The average value of cephalic index in children up to 3 years of age amounted to 81.45 ± 7.06. The index value in case of children under 3 months was 80.19, 4 to 6 months was 81.45, 7 to 12 months was 83.15, in children under 2 years was 81.05, and in children under 3 years was 79.76.
How do you calculate the cephalic index?
The cephalic index (CI) is a value calculated using two fetal biometric parameters which are the occipitofrontal diameter (OFD) and the biparietal diameter (BPD). It is calculated as: cephalic index (CI) = biparietal diameter (BPD)/occipitofrontal diameter (OFD) x 100.
What is a BPD measurement?
BPD (biparietal diameter), the diameter of your baby’s head. HC (head circumference), the length going around your baby’s head. CRL (crown-rump length), the length from the top of the head to your baby’s bottom, measurement taken in the first trimester.
What does a low cephalic index mean?
The cephalic index is the breadth multiplied by 100 divided by the length. An index of less than 75 means that the skull is long and narrow when seen from the top; such skulls are called dolichocephalic and are typical of Australian aborigines and native southern Africans.
What is normal bpd HC AC FL in pregnancy?
Your doctor is looking for the BPD measurement, as well as the other measurements, to be within what is considered normal range. The biparietal diameter measurement increases from roughly 2.4 centimeters at 13 weeks to approximately 9.5 centimeters when a fetus is at term.
What’s the meaning of cephalic?
Definition of cephalic
1 : of or relating to the head cephalic measurements. 2 : directed toward or situated on or in or near the head gastropods with cephalic tentacles dragons with cephalic horns.

What is normal FL in pregnancy?
Femur length (FL)
Measures the longest bone in the body and reflects the longitudinal growth of the fetus. Its usefulness is similar to the BPD. It increases from about 1.5 cm at 14 weeks to about 7.8 cm at term.
What is normal bpd FL ratio?
The normal ratio of femur length to BPD (FL/BPD ratio) was found to be 79 +/- 8%. Effective uses of the FL/BPD ratio include its use as a quality control check on femur length and BPD measurements and its use to diagnose short-limbed dwarfism, hydrocephalus, and microcephaly.
What is cephalic index in ultrasound?
The Cephalic Index, also referred to as cranial ratio or cephalic ratio is the measurement that will be used to categorize your infants head shape. The CI is the measured width of the head divided by the length of the head multiplied by 100 and reported as a percentage.
Can I shape my baby’s head?
You can help your baby’s head return to a more rounded shape by altering her position while she’s asleep, feeding and playing. Changing your baby’s position is called counter-positioning or repositioning. It encourages the flattened areas of your baby’s head to reshape naturally.
How do you fix Brachycephaly?
No treatment is necessary for mild cases of brachycephaly and plagiocephaly. Your baby’s skull should naturally correct itself over time if you take some simple measures to take pressure off the flattened part of their head and encourage them to try different positions.

Mean BPD showed an increase of 2.38 cm in 13-20 weeks, 2.18 cm between 20 and 27 weeks and only 1.72 cm from 27 to 34 weeks. Average growth rate of BPD was found to be 0.31 cm/week from 13 to 28 week, which then later reduced to 0.23 cm/week from 28 to 36 weeks of gestation.
What is normal bpd in pregnancy in MM?
Results: The mean biparietal diameter value was 29.4mm at 14 weeks, 49.4mm at 20 weeks, 78.4mm at 30 weeks, 91.5 at 37 weeks and 95.6mm at 40 weeks. There was a positive relationship between gestational age and biparietal diameter with correlation coefficient of R2 = 0.9996 (P < 0.001), and with fetal weight.
What should be the BPD at 36 weeks?
For example, a single BPD value of 9.0 cm is considered normal if the length of pregnancy is 36 weeks (Table 2).
How do I know if my baby is cephalic?
- feel their head low down in your belly.
- feel their bottom or legs above your belly button.
- feel larger movements — bottom or legs — higher up toward your rib cage.
- feel smaller movements — hands or elbows — low down in your pelvis.
Is cephalic position good?
About 95 percent of babies drop down into the head-first position a few weeks or days before their due date. This is called the cephalic position, and it’s safest for mom and baby when it comes to giving birth.
Does cephalic mean head?
Cephalic: Relating to the head or the head end of the body. Situated on, in, or near the head. Cephalic is synonymous with cranial, relating to the cranium or head. The word “cephalic” came from the Middle French “cephalique,” from the Latin “cephalicus”, from the Greek “kephalikos” meaning head.

Who came up with the cephalic index?
The cephalic index was defined by Swedish professor of anatomy Anders Retzius (1796–1860) and first used in physical anthropology to classify ancient human remains found in Europe.
Does sleeping position affect baby’s head?
Although sleeping position can cause a misshapen head to develop in little ones, there are some useful practices that can be adopted by parents to reduce the likelihood of a flattening developing. These methods can also help a flattening to improve if it has already developed.
Why is my baby’s forehead so big?
The large, bulging forehead is a sign of the body protecting itself — the child’s skull is compensating for the premature fusion and allowing normal brain growth to continue. The long, narrow skull that results from sagittal synostosis is known as scaphocephaly, sometimes referred to as a “boat shape.”
How do I do tummy time with my baby?
Tummy time can also help your baby build strength needed for sitting up, rolling over, crawling and walking. Start tummy time by spreading out a blanket in a clear area. After a diaper change or nap, place your baby on his or her stomach on the blanket for three to five minutes. Try doing this two to three times a day.
What is a Dolichocephalic skull?
What Is Dolichocephaly? Dolichocephaly refers to an elongation of an infant’s head caused most often by positioning after birth. It is commonly, though not exclusively, a result of an extended stay in neonatal intensive care unit (NICU).
What does brachycephaly look like?
Brachycephaly, or flat head syndrome is a head shape condition where the head is wide in proportion to the length. It creates a flattened but symmetrical appearance in the back. Often the head appears vaulted or taller in the back.
Do I have Scaphocephaly?
Signs of Scaphocephaly Head Shape
One of the most common signs of scaphocephaly is an elongated head shape, with the sides of the skull appearing narrow and the forehead prominent when looking down.
How accurate are bpd measurements?
The BPD is the most widely used measure, with greatest accuracy between 12 and 22 weeks, declining after this period because of a wider individual variation. The BPD demonstrates linear growth of 3 mm per week from weeks 14 to 28, and 2 mm per week until term.
What is more important BPD or HC?
Conclusion: Given an expected pregnancy duration of 282 days, both HC and BPD predicted spontaneous birth with a mean accuracy of one day, HC being significantly better than BPD. The study confirms the assumption that HC is a more robust method of assessing gestational age and time of confinement.
Is there an assessment for borderline personality disorder?
While mental health professionals may use screening tools to help diagnose BPD, a single, definitive diagnostic test for borderline personality disorder doesn’t exist. Instead, a licensed mental health provider will diagnose BPD through a thorough assessment.
