Twins At 15 Weeks Pregnant Ultrasound
How late can you detect a heartbeat from twin pregnancy with transvaginal ultra sound? If demise of one twin will other twin have issues?
Twin is high risk..:
Generally, embryonic cardiac activity is seen between 5 and 6 menstrual weeks of pregnancy - single or twins or triplets.
If both fetuses share a single placenta (monochorionic, monoamniotic placentation), and if one is demised, the other will likely have problems. A main concern is the effects of twin-twin transfusion. ...Read more
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
????: 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
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

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 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

I Hope Not!: Twins at 7 weeks should be fairly clearly visible on a transvaginal sono. As far as whether or not they might be identical, that is a more difficult question to answer by sono and requires careful analysis of the membranes surrounding fetuses, unless there is a single sac which would only be seen in an identical twins (rare). They can also be in 2 sacs however. ...Read more
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.

Non-invasive prenatal genetic testing is now available. ...Read more
