OBJECTIVE: The aim of the study is to assess the relationship between uteroplacental Doppler sonography findings and cerebral diffusion measured by diffusion-weighted magnetic resonance imaging (DWI) in fetuses with early- onset intrauterine growth restriction (IUGR). MATERIAL AND METHODS: The study included 54 pregnant women with fetal IUGR and 15 healthy controls (n: 15). Fetuses with IUGR were classified into 4 groups based on Doppler findings: group 1 (n = 12), umbilical artery (UA) pulsatility index (PI) >95pc; group 2 (n = 11), UA PI > 95 pc and middle cerebral artery PI <5pc; group 3 (n = 21), absent end-diastolic (A-EDF) in UA; group 4 (n = 10), reversed EDF in UA...

BACKGROUND: Doppler indices form an integral component of noninvasive evaluation of fetal well-being. There is paucity of information about normal obstetric Doppler indices, particularly from the Indian subcontinent. The aim of the study was to find the values of pulsatility index (PI), resistive index (RI) of umbilical artery (UA), and fetal middle cerebral artery (MCA) and calculate cerebro-placental ratio (CP ratio) for 18-40 weeks of normal gestation so that a reference range of these Doppler values can be postulated...

BACKGROUND: Fetal growth restriction (FGR) is associated with an increased risk of adverse perinatal outcome (APO). However, distinguishing this condition from smallness-for-gestational age remains elusive. A set of criteria has recently been proposed for such purpose, including the severity of smallness, Doppler parameters and growth velocity. OBJECTIVES: To establish whether the use of growth velocity adds to Doppler evaluation in predicting APO among SGA-suspected fetuses...

Fetuses with pulmonary atresia or pulmonary stenosis with intact ventricular septum manifest variable degrees of right ventricle hypoplasia and inadequacy. We studied the relationship between prenatal echocardiographic parameters and their progression through gestation as potential predictors of postnatal single-ventricle or two-ventricle care strategy. Serial fetal echocardiograms of pulmonary atresia (n = 28) or severe pulmonary stenosis (n = 8) and intact ventricular septum were reviewed. Measurements included tricuspid valve and mitral valve diameter and Z scores, degree of tricuspid regurgitation, presence of subaortic stenosis, presence of coronary artery fistulae, and Doppler pulsatility indices in middle cerebral and umbilical artery...

One dimensional Doppler Ultrasound (DUS) is a low cost method for fetal auscultation. However, accuracy of any metrics derived from the DUS signals depends on their quality, which relies heavily on operator skills. In low resource settings, where skill levels are sparse, it is important for the device to provide real time signal quality feedback to allow the re-recording of data. Retrospectively, signal quality assessment can help remove low quality recordings when processing large amounts of data. To this end, we proposed a novel template-based method, to assess DUS signal quality...

BACKGROUND: The use of neonatal 3-lead electrocardiograms (Neo-ECG) is suggested as a method for the assessment of heart rate (HR) in neonatal resuscitation, but primary childbirth facilities (i.e., maternity clinics or maternity homes) are not sufficiently equipped for this. The objective of this study was to confirm the potential of using a handheld fetal Doppler device (FDD), widely used to assess HR in labor room resuscitation, and to compare its equivalency to Neo-ECG. METHODS: In low-risk full-term infants, HR was measured 5 times/minute in minutes 1-5 postpartum using the FDD and Neo-ECG, and their equivalence was compared...
