A comprehensive severity score for the morbidly adherent placenta: combining ultrasound and magnetic resonance imaging.

Background: Ultrasound (US) is the first-line imaging modality to assess the morbidly adherent placenta, but sensitivity and specificity are lacking.

Objective: This investigation aims to improve diagnostic accuracy with a comprehensive score using clinical history, US, and magnetic resonance imaging (MRI).

Materials And Methods: We conducted a retrospective cohort study of pregnant women who received both transvaginal US and MRI with suspicion for morbidly adherent placenta between 2009 and 2016.

Uterocervical Angle Measurement Improves Prediction of Preterm Birth in Twin Gestation.

Objective: Twin pregnancies are associated with an increased risk of spontaneous preterm birth. Our objective was to compare the performance of uterocervical angle to cervical length as predictors of spontaneous preterm birth in this population.

Methods: We conducted a retrospective cohort study of twin gestations at a single center from May 2008 to 2016 who received a transvaginal ultrasound for the evaluation of the cervix between 16 0/7 and 23 0/7 weeks.

Effect of Maternal Retroplacental Leiomyomas on Fetal Growth.

Objective: To evaluate the association between retroplacental leiomyoma identified on second trimester ultrasound and fetal growth.

Methods: We performed a retrospective study comparing the presence or absence of one or more retroplacental leiomyomas on birth weight in a cohort of women with singleton pregnancies undergoing second trimester fetal anatomic ultrasound at our institution between 2007 and 2012. The incidence of small for gestational age (SGA) infants was recorded.
