Can Gas Abstract A Fetus Sonogram
Can a fetal doppler detect womb sounds, maternal heart beat, and umbilical cord (abdomen the size of a 26 week pregnancy) with a pseudo pregnancy. ?
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
6 weeks and 3 days pregnant. US showed gestational sac and fetal pole shown, no heart beat. HCG decreased from 17407 to 10943. Is this a problem?
Yes: I am more concerned with the falling HCG than the lack of Fetal heart at 6 wks. If the dates are wrong, the fetal heart beat may not be visible. This can be checked by repeating the U/S in two weeks. Falling HCG is abnormal at this stage of pregnancy. I recommend you have it rechecked and the U/S repeated. The image is of a 6 wk preg. See how small the fetus is. It is easy to miss a heart beat ...Read more
6-7 weeks from LMP: Transvaginal ultrasound can detect fetal heartbeat earlier than transabdominal ultrasound (5-6 weeks after lmp). Transabdominal ultrasound varies a bit more primarily due to differences in maternal size. In general, the fetal heartbeat should be visible transabdominally by 7 weeks from the first day of the last menstrual period. ...Read moreSee 1 more doctor answer
May need to do trans: Vaginal scan, can see a ht beta on transvaginal scan at 6 weeks sometimes definitely by 7 weeks. ...Read more
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
I'm 21 weeks of gestation, how can I know that the fetus is well?
Can dopplar study be reassuring?
Ultrasound: Many moms do find reassurance in US as they can actually see their developing baby moving around and the physician can check anatomy. They aren't required though. Your OB is monitoring your growth and the babies heart rate - two parameters that are followed to see if everything seems to be progressing normally. ...Read more
No: The difference between 8-9 weeks pregnant and 12 weeks pregnant is very different on ultrasound. At this early stage, an ultrasound measurement is accurate to within a few days of how far pregnant you are. ...Read more
Is this normal pregnancy or miscarriage?
single intrauterine gestational sac seen measuring 2.2 cms,corresponding to 6+ weeks
Can the measurements of an 8or9 wk fetus measure "big" and be mistaken for a 12wk fetus? Do fetuses have similar growth patterns at this early stage?
No and Yes: First trimester ultrasounds are very accurate for establishing your due date due the small variation in fetal growth at this stage. ...Read more
Is a small gestational sac in relation to the fetus a sign of a chromosomal abnormality. Fetus 9w sac 7w. Doctor and research have me very worried.
Hard to answer...: At such an early stage, imaging and interpretation is hard. There are associations between size and abnormalities. But it is impossible to look at a minimally smaller size and conclude anything, especially chromosomal disorders. It is best not to worry, but follow this serially and monitor progress. Your OB is the best judge of this and should advice you of intervention if at all needed. ...Read moreSee 1 more doctor answer
11 weeks: or so, but it doesn't have the highest accuracy this early. ...Read more
No.: That is close to an 11 week fetus. Far too large for an 8-9 week gestation. ...Read more
Would an ultrasound of the uterus and a transvaginal ultrasound see a fetus without doing a stomach ultrasound? Just curious
I'm 51/2 weeks and they can't find a gestational sac during ultrasound. Does this mean a miscarriage?
Can weeks be different from LMP to what ultrasound shows? I should be 7 weeks and ultrasound show only a gestational sac at 5.3 wks.
Sono better than lmp: There are 2 possibilities. One is that you conceived later than you thought, perhaps due to late ovulation. The other is that the conception failed very early and has stopped growing. At 7 weeks there should be a distinct embryo and fetal heart visible on vaginal scanning. A repeat scan in 7-10 days will show if the 5.3 week sac is developing normally or not. Good luck. ...Read more
What is the range of accuracy for an 11 week abdominal ultrasound? Possible to mistake an 14-15 weeks fetus for an 11 week fetus? Crl measured 45mm.
Sono reliable: For dating pregnancy, an ultrasound at the stage you define is a very good time to do so. A fetus that demonstrates cardiac activity and appears to be 11 wks by crl is reliably 11 weeks. That's one reason for doing ultrasound. Abdominal ultrasound of the fetus at this stage does have limited accuracy with regard to fetal anatomy, but dating should be quite reliable. ...Read more
