Ultrasound Pictures Of Hidden Twins
Can a vanishing twin actually be hidden? I am 35 have and have 10 living children, 4 miscarriages. 6 week sonogram clearly showed 1 baby. 8 week sonogram showed 1 baby with heartbeat and another sac partially hidden behind baby.
It definitely wasn't eas
Yes: It sounds like a retained dead twin that was small and not so much hidden, but difficult to see. This does not happen often, but it definitely can happen... ...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
No reliable way: Ultrasound is the only way to "see" what is in the uterus. ...Read more
Yes : Ultrasound is the only reliable and safe way. Other than waiting for delivery. While Xray would show it carries unnecessary risk. ...Read more
Is it possible that the ultrasound technician could not see a triplet hiding behind twins at 11 weeks 3 days?
Yes: Depending on how thorough the study & the training of the tech, missing a fetus is possible. Regular US is a 2 dimensional study and you only see what your probe lights up. ...Read more
At 12 weeks scan the ultrasound technician saw that the baby has penetrated the empty sac of the vanishing twin.how can this be?
What is visible in an ultrasound within the first ten days after conception? Can twins be seen on ultrasound at 20,days after conception?
Gestational sac only: You can only see the gestational sac and very little else except a "dot" inside the sac on ultrasound. ...Read more
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
Hi I had an ultrasound and baby measured 6 weeks 5 days and heartbeat was 152.one week later measured 8 weeks 4 days and heartbeat 171. Twins?
Unlikely: If you got an ultrasound they would have been able to see both fetuses if you were having twins. ...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
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
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
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. Ask your md what the size difference means in your case. ...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
At 4 weeks 4 days my hCG was 3, 900. 40 hours later it was 7, 261. My ultrasound isn't until tomorrow, I'll be 5w4d. Is that high & could it be twins?
There is considerable variability in HCG levels. Ultrasound exam would be better at detecting twins. See this site and discuss the matter with your doctor.

I got the ultrasound done the doctor said it's a twin but I am worried later on if it become multiple?
What do you suggest if my child brought home an ultrasound with 2 gestational sac diameter measurements does that mean its twins?
Not necessarily.: The gestational sac should be measured in three different planes to determine mean sac diameter, so there may be multiple pictures of the same gestational sac with different measurements. ...Read more
Over 35, curious, what obvious symptoms would be indicative of a twin preg? How early can one assume so (aside from the usual ultrasound/blood test?)
