1 Intradecidual sac sign of an early intrauterine pregnancy, with a hypoechoic saclike structure (arrow) of less than 5 mm located within the thickened, echogenic decidual reaction of the endometrium (arrowhead).

2 Normal early intrauterine gestational sac with separation of the hyperechoic decidual endometrial and gestational sac layers, creating the double decidual sac sign (arrows).

3 Normal 9-week intrauterine pregnancy shows a well-defined embryo (arrows) and yolk sac (arrowhead) with normal separation of the amnion (A) and chorionic (C) sacs.

4 Early failed intrauterine pregnancy with a calcified yolk sac (arrow) and embryonic remnant (arrowhead).

5 Color Doppler ultrasound of an incomplete abortion with increased vascularity, fluid, and echogenic debris (arrows) along the endometrium.

6 Grayscale (A) and Doppler (B) transvaginal ultrasound images of an ectopic (ECT) right adnexal pregnancy seen as a tubal ring separate from the right ovary (OV). There is also a small amount of adjacent particulate free fluid (FF).

8 Pseudogestational sac (arrows) of an ectopic pregnancy with echogenic material consistent with hemorrhage filling the endometrial cavity.

9 Endometrial cavity filled with heterogeneous cystic and solid placental tissue (arrows), which is characteristic of a complete molar pregnancy.
