Ultrasound Evaluate Fetal Growth
32-36 week scan.: A third trimester sonogram can help evaluate fetal growth if previous sonograms have established the due date with accuracy. Fetal biometry and anatomy is reviewed at each such scan. Many intestinal and urological anomalies can be thus detected, as they only show up in the third trimester. ...Read moreSee 3 more doctor answers
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

What happens if baby drops from fetal growth percentile in 4 weeks but is still within the 10 and 90%? Is that a reason for concern?
No concern: The ultrasound measurements can vary from one test to the next. In the last month or two of pregnancy, ultrasound "guesses" about baby's size and weight can be off by quite a bit. It is not perfect technology. As long as the baby does not drop below the 10th percentile it should be fine. It sounds like you are being followed closely, which is good. Good luck. ...Read more
If there are similar patterns in fetal growth before14 wks, then why would a dr. Say that u could really be11wks or13wks? If u measure 12wk, r u really?
Measurement error: Dating a pregnancy by ultrasound relies on measuring the length of specific structures. There is some variability in the normal range of size of these structures and some variability in the ability of the ultrasound to identify and measure this correctly. Thus there will be error in the "guess" of the age of the pregnancy. In the 2nd trimester, that error is about +/- 2 weeks. ...Read more
There's an app, also: http://www.babycenter.com/pregnancy-week-by-week. It'd be good if all women of child-bearing age took daily Folate (folic acid) supplements, protected themselves from " the flu", planned their pregnancies, knew that 4 standard alcoholic drinks = a binge in women & understood that the fetal brain & spinal cord start forming at 3 weeks & other organs between 3- 10 weeks after conception. ...Read moreSee 1 more doctor answer
MF/placental factors: Maternal-fetal and placental etiologies can all cause fetal growth restriction. Severa fetal syndromes can lead to fgr (e.g. Down, patau, triploidy, edwards, noonan's, digeorge). Multifetal pregnancies are at increased risk for fgr; this can result in fetal demise, fetal brain injury, cerebral palsy or even normal outcomes in non-syndromic cases. Placental infarcts, hypertension, lupus: culprits. ...Read more

6 weeks pregnant & have lost all symptoms. High-risk pregnancy with possible slow fetal growth according to OB. Am I facing the loss of this baby?
Fetal age due to LMP should be 7.2 but ultrasound after spotting showed the gestational age of 6.5 with flicker. normal or can be some growth issue. ?
Can a fetus that shows at the ultrasound 8 weeks can actually be 14 weeks and the ultrasound to show more?
Don't completely: understand the question, but a normal 14 week fetus could never be mistaken for an 8 week gestation. ...Read more
Varies: On transvaginal ultrasound fetal heart activity can be seen as early as 5.5 weeks but more typically after 6 weeks and always after 7 weeks in live pregnancies. In very early fetuses, on trans-abdominal sono early fetal heart visualization is complicated by uterus position, large patient size, and bladder filling. ...Read moreSee 1 more doctor answer
Depends: There are some fetal cardiac arythmias that needs treatment while in utero, but not all of them. It is recommended to discuss this problem with a maternal fetal medicine specialist that will provide all the necessary info. ...Read more
Sounds like: If it was an "echogenic intracardiac focus", this is a "soft" or 'minor' marker for down's syndrome, and in patients who are otherwise "low risk" for genetic defects, it is not felt to indicate an increased risk for ds. But most doctors would offer you a consult to a high risk OB specialist for more testing; or blood work from you that is almost 99% accurate to check for ds, tri13 ;18. Eif may res. ...Read more

Hi I had ultrasound done can see fetal pole and yoke sac but no heatbeat baby is 6 weeks is this normal
I had ultrasound on 01/20/14, with the baby measuring at 4.8 cm, is this accurate for a dating of 11weeks 4 days fetus?
Yes: Average length at this gestational age would be 4.1 to 5.4, so your baby definitely falls within that range. Good luck! ...Read more
Had ultrasound at 8 weeks, showed 3 sacs, 2 empty, 1 with fetus and heartbeat. Is it possible I will be having triplets??
When you have an ultrasound dating scan and they say you are just under 4 weeks have they add 2 weeks or is that how old the fetus is?
Gestational age: Usually we talk in "gestational age" which already adds the 2 weeks. But it would be unusual for them to say you were just under 4 weeks based on an ultrasound. In this case, they would be only able to measure the gestational sac size. If this is true, the ultrasound would usually be repeated in 2.5 more weeks at which time the "fetal pole" with heartbeat should be seen and measured. ...Read more
When i had my transvginal ultrasound at 6 weeks the fetus had heartbeat but at 9 weeks the heartbeat was gone. what could be the cause?
Genetic abnormality: You had an early fetal demise. This is fairly common and most often its a chromosomal (gene) abnormality during early development that is responsible. ...Read more
What constitutes a "strong" fetal heartbeat? Is this referring more to the bpm, or to the visual strength of the heartbeat in ultrasound?
Not: necessarily the bpm, but the subjective visual assessment of the waveform and real time appearance. ...Read more
Fetus measures one week ahead. When i can say that i reach the viability? When baby measures 24 weeks on ultrasound or when i am 24 weeks past LMP?
Older than 26 weeks: Date a pregnancy is not pinpoint accurate . It is only a ballpark figure giving your a date to expect the baby to deliver. Viability of the fetus will depend on how well the fetus develops . Generally the best chance to survive is at term. At 26 weeks and older there is at least a chance ...Read more
How accurate is ultrasound done at 20 weeks for gender determination of fetus. Is obstretics ultrasound with same accuracy. Same question for 22 wks?
Depends.: My rule has always been: don't guess! if the fetus is in a poor position for viewing the genitals then no determination can be made. At 20 weeks, if the genital region is visible there is a very high level of accuracy for gender determination. It all depends on the skill of the person doing the scan. ...Read moreSee 1 more doctor answer
Ultrasound at 7wks 6day shows very small gest.Sac but fetus w/ a good hb measuring 7wk2d. Sac is cloudy. Was told i will miscarry soon. Is there hope?
There's always a: Chance. 12 weeks seems to be a 'magic' crucial stage. Miscarriages are more common before 12 weeks and less common after. Ultrasound is not perfect, and sometimes the cloudy sac is a technical issue with the ultrasound. No test and no doctor can predict the future with 100% accuracy. Sometimes the best advice is to to prepare for the worse, and hope for the best. ...Read moreSee 1 more doctor answer
Had NT ultrasound on nov.20 putting me at 12 weeks 4 days;crl of fetus was 6.2cm.What were possible dates of conception?And how accurate is all of this?
Pretty Accurate: Estimated conception would be around sept. 9. This should be accurate to within less than a week. Relations could have taken place up to about 5 days before conception. Good luck. ...Read more
Safe fetal imaging.: Fetal ultrasound is an amazing and safe imaging method employing the piezoelectric properties of quartz crystals to convert electrical current to mechanical vibrations; this creates ultra-high frequency sound waves that can penetrate inside the pregnant woman's body and bounce off different structures with variable characteristics. A computer then processes the feedback signal to image the fetus! ...Read moreSee 1 more doctor answer
A lot of details.: Fetal gender, anatomy in detail (including brain, heart, spine, kidneys, extremities), amniotic fluid volume, due date estimation within 10 days of actual date, cervical and uterine anomaly detection, placental location and pathology. It is a very cost-effective test for any pregnancy and should be universally performed. ...Read moreSee 1 more doctor answer
Most detailed exam: Maternal-fetal medicine or OB doctors. Sonographers spend long time looking at the heart to ensure that there are 4 chambers, an intact septum between the chambers, normal anatomy of the big vessels of the heart, a regular and normal heart rate, etc. They will also look for abnormalities that can be associated with chromosomal or other problems. Details they see change with fetal age and position. ...Read moreSee 1 more doctor answer
