Individualized growth assessment of fetal thigh circumference using three-dimensional ultrasonography.
OBJECTIVES: To develop individualized growth assessment (IGA) standards for upper (ThC(u)) and middle (ThC(m)) fetal thigh circumferences using three-dimensional ultrasonography. METHODS: A prospective, longitudinal sonographic study of 30 fetuses was performed beginning at 18 weeks’ menstrual age. Second-trimester sonographic parameters were measured from three-dimensional volume data […]
