fetal biometric parameters
Fetal biometric parameters are antenatal ultrasound measurements that are used to indirectly assess the growth and well being of the fetus.
Standard parameters
Assessed and reported on a routine 2-trimester scan or when growth reassessment is required in the second or third trimester.
- biparietal diameter (BPD)
- head circumference (HC)
- abdominal circumference (AC)
- femur length (FL)
Additional parameters
- humeral length (HL)
- renal pelves / fetal pyelectasis (FP)
- trans-cerebellar diameter (TCD)
- occipito-frontal diameter (OFD)
- interocular distance (IOD)
- binocular distance (BOD)
- ratios
- fetal cardio-thoracic circumference ratio
- fetal thoracic to abdominal circumference ratio
- fetal thoracic to head circumference ratio
