Second & Third Trimesters - Module 1: Fetal Biometry and Amniotic Fluid

Jim Baun, BS, RDMS, RVT, FSDMS begins the Second and Third Trimester section by discussing biometric parameters and “Rule of Thumb” of normal measurements. The technique is demonstrated for assessment of biparietal diameter, head circumference, cephalic index, abdominal circumference, and femur length. Technical pitfalls are discussed to improve accuracy of sonographic measurements. Gestational age estimation by epiphyseal appearance is shown through case examples. Techniques for orbital and transcerebellar diameter measurements are shown as useful adjuncts to the standard biometric determinations. Biophysical profile scoring is covered as well. This module concludes with a section on assessment of amniotic fluid, including estimation of amniotic fluid volume, the amniotic fluid index (AFI), and amniotic abnormalities.
