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

When are prenatal ultrasounds most accurate for estimating conception? 6 weeks or 10 weeks or 19 weeks?

When are prenatal ultrasounds most accurate for estimating conception? 6 weeks or 10 weeks or 19 weeks?

I vote for: 10 weeks: Usually, prenatal ultrasound scans done while 8-11 weeks pregnant give accurate dating estimates. All dates are estimates, but that doesn't matter much in most cases (an estimate is close enough). If one's cycles are long (more than 31 days) or short (less than 25 days), be sure that is taken into account when making the estimates. ...Read more

Lmp12/23-27 dd 9/19 conception cannot b 12/26 while on my period if i'm 27 weeks 2 days could I have conceived 2 weeks before my lmp?

Lmp12/23-27 dd 9/19 conception cannot b 12/26 while on my period if i'm 27 weeks 2 days could I have conceived 2 weeks before my lmp?

Without looking at..: Without looking at the dates, the usual thing that happens is a woman either gets pregnant 2 weeks before her period starts, or 2 weeks after her period starts (as most cycles are 4 weeks, with ovulation at mid-cycle). If an ultrasound dating scan gave a gestational age estimate, it is very unlikely that the estimate could be 4 weeks off. "conceived 2 wks before my lmp" would mean a 4 week error. ...Read more

Ultrasound measured foetus as 6 weeks 2 days one full week after measuring 5 weeks 6 days (just sac). Heart rate 126 i think miscarriage is likely?

Ultrasound measured foetus as 6 weeks 2 days one full week after measuring 5 weeks 6 days (just sac). Heart rate 126 i think miscarriage is likely?

Not necessarily: The fetus is now off by 4 days and the accuracy of us is about 4 days. Since the other measurement was the sac and this is the fetus, the different measurement may examine it all. The sac and the fetus do not always match exactly. The heart rate is normal so likely all is well. In any event, the next scan will be very helpful. Stay positive as these results to not suggest imminent miscarriage. ...Read more

Unknown LMP but dating scan measured baby at 63.9 at 12 weeks and 5 days. Is 12 weeks and 5 days when i conceived? Edd is 8 february.

Unknown LMP but dating scan measured baby at 63.9 at 12 weeks and 5 days. Is 12 weeks and 5 days when i conceived? Edd is 8 february.

No: Generally ultrasound dating is using the gestational age, which means it is 12 weeks from your last missed period. Generally date of conception is about 2 weeks less than last period. So about 10 weeks ago. ...Read more

I am 6 weeks pregnant according to my LMP edd but ultrasound scan shows only 3 weeks. Is it normal?

GOw/ultrasound but..: At this early stage of pregnancy the ultra-sound is very accurate at predicting due date (edc) +/- 5-7 days . However '3 weeks pregnancy' is still too early to tell much so i would recommend another ultrasound in 3 weeks (@ 6 weeks to document fetal heart tones). The edc needs to be confirmed. Congrats! and good luck. ...Read more

Missed miscarriage I am supposed to be 19 weeks pregnant as of saturday my last period was november 19th i had an ultra sound at 7 weeks and 2 days everything was fine and measuring correctly at 17 weeks they listened to my baby's heart beat with the dopp

Missed miscarriage I am supposed to be 19 weeks pregnant as of saturday my last period was november 19th i had an ultra sound at 7 weeks and 2 days everything was fine and measuring correctly at 17 weeks they listened to my baby's heart beat with the dopp

I : I am sorry that you are going through this stressful experience. Fetal heart beat can usually be heard at 9 weeks in thinner women, and later in heavier women with a doppler (fetal heart monitor), however it can be seen much earlier, up to 6 weeks or sometimes even before, with an ultrasound. An ultrasound is much more accurate at both looking at the baby and measuring the heart rate than just the doppler. ...Read more

Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more
