    Objective To improve the diagnostic accuracy level of ultrasound in diagnosis of fetal anomaly of multiparous pregnancy. Method Retrospective analysis was performed on 45 cases of fetal anomalies with multiparous pregnancy diagnosed by ultrasonography in our hospital from January 2000 to June 2006. Results Most fetal anomalies of multiparous pregnancy detected by ultrasonography in the second trimester gestation. There were similar fetal anomalies between monoparous and multiparous pregnancy,and also some special anomalies in multiparous pregnancy. Conclusion Ultrasonography is the main method for diagnosing fetal anomaly of multiparous pregnancy.

    To assess whether additional CT or MRI, rather than a repeat ultrasound investigation, is the most appropriate diagnostic approach for patients with clinical suspicion of appendicitis following an inconclusive first ultrasound.Descriptive study.Retrospective data analysis of patients admitted to ER with clinical suspicion of acute appendicitis, on whom at least one ultrasonography had been performed.A total of 328 patients were included of which 81 patients had an inconclusive first ultrasonography. Twenty-five patients underwent a second ultrasound test, and in 17 patients a correct diagnosis could be made. The positive and negative predictive value of a second ultrasonography, following an inconclusive first one was 97% and 99% respectively.Following an inconclusive first ultrasonography in patients suspected of having acute appendicitis, a second ultrasound after an observation period can be considered, rather than opting for additional CT or MRI imaging.

    Objective To explore the clinical value of early in pregnancy, ultrasound screening and diagnosis of fetal. Methods During 2012 February to 2013 in our hospital were chosen in February to accept early in pregnancy, ultrasound screening and diagnosis of 200 cases of pregnant women, accept ultrasound screening in early pregnancy and pregnant metaphase respectively, statistics of fetal anomaly detection rate and abnormal condition. Results 200 cases, 220 fetus in early pregnancy, ultrasound screening in the check out the 15 fetal abnormality(6.81%); 190 in the second trimester fetal ultrasound screening in the check out the 5 cases of abnormal(2.63%). Conclusion Early pregnancy will check out part of severely abnormal fetus, pregnant metaphase will check out early did not appear abnormal situation. So, to be combined with early in pregnancy, ultrasound screening and diagnosis of fetal anomaly, prenatal diagnosis has important value for clinical.

    Abstract Improvements in ultrasound technology, including transvaginal sonography and higher frequency probes, have led to a better understanding of early pregnancy development. These advances and the increasing availability of ultrasound allow women to have an earlier and more accurate assessment of their pregnancy. First trimester sonographic signs have been identified that can be used to reassure women that their pregnancy is progressing normally or counsel them that their pregnancy will fail. In addition, first trimester ultrasound can accurately predict the type of twinning in multiple gestations, allowing for appropriate counseling and management. Objectives Know the first trimester ultrasound findings of a normal intrauterine pregnancy Understand the ultrasound findings that diagnose an early pregnancy failure Know the ultrasound criteria used to diagnose a multifetal gestation

    The purpose of this work was to determine the value of ultrasound investigation of the placental tissue in fetal assessment during post-term pregnancy. 80 pregnant women from 39 weeks gestation till delivery were examined in this long term study. The investigation was performed every 5-7 days until the labor. They were divided into three groups. The first group included 40 pregnant women with post term pregnancy, the second, 30 women with prolonged pregnancy. The control group consisted of 10 practically healthy pregnant women. Ultrasound parameters of fetal biometry such as the BPD, APTD, TTD and dynamics of placental thickness changes were analyzed. Our results suggest that the post term pregnancy can be differentiated from prolonged pregnancy by ultrasound assessment of placental tissue (monitoring of changes in placental thickness) and results of fetal biometry (BPD, APTD, TTD).

    Diagnostic ultrasound has been used increasingly in obstetric practice over the past decade. To date, adverse effects of ultrasound on the fetus have not been reported, but studies have been done on small sample sizes. This study looks specifically at the association of ultrasound exposure during pregnancy and the risk of low birthweight in the offspring. A validation case-control study was also performed based on information from a sample of medical charts. With a database of more than 13,000 pregnancies, there was no indication of an adverse effect of ultrasound performed during the first two trimesters of pregnancy.
