However, not all pregnant women know the signs on the ultrasound results sheet.

Significant important parameters of the fetus

CRL: crown rump length (length from butt end)

BPD: biparietal diameter

TTD: Diameter at belly height

APTD: Diameter before and after abdomen

AC: abdominal circumference

FL: femur length (femur length)

GS: gestational sac diameter (fetal sac diameter)

HC: head circumference

AF: amniotic fluid (amniotic fluid)

AFI: amniotic fluid index (amniotic fluid index)

OFD: occipital frontal diameter

BD: binocular distance (two eyes distance)

CER: cerebellum diameter

THD: thoracic diameter (chest diameter)

TAD: transverse abdominal diameter

APAD: anteroposterior abdominal diameter (front to back abdomen diameter)

FTA: fetal trunk cross-sectional area

HUM: humerus length (arm bone length)

Ulna: ulna length (elbow length)

Tibia: tibia length (shin length of the shin)

Radius: Length of the rotating bone

Fibular: Length of fibula

EFW: estimated fetal weight

GA: gestational age (gestational age)

EDD: estimated date of delivery

Abbreviations are used to describe the baby's lying position in the womb. Here are some poses:

CCPT: The occipital rotates to the right, brought forward.

CCTT: The occipital rotates to the left, brought forward.

CCPS: Right occipital rotating back

CCTS: The occipital rotated to the left and rear.
