An ultrasound examination uses high-frequency sound waves to create a visual image of fetal structures. Extensive studies to date show no evidence of ill effects or harm to the fetus by these sound waves. Other studies have shown that it is possible to detect many birth defects early in pregnancy that would otherwise go undetected until birth. The ultrasound also allows evaluation of the number of babies, fetal growth, due date confirmation, determination of placental position and other information about the pregnancy that can be useful to you and your doctor.
You do not need to have a full bladder for ultrasounds in our office; however, it is helpful to have your bladder partially full at the beginning of the ultrasound. Obstetrical ultrasounds take approximately 30 minutes to complete. Comprehensive (Level II) scans take approximately one hour.
