OP09. 09: Volumetric measurements of the cervix by 3D ultrasonography do not improve the prediction of preterm delivery when compared to cervical length measur... Academic Article uri icon


  • Objective The purpose of this study was to compare the diagnostic performance of cervical measurements by two-dimensional (2DUS) and three-dimensional ultrasonography (3DUS) for the prediction of early spontaneous preterm delivery (< 32 weeks). Methods Ninety-one singleton asymptomatic pregnancies at risk for preterm delivery (history of spontaneous preterm delivery, conization, cervical insufficiency, or a cervical length< 25 mm in the second trimester) were examined by transvaginal ultrasonography between 22 and 24 weeks of gestation. Following cervical length measurement by 2DUS, a 3DUS volume dataset was acquired using the sagittal acquisition plane. Volumes were retrospectively examined offline by an examiner blinded to the results of the 2DUS examination. Cervical length was measured in the sagittal plane displayed with the multiplanar technique. Cervical volume …
