Learning 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 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 کاملRelationship 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 کاملAssessment of lung area in fetuses with congenital diaphragmatic hernia.
OBJECTIVE To compare the intra- and interobserver agreement of three different methods of measuring lung area in fetuses with congenital diaphragmatic hernia (CDH). METHODS In 71 fetuses with isolated CDH at 21-33 weeks' gestation, the area of the contralateral lung was assessed by firstly, manual tracing of lung borders, secondly, multiplication of the longest diameter of the lung by its wid...
متن کاملComparison of fetal lung area to head circumference ratio with lung volume in the prediction of postnatal outcome in diaphragmatic hernia.
OBJECTIVES To compare prediction of postnatal survival in isolated diaphragmatic hernia by prenatal two-dimensional (2D) versus three-dimensional (3D) sonographic assessment of the contralateral lung. METHODS The lung area to head circumference ratio (LHR) of the contralateral lung was measured and expressed as a percentage of the normal mean for gestation (O/E) in 47 fetuses with isolated di...
