11982-6
ClinicalFetal Head Circumference derived from occipital-frontal diameter and outer-outer transaxial diameter (US)
Definition
Derived from measures of occipital-frontal diameter and transaxial diameter assuming shape is an ellipse. The outer to outer transaxial diameter is used. This estimate should be closer to that measured with ellipse overlay or by tracing.
