The focus of this course is to educate students on the use of first trimester ultrasound markers to provide pregnant patients with accurate risks of aneuploidies such as Down syndrome as well as other poor pregnancy outcomes. Day 1 lecture emphasizes the nuchal translucency (NT) and includes information about the standardized technique for acquiring accurate NTs, steps to earning and maintaining an NT credential, use of the NT in the CA State Prenatal Screening Program, pearls for optimizing various ultrasound machines to produce the needed images. Day 2 lecture includes additional first trimester ultrasound markers (nasal bone, tricuspid/ductus venosus/uterine artery Doppler) that further refine a woman’s risk for aneuploidy as well as other fetal defects and poor outcomes. Each day consists of a hands-on lab with live patients who are between 11 and 13+6 weeks of pregnancy. Transvaginal scanning is included as needed.
This Course is intended for Physicians, Nurse Practitioners, Nurse Midwives, Physician Assistants, and Sonographers.
