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's the most accurate, the CRL or the FL,AC, HC ? Which one gives you the most accurate fetal age ? What are the errors?
All of the above.: I am not an Obstetrician, but as I understand it, no one measurement is "most accurate" for fetal age. That is why all are measured together - some sort of average of all the measurements is the best indicator of gestational age. Every baby is different, & due to genetics some babies will have larger heads for a given age, others will have long legs. So doctors follow growth of all parts over time ...Read more
Pregnancy dating: I assume by you mean a discrepancy in size? A first trimester ultrasound is considered "consistent" with dating by lmp if measurement is within 7 days of the gestational age by lmp. A 1st trimester ultrasound is a more accurate way to date a pregnancy in most cases because due date based on lmp assumes that you had a 28 day cycle and ovulated on day 14. Many woman do not have a 28 day cycle. ...Read moreSee 1 more doctor answer

How important is the date of the last menstrual period in relation to the actual ultrasound dating?
Depends: For an early sono the lmp is less significant since early on, the sono dates are felt to be more accurate. If a patient shows up in the third trimester for her first sono the lmp dates are more important since they are usually a better guess of the actual fetal age. The sono is then used to try to estimate fetal size and growth on subsequent scans. ...Read more

Ultrasound dating.: First trimester ultrasound is by far the most accurate in determining the precise due date (+/- 3-7 days, depending on exactly when it is performed). Second trimester sonograms are less accurate but still helpful in pegging down the due date within +/-7-12 days. Third trimester scans are not very accurate in dating the pregnancy, as growth varies (+/- 14-21 days). Menstrual dating is not very good. ...Read more

Same date : A four day difference is mathematically speaking no difference. You are within the margin of error of a sono machine. A due date simply marks the gestational age if 40 weeks. In this case either date is appropriate. You and your doctor can choose which to go by. Ask your doctor why he or she chose one over the other. ...Read more

It depends: It depends on what was measured and when. Very early, the sac diameter is accurate to ±5 to 7 days. Later, a measurement called the 'Crown-Rump-Length' at 7 to 10 weeks of gestation is the accurate to ±3 days. After 10 weeks, the accuracy of the CRL falls slightly with a margin of error of ±5 days at 10 to 14 weeks. ...Read more
