title: Fetuses aren't small children.
abstract: Although great strides in prenatal diagnosis have been made by sonography, interpretation has been complicated by failure to recognize fundamental differences between the uterine and extra-uterine environment. Furthermore, extrapolation of knowledge concerning the same disorders in childhood to fetuses produces misleading information about diagnosis and often, prognosis.
