Getting an early peek at your baby's development is one of the most incredible experiences that new parents will have.
Ultrasounds are performed by your provider or Mayo Clinic Health System's group of diagnostic medical sonographers. You may have one adult accompany you to this appointment. Minors are not allowed.
The following outlines when an ultrasound may be needed:
In the first trimester, ultrasound can be used to help determine birthdate and potential for multiple births.
The second ultrasound occurs between 18 and 22 weeks and typically lasts about 45 minutes. The technologist performing the exam will save multiple images to be reviewed by a radiologist to help evaluate your baby's growth and development. At this point in pregnancy, it is possible to determine your baby's gender. Just let your team know if you would like to be informed or if you would prefer to wait until delivery.
Ultrasounds are not always performed in the third trimester, but may be ordered to help determine the baby's estimated weight, amount of amniotic fluid, location of the placenta, fetal heart rate and well-being, and confirming delivery date range.
