Heartbeats are best detected with transvaginal ultrasounds early in pregnancy.Ĭoncern typically develops if there is no fetal heart activity in an embryo with a crown-rump length greater than 5mm. The heartbeat may not be detected for reasons that include: tipped uterus, larger abdomen, or inaccurate dating with last menstrual period. Answers to common questions: If an ultrasound is done at 6 to 7 weeks and a heartbeat is not detected, does that mean there is a problem? It is recommended that ultrasound only be used if medically indicated. The long-term effects of repeated ultrasound exposures on the fetus are not fully known. The ultrasound is a noninvasive procedure which, when used properly, has not demonstrated fetal harm. What are the risks and side effects to the mother or baby? Identify uterine and pelvic abnormalities of the mother.Identify hydramnios or oligohydramnios – excessive or reduced levels of amniotic fluid.Weeks 18-20 for congenital malformations.Weeks 13-14 for characteristics of potential Down syndrome.Measure the crown-rump length or gestational age.Ultrasounds are usually combined with other tests, such as triple tests, amniocentesis, or chorionic villus sampling, to validate a diagnosis.Īn ultrasound exam may be performed throughout pregnancy for the following medically-necessary reasons: This is a diagnostic procedure that detect or aid in the detection of abnormalities and conditions related to pregnancy.

Most often used during the early stages of pregnancy. Transvaginal Scans – Specially designed probe transducers are used inside the vagina to generate sonogram images. There are basically seven different exams, but the basic process is the same: Although the terms ultrasound and sonogram are technically different, they are used interchangeably and refer to the same exam.
