With the fetal stomach utilized as a general marker, targeted-imaging of the fetal abdomen was initiated to locate the pancreas. Overall, the pancreas was seen in 77 of 149 cases (51.7%). Menstrual age and the position of the fetus were significant factors in determining the frequency of pancreatic visualization.
The transverse cerebellar diameter was obtained in 44 small for gestational age (SGA) fetuses between 27-42.8 weeks. Twenty-nine of 44 fetuses had antepartum and/or neonatal complications consistent with intrauterine growth retardation. The cerebellar diameter was normal in 12 (27.3%), between 1-2 SDs below the mean for gestational age in six (13.6%), and(More)
Cerebellar hypoplasia is a consistent finding in necropsy studies of children and adults affected by Down syndrome. The transverse cerebellar diameter was measured in 23 second-trimester fetuses with Down syndrome. All the measurements were within the normal range for gestational age.
OBJECTIVE To review our experience with antenatal detection and subsequent neonatal outcome of fetuses with a persistent right umbilical vein. METHODS In a prospective observational study, 33 cases of persistent right umbilical vein were detected during 15,237 obstetric ultrasound examinations performed after 15 weeks' gestation. RESULTS Persistent(More)
Sonologists should be familiar with the frequency of resolution and the ultrasonic appearance of the normal fetal azygous vein. In this study, 66 consecutive uncomplicated pregnancies were scanned to determine the frequency of imaging the fetal thoracic azygous vein. Between 21.7 and 30 gestational weeks, the azygous vein could be imaged in 50% of the cases(More)
OBJECTIVE To review our experience with the antenatal detection and subsequent neonatal outcome of fetuses with a pelvic kidney. METHODS A retrospective review of 25,551 obstetric ultrasound examinations performed after 16 weeks' gestation identified 13 cases of fetal pelvic kidneys (one per 1965 examinations). RESULTS Three pelvic kidneys were(More)
The transverse cerebellar diameter was measured in 19 fetuses with trisomy 18. Eleven of the cerebellar measurements (57.9%) were greater than 2 SD below the mean for the patient's gestational age. If fetal biometry rather than last menstrual period were used to determine gestational age, four of the 19 (21.0%) cerebellar measurements were greater than 2 SD(More)
Intrauterine growth retardation (IUGR) is associated with an increase in perinatal mortality as well as long-term neurobehavioral morbidity. Despite the increasing sophistication of antenatal fetal assessment, the diagnosis of growth retardation remains difficult. Since the fetal effects of growth inhibition are variable, no one ultrasonic parameter can(More)
