A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
Beyond the diagnosis of early multiple pregnancy, ultrasound scan is more than for care, a repeat scan in 3–4 weeks can be helpful to determine pregnancy dating .

Halfway through your pregnancy, you will experience one of my favorite parts of pregnancy: the anatomy scan. The anatomy scan is a level 2 ultrasound, which is typically performed between 18 and 22 weeks. Other than finding out the sex of your baby if you want to know , the ultrasound technician will be taking many measurements of your baby. Since the technician will be concentrating on the screen, they may or may not talk you through the examination.
The technician will be assessing the fluid-filled spaces inside the brain and the shape of the cerebellum, which is in the back of the brain. He or she will also be able to identify if any cysts are in the choroid plexus, which is a tissue in the brain that produces cerebrospinal fluid. Fetal cysts may indicate an increased risk for a chromosome abnormality; however, the majority of these cysts disappear by the 28th week of pregnancy with no effect on the baby.
Depending on the positioning of your baby, the technician may or may not be able to detect if your baby has a cleft lip. Rarely are they able to detect if there is a cleft of the palate.

How accurate is your baby’s due date? What to know about when you’ll go into labor

A beautiful, supremely talented young friend of our family recently fell victim to a terrible medical mistake. Newly married, she was having some pelvic pain and bleeding, and the doctor who saw her diagnosed a probable ectopic pregnancy — an embryo that develops outside the womb. Concerned that such pregnancies can turn life-threatening, the doctor prescribed the standard treatment: methotrexate, a drug used for chemotherapy and to help induce abortions. When our friend returned to be checked a few days later, the imaging revealed that in fact, the pregnancy had not been ectopic; it was in place, in her uterus.
But because she had taken the methotrexate, a known cause of birth defects, her pregnancy was doomed. She soon miscarried. What may have been a perfectly healthy pregnancy had been ended by well-meant medical treatment. I assumed her horrifying case was an exceedingly rare medical fluke — until now. A paper just out in the prestigious New England Journal of Medicine shows that such misdiagnosed pregnancies are part of a pattern — a pattern that needs to be changed.
When I told our friend’s story to the paper’s lead author, Dr. Peter Doubilet, he responded that he knows of “dozens and dozens and dozens of similar cases that have come to lawsuits, and that’s probably the tip of the iceberg. The New England Journal of Medicine paper stems from a panel of international experts who resolved to change medical practice to stop such misdiagnoses.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record.
Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.
For instance, the EDD for a pregnancy that resulted from in vitro fertilization should be assigned using the age of the embryo and the date of transfer.
Can your pregnancy scan give the wrong due date?
A first trimester early pregnancy and dating ultrasound is an examination you have during the first 13 weeks of pregnancy. Due to the size of the developing structures and embryo, it is uncommon to perform an ultrasound before 5 weeks gestation 5 weeks after the start of your last menstrual period. Ultrasound is not consistently able to confirm viability and fetal heart activity prior to 6 weeks gestation, so unless there is an urgent need to have an early pregnancy and dating scan earlier most of these ultrasounds are performed after 6 weeks and ideally at 8 weeks for dating purposes.
Urgent cases may still be performed earlier, please discuss this with your referring doctor. Your ultrasound may be performed transabdominally or transvaginally. Transvaginal ultrasound involves placing a thin transducer slightly thicker than a tampon into the vagina.

Throughout my pregnancy , I’ve received two different due dates — one came from my very first ultrasound, when my baby was barely the size of a blueberry, the date that was then subsequently stamped on my record as “the” due date. But then there was a second date, the one that showed up on my next couple of ultrasound scans. This date was a few days earlier.
It’s also the date that I prefer, not only because I’m now 38 weeks pregnant and ready to get this baby out, but because it matched the date I’d calculated on my own using information I looked up. And how much does it really matter? After all, as many moms know, due dates are just educated guesses.
