In this situation, the actual measurement represents the neck—rump length, but it is still termed the CRL. In very early gestations it is not usually possible to distinguish between the cephalic and caudal ends and a greatest length measurement is taken instead.
The biparietal diameter BPD and head circumference HC are measured on the largest true symmetrical axial view of the fetal head, which should not be distorted by adjacent structures or transducer pressure. At about 10 weeks' gestation, structures such as the midline third ventricle, interhemispheric fissure and choroid plexuses should be visible. Towards 13 weeks, the thalamus and third ventricle provide good landmarks. Correct axial orientation is confirmed by including in the image both anterior horns and low occipital lobes of the cerebral ventricles, whilst keeping the plane above the cerebellum 138 - For BPD measurement, caliper placement should follow the technique used to produce the selected nomogram.
Grade A recommendation. Except in pregnancies arising following assisted reproductive technology, the exact day of conception cannot be determined reliably and, therefore, dating a pregnancy by ultrasound appears to be the most reliable method with which to establish true gestational age 39 Many authors have published nomograms for these variables.
Measurements can be made transabdominally or transvaginally. Singleton nomograms remain valid and can be applied in the case of multiple pregnancy 27 It is recommended that CRL measurement should be used to determine gestational age unless it is above 84 mm; after this stage, HC can be used, as it becomes slightly more precise than is BPD It is helpful to look specifically for bone ossification in the axial and coronal planes. No bony defects distortion or disruption of the skull should be present.
The hemispheres should appear symmetrical and separated by a clearly visible interhemispheric fissure and falx. At this early age, some cerebral structures e. Sonographic assessment of NT is part of the screening for chromosomal anomalies and is discussed below.
Attention should be paid to proper alignment of the neck with the trunk and identification of other fluid collections such as hygromas and jugular lymph sacs 28 The chest normally contains lungs of homogeneous echogenicity on ultrasound, without evidence of pleural effusions or cystic or solid masses.
For safety reasons, use of Doppler is not indicated during routine scanning. The position of the stomach on the left side of the abdomen together with levocardia helps confirm normal situs visceralis. By 12 weeks of gestation, the fetal bladder should be visible as a median hypoechoic round structure in the lower abdomen.
The physiological umbilical hernia is present up to 11 weeks and should be differentiated from omphalocele and gastroschisis 2865 The terminal phalanges of the hands may be visible at 11 weeks, especially with transvaginal scanning Figure 7 a. The number of cord vessels, cord insertion at the umbilicus and presence of cord cysts should be noted.
Brief evaluation of the paravesical region with color or power Doppler can be helpful in confirming the presence of two umbilical arteries, but this is not part of the routine assessment.AIUM Webinar: Problem Solving with 3D Sonography of the Uterus and Adnexa
In expert hands, these methods may be helpful in evaluation of abnormalities, especially those of surface anatomy In appropriate circumstances, additional aneuploidy markers, including nasal bone, tricuspid regurgitation, ductal regurgitation and others, may be sought by personnel with appropriate training and certification 74 - This gestational age window is chosen because NT as a screening test performs optimally and fetal size allows diagnosis of major fetal abnormalities, thus providing women who are carrying an affected fetus with the option of an early termination of pregnancy NT implementation requires several elements to be in place, including suitable equipment, counseling and management as well as operators with specialized training and continuing certification.
Further details can be obtained from relevant national bodies and charities such as The Fetal Medicine Foundation www. NT measurements used for screening should only be done by trained and certified operators. NT can be measured by a transabdominal or transvaginal route. The fetus should be in a neutral position, a sagittal section should be obtained and the image should be magnified in order to include only the fetal head and upper thorax.
Furthermore, the amniotic membrane should be identified separately from the fetus. The median view of the fetal face is defined by the presence of the echogenic tip of the nose and rectangular shape of the palate anteriorly, the translucent diencephalon in the center and the nuchal membrane posteriorly. If the section is not exactly median, the tip of the nose will not be visualized and the orthogonal osseous extension at the frontal end of the maxilla will appear.
The ultrasound machine should allow measurement precision of 0. If more than one measurement meeting all the criteria is obtained, the maximum one should be recorded and used for risk assessment. Multiple pregnancy requires special considerations, taking into account chorionicity. A reliable and reproducible measurement of NT requires appropriate training. The echostructure of the placenta should be evaluated.
Placenta previa should not be reported at this stage. Special attention should be given to patients with a prior Cesarean section, who may be predisposed to scar pregnancy or placenta accreta, with significant complications.
Most of these adnexal masses are diagnosed incidentally at the time of dating or first Both transabdominal scan and transvaginal scan (TVS) should be used Functional cyst is the most common adnexal mass in pregnancy, similar to the.
In these patients, the area between the bladder and the uterine isthmus at the site of the Cesarean section scar should be scrutinized. In suspected cases, consideration should be given to prompt specialist referral for further evaluation and management 79 Although the issue of routine scans in women with a history of Cesarean section may be raised in the future 8182there is currently insufficient evidence to support inclusion of such a policy in routine practice.
Abnormalities of uterine shape, such as uterine septa and bicornuate uteri, should be described. The adnexa should be surveyed for abnormalities and masses.

Introduction Routine ultrasound examination is an established part of antenatal care if resources are available and access possible.
GOOD PRACTICE POINT To achieve optimal results from routine ultrasound examinations it is suggested that scans should be performed by individuals who fulfill the following criteria: have completed training in the use of diagnostic ultrasonography and related safety issues; participate in continuing medical education activities; have established appropriate care pathways for suspicious or abnormal findings; participate in established quality assurance programs What ultrasonographic equipment should be used?
How should the scan be documented?
Is prenatal ultrasonography safe during the first trimester? What if the examination cannot be performed in accordance with these Guidelines? What should be done in case of multiple pregnancies?

Guidelines For Examination 1. Defining an intrauterine pregnancy The presence of an intrauterine gestational sac clearly signifies that the pregnancy is intrauterine, but the criteria for the definition of a gestational sac are unclear.
Early pregnancy measurements The mean gestational sac diameter MSD has been described in the first trimester from 35 days from the last menstrual period onwards. Figure 1 Open in figure viewer PowerPoint.
Indications in 1st trimester. ? Dating. ? Previous miscarriage / ectopic. ? Clinical View uterus, adnexa + possible fluid in pouch. View uterus.

Note that choroid plexuses extend from the medial to the lateral border of the posterior horn. Lateral walls of anterior horns are indicated by arrowheads. Measurements should be performed according to techniques described in these articles and tested on the local population before being adopted into practice.
