How To Measure Amniotic Fluid Index (AFI) On Ultrasound | Probe Position & Scanning Technique USG

How To Measure Amniotic Fluid Index (AFI) On Ultrasound | Probe Position & Scanning Technique USG
- The uterus is divided into four quadrants using the umbilicus as a reference point: Right upper quadrant (RUQ), Left upper quadrant (LUQ), Right lower quadrant (RLQ), Left lower quadrant (LLUQ)
- For each quadrant, the ultrasound transducer is placed on the maternal abdomen to locate the deepest, unobstructed pocket of amniotic fluid that is free from fetal parts or umbilical cord loops.
The vertical depth (in centimeters) of this pocket is measured.
- No horizontal measurement is taken.
If there's an obstruction (like a fetal limb) that divides a pocket, neither section of that pocket is measured. Instead, look for another pocket within that quadrant.
- Calculate the AFI: The depth measurements from each of the four quadrants are added together to calculate the total AFI. The sum of these four measurements provides the AFI in centimeters.
AFI (cm) = Q1 + Q2 + Q3 + Q4
- Normal AFI: The typical range for AFI is between 5 and 25 cm.
Oligohydramnios: AFI less than 5 cm.
Polyhydramnios (or hydramnios): AFI greater than 25 cm.

[@lawrencessebanakita5928]

Thanks so much Dr...for these videos are precious to us!,my humble inquiry is, can AFI be converted into mls ?

[@DrSamsImagingLibrary]

Most Welcome! There isn't a straightforward formula to convert AFI directly to milliliters because they measure different aspects of the fluid (depth vs. volume).

[@MohinderSinghJassal]

Dr. Sam ,you have well explained the method of calculating AFI . Is there any guideline regarding normal AFI values in third trimester of pregnancy as volume is normally less in later weeks of pregnancy ?

[@DrSamsImagingLibrary]

Thank you! Although Amniotic fluid volume decreases in third trimester, AFI should still be above 5cm in normal cases.
