Empty sac,no beat: Miscarriage on ultrasound is determined if a pregnancy sac is evident but no fetal pole is seen or there is a fetal pole but no fetal heart rate is seen. Absence of fetal pole, could be due to the pregnancy being extremely early, then a follow up ultrasound is advised in 1-2 weeks. At all times unless an intrauterine viable fetus is detected, an ectopic pregnancy is in the differential diagnosis.

No fetus, &....: If a fetus of the expected size is not present, if a fetus with absent heart activity is seen then there has been a miscarriage (spontaneous abortion) or fetal demise (death).
