OBJECTIVES To determine if fetal volume (FV) measurements with three-dimensional ultrasound in the first trimester of pregnancy can detect the fetus at risk for preterm birth and/or low birth weight. METHODS In this prospective cohort study, 538 participants were included during the routine first trimester ultrasound examination. Volume measurements were(More)
OBJECTIVES To determine the inter- and intra-observer variation of volume calculations of human fetuses at a gestational age of 11(+0)-13(+6) weeks by three-dimensional ultrasound (3DUS). METHODS 3DUS datasets were acquired during nuchal translucency measurements. The fetal volume (FV) was measured in 65 cases by two independent investigators. The Virtual(More)
BACKGROUND Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective,(More)
BACKGROUND The goal of this study was to calculate the accuracy of three-dimensional volume measurements with the rotational multiplanar technique VOCAL (Volume Organ Computer-aided AnaLysis). METHODS An ultrasound phantom with 13 objects (volume 10.2-40.5 cm(3)) was created. After data acquisition, the volumes of the objects were measured with the VOCAL(More)
BACKGROUND First trimester growth restriction is associated with an increased risk of adverse birth outcomes (preterm birth, low birth weight and small for gestational age at birth). The differences between normal and abnormal growth in early pregnancy are small if the fetal size is measured by the crown-rump-length. Three-dimensional ultrasound volume(More)
OBJECTIVE Complications in pregnancy are suggested to be the result of intrauterine conditions in the first trimester of pregnancy. Three-dimensional ultrasound volume measurements might give more information, compared with two-dimensional measurements. Commonly available methods for volume measurements are not suited for daily practice. This is a report of(More)
