Fetal Biometry in the Israeli Population: New Reference Charts
The Israel Medical Association Journal : IMAJ
|March 12, 2016
Summary
New Israeli fetal biometry charts were developed for accurate diagnosis. These charts, based on over 79,000 fetuses, are recommended for routine obstetric practice to improve fetal growth assessment.
Area of Science:
- Obstetrics and Gynecology
- Fetal Medicine
- Medical Imaging
Background:
- Accurate fetal biometry is crucial for diagnosis.
- Current reliance on US-based charts is suboptimal for the Israeli population.
- Local reference charts are needed for improved accuracy in Israel.
Purpose of the Study:
- To create new reference charts for fetal biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL).
- To cover gestational ages from 14 to 42 weeks.
- To utilize data from a large, diverse Israeli population.
Main Methods:
- Pooled data from a medical center and community ultrasound unit in Israel.
- Calculated weekly means and standard errors for biometric measurements.
- Developed reference charts using normal distribution quantiles.
Main Results:
- Data from 79,328 fetuses were analyzed.
- New growth charts for fetal biometry were successfully established.
- The charts demonstrated very good overall performance, with minor variations in higher quantiles.
Conclusions:
- New, localized reference charts for fetal biometry in Israel have been developed.
- These charts are derived from a large, minimally selected Israeli population.
- Implementation in routine obstetric practice is recommended for improved fetal assessment.

01:17z Scores and Area Under the Curve
20.1K
z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

01:52Regression Toward the Mean
7.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

01:11Normal Distribution
18.1K
The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...

A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
