Hi Archie & Curious
thanks for all ur support for the past few months.. i had my first scan today and saw the baby for the 1st time.. the baby is moving and saw the heart beats as well.. it was a wonderful experience to c the baby. both my husband and i was soo very happy to c the baby .

i am just writing the report for u
according to scan
ultra sound age=13 weeks 6 days
no. of fetus= 1
presentaion=mobile
placental site=anterior
FI=normal
fetal measurements:
BPD=25
HC=82
AC=67
FL=10
CRL=77
EDD=12/04/07

The doc said everything seems to be perfect as of now but i didnt get the terms like FL, CRL.. could you please explain them?
doing you thing by the measurements everything is absolutely normal?

thanks once again
waiting for u to reply

These values look absolutely normal. I can so relate the excitement you and your hubby must have shared when u saw/heard the baby's heartbeat (umbilical cord etc). Its one helluva feeling. And I always like the zeal people have to know about things.

CRL is Crown Rump length. Basically, thats the length of the baby from the head (crown) to the tip of the buttocks (not all the way till the toes). This is usually relied upon to calculate the fetal age until about 12 weeks (and since the length keeps growing and the baby sits in a folded position, thats a relatively not-so-deterministic way to evaluate things).

So, usually, after 12 weeks, they move onto more significant parameters.
BPD = Biparital Diameter (this is the diameter of the head of the fetus)
HC = Head circumference
AC = Abdomen circumference
FL = Femur length

There are several formuale followed by different systems to arrive at the fetal weight and age based on the above parameters. (Hadlock's one being the most used i hear). There are certain softwares that puts your baby's fetal weight/age in certain percentiles. No need to follow them so closely (unless you are truly interested in knowing everything about your baby....thats how i was with my first baby...i wanted to know every damn thing...so i would sit and google out everything...although you come across things on the web that might scare you off and put in some apprehensions/fears, you will still feel so equipped with all the information that you begin to enjoy the pregnancy in its truest sense...you kinda feel you are growing with your baby and feeling everything that your babys feeling in your tummy).

All in all, these measurements look pretty good.

Hadlock BPD/FL/AC formula:
Log 10 birth weight = 1.4787 + 0.001837 (BPD)2 + 0.0458 (AC) + 0.158 (FL) - 0.003343 (AC x FL)
Take a scientific calculator and evaluate it for yourself. :-)

Happy pregnancy

Sunil. archie replied. these terms are helpful to understand babys development as a whole. They consider head, abdomen and measure longest bone of the body 'femur'.

baby looks fine.
