Small embryo and yolk sac within an intrauterine gestational sac (A) Small embryo and yolk sac within an intrauterine gestational sac (A). The 5-mm embryo is positioned along the right side of the yolk sac in this image and cardiac pulsations were visible during real-time sonography. Transvaginal image at 7.5 MHz (courtesy of James Mateer, MD). Embryonic pole is separated from the yolk sac and measures 6 weeks ± 6 days via crown-rump length (B). Transabdominal longitudinal view with empty bladder. (Courtesy of Hennepin County Medical Center) Source: Chapter 14.
