Cardiovascular system. Fetal
heart activity was detectable by use of gray-scale US at 10.5 DPC in
all gestations. Blood flow within the umbilical cord was demonstrated at
this time point as well by use of power Doppler color imaging. Power
Doppler color imaging of the heart revealed the interventricular septum
by 14.5 DPC and the atrial septum at 17.5 DPC. The interventricular
septum could be detected by use of gray-scale at 16.5 DPC. By 11.5 DPC,
blood flow could be demonstrated within the major thoracoabdominal
arteries, and the circulation could be followed within the ascending,
descending, and abdominal aorta and into the hypogastric arteries, umbilical cord, and
placenta (Figure 6).
The carotid arteries (Figure 7 A) and circle of Willis (Figure 8) became apparent at 13.5 DPC, and the circle of Willis was easily visible by 15.5 DPC. Finally, the renal arteries could be seen with Doppler color imaging at 15.5 DPC (Figure 7 B).

Figure 5. The regression line demonstrating the relationship between BPD and GA is shown. See also Table 2.
Figure 4. The regression line demonstrating the relationship between CRL and GA is shown. As an example, a fetal mouse with CRL of 10 mm would be predicted to have a GA of 5 + 9 = 14 d. For each unit increase of 1 mm in CRL, we predict an increase in age of 0.5 d (that is, slope of the fitted line). The positive linear correlation is strong (r = 0.97, P < 0.0001). See also Table 1
