Background Placental volume measurements can potentially identify high-risk pregnancies. We aimed to develop and validate a new method for placental using tracked 2D ultrasound automatic image segmentation.
Our objective was to study the association of placental size, fetal and size relative (placental ratio) at gestational week 27 with time spontaneous delivery. We included 100 pregnancies in a follow-up from until Placental volume (in cm3) were measured by magnetic resonance imaging (MRI), ratio volume/fetal volume) delivery after onset labor estimated as hazard ratios (HR) applying Cox regression models. Pregnancies deliveries planned cesarean section or induction provided these events. An...
Abstract Introduction Ultrasound is the diagnostic tool of choice in pregnancy. We lack valid ultrasound methods for placental size measurements. Our aim was therefore to compare three‐dimensional (3D) with magnetic resonance imaging (MRI) measurements volume. Material and measured volume by 3D MRI 100 unselected pregnancies at 27 weeks gestation (25 +4 –28 weeks). The acquisitions were analyzed offline, outline manually traced using virtual organ computer‐aided analysis (VOCAL) 30°...
Information about placental size in ongoing pregnancies may aid the identification of with increased risk adverse outcome. Placental volume can be measured using magnetic resonance imaging (MRI). However, this method is not universally available antenatal care. Ultrasound diagnostic tool choice pregnancy. Therefore, we studied whether simple 2D ultrasound measurements were correlated by MRI. We examined a convenience sample 104 at gestational week 27, both and The included length, width...
