Abstract (sommario):

Abstract Objective. This work investigates the use of deep convolutional neural networks (CNN) to automatically perform measurements of fetal body parts, including head circumference, biparietal diameter, abdominal circumference and femur length, and to estimate gestational age and fetal weight using fetal ultrasound videos. Approach. We developed a novel multi-task CNN-based spatio-temporal fetal US feature extraction and standard plane detection algorithm (called FUVAI) and evaluated the method on 50 freehand fetal US video scans. We compared FUVAI fetal biometric measurements with measureme

Abstract (sommario):

AbstractUltrasound estimation of fetal weight or ultrasound measurement of fetal abdomen alone enables identification of small-for-gestational-age fetuses. A prerequisite for this is a reliable dating of pregnancy, which is provided by a routine ultrasound screening in the first half of gestation. The fetal growth can be followed by serial fetometric measurements. As a standard, charts of intrauterine growth based on the ultrasonic measurement can be used. As a secondary diagnostic test for monitoring fetal health in pregnancies suspected of intrauterine growth retardation, Doppler ultrasound

Abstract (sommario):

Measurement of fetal femur length is crucial for the estimation of fetal age and growth pattern. Due to the noisy nature of ultrasound images and the variation in image acquisition and measurement techniques, manual measurements are subject to interobserver and intraobserver variability. The motivation of this paper is to study the efficiency of automated methods used in the femur endpoint detection module of our proposed computer-assisted processing and analysis system, which is employed to determine the gestational age for promoting the standardization of fetal femur measurements, thus resul

Abstract (sommario):

AbstractIn 65 consecutive twin pregnancies, 722 measurement of fetal abdominal circumference have been obtained with ultrasound. Zygosity was established after delivery in 85% of the pregnancies. There was no difference in mean abdominal circumference measurements between monozygotic and dizygotic pregnancies. In both groups, the pattern of growth was linear throughout pregnancy in contrast to that predicted by birth-weight for gestational age charts. It is suggested that increasing trunk flexion, in later twin pregnancy, may distort accurate abdominal circumference measurement.

The continuous use of fetal Doppler allows for discrepancies in values that lead to misdiagnoses in patients. This study aims to determine the effect of sound source distance on the fetal simulator with the measurement point. The contribution of this research is that the mechanical fetal heart system has 4 distances so that later it can be analyzed whether there is an influence of the location of the sound source on the accuracy of measurements using a fetal simulator. To get the desired distance, a solenoid is used which ends with a pipe of 2 cm, 5 cm, 10 cm, and 50 cm respectively. The sol

Fetal movement has always been considered an essential indicator to evaluate the health of the unborn fetus. Many factors affect fetal movement. The frequency of fetal kicking is an important measurement of whether fetal development is progressing and healthy. Various instruments and methods of detecting fetal movement have been used and each method has its advantages and disadvantages. Although limited by the fetal environment in utero, the finite element method and musculoskeletal model can be used to calculate fetal lower limb movement.

Fetal biometry plays an important role in every woman's antenatal care. As clinical decisions are based on these measurements it is imperative that standards are kept high and all departments use standardised charts. Thus minimising inaccurate diagnoses in fetal dating and growth estimation, which may have serious consequences for fetal well being. Standardisation of fetal biometry was assessed by circulating a postal questionnaire to superintendent sonographers in 121 hospitals within the Thames regions.

Abstract Accurate measurement of fetal biometrics in ultrasound at different trimesters is essential in assisting clinicians to conduct pregnancy diagnosis.

Today’s fetal monitors are based on monitoring of mechanical activity of the fetal heart by means of Doppler ultrasound technique. The FHR is determined using autocorrelation methods, and thus it has a form of evenly spaced—every 250 ms—instantaneous measurements, where some of which are incorrect or duplicate.

The transabdominal, fetal pulse oximetry is a promising approach to measure this non-invasively and continuously.

For this purpose efficient algorithms are necessary, which have to be evaluated under constant and reproducable test conditions.

Abstract (sommario):

Objectives: To assess the inter- and intraobserver reliability of different fetal MRI measurements in cases of fetal brain malformations and to examine the concordance between ultrasonography (US) and MRI findings. Methods: Fetal brain MRIs and US findings of 56 pregnant women were retrieved from the institutional database. Standardized fetal brain MRI measurements were performed by 4 observers, and the inter- and intraobserver reliability was determined. Additionally, US and MRI findings were retrospectively compared. Results: The interobserver intraclass correlation coefficient (ICC) was abo

Abstract (sommario):

Eleven fetal lambs were tested for auditory brain stem responses (ABRs) at 105 and 90 db sound pressure level from 110 to 116 days until 133 days gestation. ABRs were elicited in response to 1200 clicks, presented at 16 clicks/sec, from a hearing aid receiver secured in the fetal external ear canal and recorded from subdermal stainless steel electrodes at the vertex (active electrode) and anterior pinna (reference electrode). Six term newborn lambs were tested similarly for ABR comparison. No fetal ABRs appeared before 117 days gestation. Thereafter, the ABRs exhibited decreasing peak latencie

Abstract (sommario):

OBJECTIVE Prenatal closure of myelomeningocele is associated with a reduced rate of hydrocephalus treatment. This need for hydrocephalus treatment is positively correlated with fetal ventricular width. When ventricular width is 15 mm or greater, the benefits of prenatal closure, as a method to decrease hydrocephalus treatment, are reduced. Thus, fetal ventricular size is an important factor when counseling families who are considering intrauterine surgery with mitigation of hydrocephalus as the primary goal. This study sought to determine whether imaging modality (ultrasound [US] vs MRI) and i

Abstract (sommario):

Background Multiple hypertension guidelines recommend out-of-office measurements for the diagnosis of hypertension in non-pregnant adults, whereas pregnancy guidelines recommend in-office blood pressure measurements. The objective of our study was to determine how Canadian Obstetric Medicine and Maternal Fetal Medicine specialists measure blood pressure in pregnancy. Methods An email survey was sent to 69 Canadian Obstetric Medicine and Maternal Fetal Medicine specialists in academic centers across Canada to explore the practice patterns of blood pressure measurement in pregnant women.
