The purpose of ultrasound training for obstetrics and gynecology (OB-GYN) residents is to advance the safe and effective use of transabdominal and transvaginal sonography in reproductive medicine, infertility, gynecologic oncology, urogynecology, normal, and abnormal pregnancy. The purpose of obstetrical ultrasound training is to provide an integrated approach of hands-on ultrasound training, required readings, and web-based lecture series around obstetrics. The creation of the pelvic ultrasound curriculum was a part of a research project, which resulted in multiple national and international presentations and publications. Every year of their postgraduate training, the residents spend 1 month in the ultrasound clinic, working through various cases to build technical skills in performing OB-GYN ultrasounds. The training begins with a review of the institution-specific online modules, followed by weekly rotation/hands-on training sessions and periodic ultrasound simulations. Throughout the 4 years of training the resident spends designated time in the ultrasound clinic as well as gain hands-on training on inpatient antepartum patients. Comprehensive training allows residents to perform a well-structured ultrasound examination, write a structured report and graduate with competency in OB-GYN ultrasound. It is designed to help them develop the fundamental knowledge, theoretical background, and mastery of skills of effective diagnostic ultrasound that can be incorporated in their clinical practice postresidency.
