When can you see the fetal pole on an ultrasound?

The fetal pole is usually identified at ~6.5 weeks with transabdominal ultrasound imaging and at ~6 weeks 2 with transvaginal ultrasound imaging, although it may not be seen until ~9 weeks in some cases. When the fetal pole measures ≥7 mm, a fetal heartbeat should be detected.

What is the fetal pole in early pregnancy?
