title: [Prenatal diagnosis by ultrasonography. A randomized study of 3000 patients].
abstract: From January through December, 1990 at Hospital de Ginecoobstetricia Tlatelolco, 3,000 pregnant women were subjected to ultrasonography at random using a real time, B mode apparatus with a 3.5 MHz lineal transducer. Fetal malformation were diagnosed, some of which would have passed undetected in the labor room with consequent delay of treatment and false raise of perinatal morbidity and mortality rates.
