetrics and Gynecology at NYU Langone Health, we use sonography to identify potential obstetric, medical, or fetal problems as early as possible, and to provide clinically relevant diagnoses of gynecologic diseases. This clinical mission enriches the education of our medical students, residents, and fellows and enhances research in obstetrics, gynecology, and oncology.

Our trainees rotate through NYU Langone’s Ultrasound Unit—OB/GYN, a diagnostic referral center featuring advanced sonographic technology that enables expert evaluation of our gynecologic and gynecologic oncology patients.

In addition, our clinical research projects are led by Ilan E. Timor, MD, division director and an internationally recognized expert in the field. He has published 10 books on obstetric and gynecologic ultrasound—notably, Ultrasound in Gynecology translated into three languages and Ultrasonography of the Prenatal Brain, which has three editions and has also been translated into three languages. The fourth edition is now underway.

Dr. Timor also sits on the Society for Maternal-Fetal Medicine task force on placental adherence disorders. He is working with the American Institute of Ultrasound in Medicine and the Society for Maternal-Fetal Medicine task force to develop recommendations on what structures to scan for during the first trimester of pregnancy to better counsel women with various fetal and maternal disorders.

Our Role in Education

Our division works closely with the department’s medical students and residents to guide them through the latest medical and technological advances in ultrasound.

Training for Medical Students

During a six-week clerkship in obstetrics and gynecology, students at NYU Grossman School of Medicine shadow division clinicians as they see patients on the Ultrasound Unit—OB/GYN.

Training for Residents

Second-year residents take turns completing a five-week rotation in the division. Each week, the resident spends three and a half days on the Ultrasound Unit—OB/GYN and one day at NYC Health + Hospitals/Bellevue, receiving hands-on training in transvaginal ultrasonography and fetal imaging. Residents also evaluate the scans from other sonographers in the division.

Dr. Timor lectures residents on the latest developments in the field and is readily available to answer any patient care questions that arise. Residents may also evaluate ultrasound equipment under development by medical device companies to assess fetal head and brain measurements.

Our Role in Research

The division’s research efforts have advanced the field of obstetric and gynecologic ultrasound. Dr. Timor’s own investigations have led to the evidence-based foundation for the clinical use of transvaginal ultrasound in obstetrics as well as in gynecology. We’re currently applying our research to the sonographic workup of complicated ovarian scans using guidelines from the International Ovarian Tumor Analysis group, of which Dr. Timor is an active member.

Prior research conducted within the division includes assessing the use of a cervical ripening double balloon catheter under ultrasound guidance as a treatment for cervical and cesarean scar pregnancy; using transvaginal ultrasound to assess whether the position of the uterus changes after cesarean delivery; diagnosing first-trimester invasive placenta via ultrasound in high-risk women; and determining the ultrasound characteristics of endometriosis and borderline ovarian tumors during pregnancy.

Our Role in Patient Care

The Ultrasound Unit—OB/GYN is a diagnostic referral center staffed by highly trained sonographers who provide women with advanced fetal imaging and transvaginal ultrasound to detect of gynecologic diseases such as ovarian cancer and endometriosis. We also conduct early evaluation and treatment of cesarean scar pregnancy, a precursor of placenta accreta disorders.

Each of our sonographers is accredited by the Accreditation Commission of the American Institute of Ultrasound in Medicine. Dr. Timor receives referrals from the tristate area and beyond.

Our Faculty

Our division faculty are highly skilled in the performance of obstetric and gynecologic ultrasound.
