Method |
Imaging conditions (degradation due to fetal movement, maternal obesity, premature termination of examination) and technical specifications (field strength, coil, sequences, planes) |
Head |
Normality of profile with intact hard and soft palate (Figure 7) |
Brain |
Age‐related normality of sulcation and gyration, regularity of lamination of brain parenchyma (after 30 gestational weeks: regularity of myelination and premyelination), normality of midline structures and normality of width of cerebrospinal fluid‐filled spaces (Figure 2) |
Chest |
Regularity of configuration of the thorax with age‐matched normal signals of the lungs (Figure 8). Regularity of heart on gross examination; detailed examination not performed |
Abdomen |
Stomach and gallbladder fluid‐filled, regularity of fluid (Figure 9a) and meconium signals of the bowels (Figure 4), presence of kidneys, urinary bladder fluid‐filled (Figure 9b); on request: normality of female/male external genitalia (in males: descended testes, yes/no) (Figure 10) |
Extrafetal structures |
Three‐vessel umbilical cord, normality of amniotic fluid volume, position and regularity of structure of placenta, according to age
54
, cervical length (Figure 11) if shortened |
Skeleton (optional, if examined on request) |
Course and completeness of spine, and shape, length and position of bones, including fingers and toes (if digits assessable sufficiently; this will not always be possible, particularly when amniotic fluid is minimal, after 32–35 gestational weeks) |
