Fig. 1.1 The crown-rump length is a measurement of the length of human fetuses from the top of the crown to the bottom of the rump. It is used to estimate gestational age.

Fig. 1.2 Transvaginal ultrasound and sagittal long-axis view of the endocervical canal. Both the internal os and the external os are well visualized. The cervical length is measured from the internal os to the external os along the endocervical canal.

Fig. 1.3 Sagittal view of the uterus with an anterior (Ant) placenta.

Fig. 1.4 Sagittal view of the uterus showing a posterior (Post) placenta.

Fig. 1.5 Normal umbilical cord insertion into the placenta.

Fig. 1.6 Fetal umbilical cord insertion site. The umbilical arteries emerge caudally—originating at the iliac arteries and coursing along the margin of the urinary bladder. The umbilical vein proceeds cephalad and joins the fetal portal circulation. 3V, Three-vessel.

Fig. 1.7 Transverse view of the umbilical cord. The umbilical cord is composed of a vein and two smaller arteries.

Fig. 1.8 Transverse view of the fetal abdomen and the umbilical cord insertion site showing integrity of the central abdominal wall.

Fig. 1.9 Four-chamber view of the fetal heart at 12 weeks of gestation.

Fig. 1.10 Interventricular septum at 12 weeks of gestation.

Fig. 1.11 Left ventricular outflow at 12 weeks of gestation. LVOT, Left ventricular outflow tract.

Fig. 1.12 Three-vessel view shown by color Doppler at 12 weeks of gestation.

Fig. 1.13 Aortic arch (Ao Arch) at 12 weeks of gestation.

Fig. 1.14 Four-chamber view obtained with a transverse axial view through the fetal thorax. This view provides information on the size of the heart and its chambers; the pulmonary venous connections to the atrial segment; the morphology of the ventricles; the type of atrioventricular (AV) connection; and ...
