Relationship between lung-to-head ratio and lung volume in normal fetuses and fetuses with diaphragmatic hernia.
OBJECTIVE To examine the relationship between the fetal lung area and lung area to head circumference ratio (LHR) and lung volume by three-dimensional (3D) ultrasonography in normal fetuses and in fetuses with unilateral congenital diaphragmatic hernia (CDH). METHODS In 64 fetuses with CDH at median 26 (range, 20-32) weeks of gestation the contralateral lung volume, lung area and LHR were mea...
متن کاملLearning curve for lung area to head circumference ratio measurement in fetuses with congenital diaphragmatic hernia.
OBJECTIVE To assess the learning curve for the fetal lung area to head circumference ratio (LHR) calculation in fetuses with congenital diaphragmatic hernia (CDH). METHODS Three trainees with the theoretical knowledge, but without prior experience in the LHR measurement, were selected. Each trainee and one experienced examiner measured the observed to expected (O/E)-LHR in the lung contralate...
متن کاملAre ethnic differences in lung function explained by chest size?
BACKGROUND Ethnic differences in lung function (LF) are recognised in adults and children. Most prediction equations for LF are derived from whites, so non-whites are at risk of erroneous assessment. It was hypothesised that differences in chest dimensions would explain differences in LF between Asian (Indian) and white schoolchildren. AIMS To quantify the impact of chest dimensions on LF, wh...
متن کاملObserved to expected lung area to head circumference ratio in the prediction of survival in fetuses with isolated diaphragmatic hernia.
OBJECTIVE To assess the value of antenatally determined observed to expected fetal lung area to head circumference ratio (LHR) in the prediction of postnatal survival in isolated, congenital diaphragmatic hernia (CDH). METHODS Two groups of fetuses were examined. The first group included 650 normal fetuses at 12-32 weeks' gestation, and the data collected were used to establish a normal range...
متن کاملLung and heart volumes by three-dimensional ultrasound in normal fetuses at 12-32 weeks' gestation.
OBJECTIVE To establish reference intervals for the fetal right, left and total lung volumes and heart volume between 12 and 32 weeks of gestation. METHODS Fetal lung and heart volumes were measured using three-dimensional (3D) ultrasound in 650 normal singleton pregnancies at 12-32 weeks. The VOCAL (Virtual Organ Computer-aided AnaLysis) technique was used to obtain a sequence of six sections...
