Question

All of the following measurements taken on ultrasonography are used to estimate the gestational age of the fetus except_______?

A) Crown-rump length (CRL)

B) Biparietal diameter (BPD)

C) Femur length (FL)

D) Amniotic fluid index (AFI)

Answer 1

The amniotic fluid index (AFI) is not used to estimate the gestational age of the fetus. Crown-rump length (CRL), biparietal diameter (BPD), and femur length (FL) are commonly used measurements for this purpose.

Step-by-step explanation:

Ultrasound measurements are commonly used to estimate the gestational age of the fetus. However, among the measurements taken on ultrasonography, the amniotic fluid index (AFI) is not used to estimate the gestational age of the fetus. The AFI is a measure of the amount of amniotic fluid surrounding the fetus and is not directly related to gestational age estimation. On the other hand, crown-rump length (CRL), biparietal diameter (BPD), and femur length (FL) are commonly used measurements to estimate gestational age as they show consistent growth patterns during different stages of fetal development.
