Objectives : The purpose of this study was to determine the accuracy of sonographer predictions of fetal gender during routine ultrasounds. Primarily, the study sought to investigate the accuracy of predictions made in the first trimester, as requests from parents wanting to know the gender of their fetus at this early scan are becoming increasingly common. Second and third trimester fetuses were included in the study to confirm the accuracy of later predictions. In addition, the mother’s decision to know the gender was recorded to determine the prevalence of women wanting prenatal predictions. Methods : A prospective, cross sectional study was conducted in a specialist private obstetric practice in the Illawarra, NSW. A total of fetuses across three trimesters were examined collectively by seven sonographers. Fetal gender was predicted using the sagittal plane only in the first trimester and either the sagittal or transverse plane in later trimesters. Phenotypic gender confirmation was obtained from hospital records or direct telephone contact with women postnatally.
Ultrasound baby scans in pregnancy
This scan is carried out from 11 weeks to 13 weeks and six days. The scan is usually performed transabdominally but in a few cases it may be necessary to do the examination transvaginally. If you want to visit your own FMF page please click here.
It may also be offered after 11 or 12 weeks if a trans-abdominal scan doesn’t whereas waiting a week or 10 days will make the findings much clearer. to estimate the delivery date and; to check whether there is one baby, or twins or more.
The nuchal translucency NT refers to the pocket of fluid at the back of the fetal neck. The measurement of the nuchal translucency is part of the combined screening test for trisomy 21 and trisomy 18, called enhanced First Trimester Screen eFTS. An increased NT measurement increases the chance for other chromosome differences, additional genetic conditions, and can also be helpful to predict structural differences that might be more obvious later in pregnancy such as a heart defect.
At the time of the NT ultrasound, the sonographer or physician who does the scan can also accurately predict your due date, determine how many babies you are carrying and examine the early basic structural development of the fetus. Examples of circumstances when this may be applicable are: declining to have prenatal screening for trisomy 21 and trisomy 18, Non-invasive Prenatal Testing NIPT has already been initiated, or the pregnant individual is carrying more than two babies triplets, quadruplets etc.
Your health care provider will schedule your NT ultrasound at a hospital or a clinic with a certified NT sonographer or physician. We are updating the map regularly by removing the NT ultrasound sites that we know to be closed at the moment. However, w e recommend contacting the facility of interest to confirm that their status is up-to-date and that they are offering NT ultrasound services during the evolving COVID pandemic.
This map is merely a tool to assist providers and the public in locating NT ultrasound services in Ontario.

In a high proportion of fetuses with trisomy 21 and other chromosomal abnormalities the nasal bone is hypoplastic or not visible at weeks’ gestation. Our advice is that in such cases the scan should be repeated in one week and if there is persistence of absence of the nasal bone then the risk for trisomies is increased. The requirements for obtaining the FMF certificate of competence in assessment of the nasal bone are:.

Successful completion of a short online test in which you will be asked to examine images on assessment of the nasal bone.

Nuchal Translucency Ultrasound
The early pregnancy scan was initially introduced with the primary intention of measuring the fetal crown—rump length to achieve accurate pregnancy dating. During the last decade, however, improvement in the resolution of ultrasound machines has made it possible to describe the normal anatomy of the fetus and diagnose or suspect the presence of a wide range of fetal defects in the first trimester of pregnancy.
In some conditions, the sonographic features are similar to those described in the second and third trimesters of pregnancy, but in others there are characteristic sonographic features confined to the first trimester. An embryo of 10 postmenstrual weeks is less than half the length of an adult thumb, but already possesses several thousand named structures, practically any of which may be subject to developmental deviations 2.
Thus, the embryonic period proper is of particular importance because the majority of congenital anomalies make their appearance during that time 2. These statements from embryological investigations have become highly relevant for those involved in first-trimester ultrasound scanning.
week antenatal (nuchal translucency) scan · crown-rump length (must be 45 to 84 mm, gestation age 11 weeks 3 days to 13 weeks 6 days) · nuchal.
This was a prospective cohort study of first trimester pregnancies. Non-parametric tests and logistic regression models were used for comparisons of distributions and testing of associations. A total of patients were included, of which were singleton pregnancies, 51 were twins, and 2 were triplets total fetuses. Fifty-two patients had 61 losses. We built nomograms with the changes of the parameters evaluated in ongoing, as well as in pregnancy loss.
The YS reliably identified the occurrence of a miscarriage at least 7 days prior its occurrence. CRL and HR became abnormal at a later time in pregnancy and closer to the event. These findings have important implications for patient counseling and care planning, as well as a potential bearing on cost effectiveness within early pregnancy care.
The difference is explained by a later diagnosis of spontaneous pregnancy versus assisted reproduction pregnancy, and an early loss is easily overlooked.

This first routine scan is carried out for the following reasons:. It is not diagnostic. We also like to arrange this for around 12 weeks, but it can be performed between 10 and 14 weeks.
