INTRODUCTION: Cleft palate is one of the major facial congenital malformation in newborns. Pre-natal detection of this malformation is limited to detection of clefting of hard palate but isolated soft palate clefting still remains challenge for sonologists. As Indian literature is limited present study was attempted to provide dimensions and position of fetal palate by digitized images. AIM: To study dimensions, position and differences in parameters between second and third trimester fetuses...

Our unit has been providing antenatal consultations for 30 years following the discovery of limb malformation with the fetus. Each of these consultations is specific and carried out by a multi-professional team. It requires a physical and rehabilitation doctor, an orthopedic surgeon, an occupational therapist for upper limb malformation, a physiotherapist for lower malformation and a psychologist. This multidisciplinary consultation is unique because of each pregnancy story, because of each patient life story but also because of the words used by the sonologist when announcing the diagnosis...

Various approaches to 2-dimensional speckle tracking have been used to evaluate left ventricular function and deformation in the fetus, child, and adult. In 2015, because of differences in imaging devices and analytical programs, the cardiology community published a consensus document proposing standards for pediatric/adult deformation imaging using 2-dimensional speckle tracking. The understanding and application of deformation imaging in the fetus have been limited by a lack of uniform software, terminology, techniques, and display...

Lami Yeo, Roberto Romero
The effective performance of fetal cardiac examination using spatiotemporal image correlation (STIC) technology requires 2 essential steps: volume acquisition and postprocessing. An important prerequisite is training sonologists to acquire high-quality volume data sets so that when analyzed, such volumes are informative. This article is part 2 of a series on 4-dimensional sonography with STIC. Part 1 focused on STIC technology and its features, the importance of operator training/experience and acquisition of high-quality STIC volumes, factors that affect STIC volume acquisition rates, and general recommendations on performing 4D sonography with STIC...

The occurrence of congenital neuroblastoma presenting at birth with symptoms of epidural compression secondary to spinal canal invasion is rare. Almost all cases reported in the literature have survived from the tumor but suffer severe sequelae, with the exception of the 2 most recently described whose birth was anticipated. The 3 cases of this article have been followed for a minimum of 5 years with the aim to describe their definitive late complications. In none of these cases had the routine ultrasound scan performed in third trimester of pregnancy discovered a tumor mass, nor had it shown abnormal fetal movements...

BACKGROUND: The high incidence of IUGR and its low recognition lead to increasing perinatal morbidity and mortality for which prediction of IUGR with timely management decisions is of paramount importance. Many studies have compared the efficacy of several gestational age independent parameters and found that TCD/AC is a better predictor of asymmetric IUGR. AIM: To compare the accuracy of transcerebellar diameter/abdominal circumference with head circumference/abdominal circumference in predicting asymmetric intrauterine growth retardation after 20 weeks of gestation...

OBJECTIVES: The true optic nerve sheath diameter cutoff value for detecting elevated intracranial pressure is variable. The variability may stem from the technique used to acquire sonographic measurements of the optic nerve sheath diameter as well as sonographic artifacts inherent to the technique. The purpose of this study was to compare the traditional visual axis technique to an infraorbital coronal axis technique for assessing the optic nerve sheath diameter using a high-frequency linear array transducer...
