“…The utilization of US in the routine prenatal follow-up has allowed pregnancy monitoring at the first gestational trimester (6) , and this method has been the main imaging tool both in the normal prenatal follow-up and diagnosis of first-trimester abnormalities, with diagnostic criteria well established in the literature for the main abnormalities in this period (7) , besides being the method of choice as the first approach for pregnant patients in emergency departments (2) . The sonographic aspect of ectopic pregnancy varies according to the gestational age and location (7) .…”

O objetivo deste trabalho é descrever os principais achados de tomografia computadorizada e ressonância magnética em pacientes com dor abdominal aguda causada por gravidez ectópica. Para isso, dois radiologistas em consenso selecionaram e analisaram exames de tomografia computadorizada e ressonância magnética realizados entre janeiro de 2010 e dezembro de 2011 de pacientes com dor abdominal aguda comprovadamente decorrente de um quadro de gravidez ectópica. O diagnóstico por imagem de gravidez ectópica é usualmente obtido por ultrassonografia, no entanto, o uso crescente da tomografia computadorizada e ressonância magnética na avaliação do paciente com abdome agudo de origem ginecológica tem requerido que o radiologista se familiarize com os principais aspectos observados nestes métodos diagnósticos.

Objectives: To study the influence of maternal hematocrit(Ht) and hemoglobin (Hb) levelon placental volumewithstudy ofuterine artery Doppler. Subjects and Methods: In this prospective study 40 pregnant(singleton pregnancy) cases were selected from the outpatient clinic of Alzahra university Hospital. They were divided into two groups the study group (20 cases)were anemic(iron deficiency) and the control group(20cases) were healthy. For each case two scans for the placenta and fetal growth were performed, the first at recruitment and the second 5 weeks later. Placenta volume was measured at each visit using three dimensional ultrasound. The maternal Hb and (Ht) were measured in each visit. Results: It revealed a non statistical significance between maternal hemoglobin, hematocrit and placental volume during the 1st visit and 2 nd visit in anemic group compared to the control group.As regards Doppler study of the uterine artery in the present study it was noted that the pulsatility index and resistance index showeda non significant increase in the anemic group compared to the control group. Conclusion:Maternal iron deficiency anemia can affect placental growth and development. Placental volume increased with mild anemia during the first trimester but has no significant effect of fetal growth.The use of 3D ultrasound is more accurate and efficient safe technique of great value in evaluating placental growth and volume. Also, the study of uterine artery blood flow during the mid second trimester showed a nonsignificant increase of RI and PI with maternal anemia. Further study are needed for the effect of anemia on fetal growth during preconceptional, first,second,third trimester and the outcome of pregnancy.
