The Obstetrical and Gynecological Ultrasound Division is part of the Obstetrics and Gynecology Department. Over 9,000 ultrasounds are performed annually and residents gain hands on experience during dedicated rotations. Reports and images are digitally archived for easy retrieval, case presentation and research. State of the art ultrasound machines are capable of 3-D imaging and processing. The division also performs amniocentesis, chorionic villous sampling and gynecologic needle puncture procedures for ovarian cysts, abscesses and ectopic pregnancies. The ultrasound division is AIUM accredited and has sponsored an annual one day regional conference every year since 1995 that is attended by about 125 participants.
