Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Saw twins on my ultrasound but one is bigger than the other. Is that a problem?

Depends: In general it is common for one twin to be slightly larger than the other. In some rare cases it can be a problem (usually with identical not fraternal twin) usually serial sonograms will be done to evaluate the growth of both twins.

Had ultrasound at 6. 2 weeks one had heartbeat 122. Dr said was a twin other sac in ultrasound will I expel it empty sac or does it go away?

Dissolves: Commonly twin gestation turns into single one due to loss of one fetus. As long as this happens early, there is usually no consequences for the remaining fetus. The other one is reabsorbed. Usually this happens for a good reason, and may mean one is not healthy. You could not have prevented it or caused it either. Get followup U/S to make sure you baby is growing well inside you. Best wishes!! ...Read more

Ultrasound shows one IVF twin 4 days behind 9 week scan. Both had strong heart beats. When to worry?

Ultrasound shows one IVF twin 4 days behind 9 week scan. Both had strong heart beats. When to worry?

Not to worry.: I can tell this is a highly desired and anticipated pregnancy and offer you my congratulation on the success thus far. As you know, things can still go wrong as this is a very high-risk pregnancy, so see a maternal-fetal medicine specialist as soon as possible and get information on twin-to-twin-transfusion syndrome and genetic counseling. Non-invasive prenatal genetic testing is now available. ...Read more

Just curious, is an ultrasound the only way to determine if your having twins? Can ob feel more than one when doing regular measurements of belly?

Just curious, is an ultrasound the only way to determine if your having twins? Can ob feel more than one when doing regular measurements of belly?

Ultrasound is best: In this age of technology, Ob/Gyns rely on ultrasound to know if you are having twins. Measurements of your abdomen might provide a hint if you are growing faster than expected but there are also other reasons you might be growing fast besides twins. Farther along in your pregnancy, it is sometimes possible to feel both babys but this is not usually relied on for a definite answer. ...Read more

Just had an ultrasound at 6wks/2dys twin sacs very close together. I've a very tilted uterus. A yolk sac was seen in one but no fetal pole/hb. Viable?

Twin sacs: You will need to have a few more scans over the coming weeks. It is possible that it was too early to see the fetus/heartbeat of both or either twin. Further scans will help see whether it is a miscarriage or not. It is not uncommon to see twin sacs early, but only one living baby later on. One twin can not develop (it dies and is resorbed) while the second twin does well with no problem at all. ...Read more

6 week ultra sound showed heart beat in one sac and yolk in the other. Is this normal for naturally conceived twins?

6 week ultra sound showed heart beat in one sac and yolk in the other. Is this normal for naturally conceived twins?

Septate uterus?: Was there really a second sac, or was it the same sac wrapped around a uterine septum? It is not impossible to have dichorionic twins missed before 6 weeks, but one has to consider all possibilities. Another scenario: vanishing twin syndrome or large subchorionic hematoma. Serial ultrasounds by an expert diagnostician will be required to tell the final diagnosis. Take Folic Acid 1-5 mg daily! ...Read more

Is a high def ultrasound common with twins?

????: Don't quite know what you mean. All our fetal sonos are done with the highest possible definition. There are a few more things we evaluate with twins such as the number of placentas and the sac anatomy. Or as we are fond of saying, "twice the work for the same fee! ". ...Read more

Can both of the twins be seen in detail with an ultrasound?

Usually: Depending on the position of the twins, the sonographer it is usually, but not always, possible to image both twins in detail and determine gender, whether they are monochorionic or dichorinonic, and to visualize their umbilical cords. However, this depends on their current gestational age. Optimal images may take more than one visit for an ultrasonogram. ...Read more

What is the definition or description of: ultrasound to evaluate twins?

Prenatal study: This imaging study is ordered by the doctor to have an idea of the fetus's anatomy, size, gestational age, position of the placenta, amount of amniotic fluid and overall well-being. In the case of twins, you can also compare their sizes and growth. Assessing two babies in utero by ultrasound can be more technically difficult than assessing one because one twin can hide parts of the other. ...Read more

What is the lowest number of days to be able to identify twins on an ultrasound AFTER CONCEPTION date, thankyou?

What is the lowest number of days to be able to identify twins on an ultrasound AFTER CONCEPTION date, thankyou?

4-5 weeks, depends.: It depends on what type of twins (monozygotic / identical or dizygotic / fraternal) & where the implantation occurs, so there's no hard-and-fast rule. I've heard of twins being seen at 5 weeks based on two different heart beats heard on US. It can be seen as soon as 4 weeks if they are separated far enough for US to see. Either way, don't fret; accept congratulations & best wishes to you & partner ...Read more

At 12 weeks the ultrasound technician saw that my fetus has penetrated the empty sac of the vanishing twin. How could this be?

Good question: I am not sure what the ultrasound technician may have meant if he/she really stated the surviving fetus has penetrated the empty sac of the vanishing twin. If he/she is implying that the membranes of the vanishing twin are somehow wrapping around the surviving fetus, then this is a situation that you would want to have clarified by a Maternal Fetal Medicine specialist. Discuss a referral. ...Read more
