OBJECTIVE To compare the volume of the ipsilateral and contralateral lungs in fetuses with congenital diaphragmatic hernia (CDH). METHODS Left and right lung volumes were measured using three-dimensional (3D) ultrasonography in 42 fetuses with CDH at median 26 (range, 20-32) weeks of gestation. Each value was then expressed as a difference, in standard deviations, from the normal mean for ges...

in this paper we consider several generalizations of the skew t-normal distribution, and some of their properties. also, we represent several theorems for constructing each generalized skew t-normal distribution. next, we illustrate the application of the proposed distribution studying the ratio of two heavy metals, nickel and vanadium, associated with crude oil in shadgan wetland in the south-...

921 April 2015 L UNG ultrasound is a valuable diagnostic modality that allows for rapid assessment of pneumothorax. Compared to chest radiographs, lung ultrasound is more sensitive for pneumothorax.1–3 Presence of lung sliding can be assessed with 2D or M-mode ultrasound and excludes pneumothorax at the intercostal space of the properly orientated ultrasound transducer (fig. A). M-mode displays...

conclusion lesion depth from the pleural surface and the presence of emphysema were strongly correlated with the increasing incidence of pneumothorax after ct-guided pcnb. our results may be applicable for the risk management of pcnbs to reduce pneumothorax as a complication. background previous studies identifying risk factors for pneumothorax in percutaneous core needle lung biopsies reported...
