Acute respiratory distress syndrome (ARDS) is characterized by severe impairment of gas
exchange. Hypoxemia is mainly due to intrapulmonary shunt, whereas increased alveolar …

In patients with the acute respiratory distress syndrome (ARDS), lung imaging is a
fundamental tool in the study of the morphological and mechanistic features of the lungs …

Asthma is a common disease affecting an increasing number of children throughout the
world. In asthma, pulmonary airways narrow in response to contraction of surrounding …

During the past several years there has been extensive development and application of
hyperpolarized helium‐3 (HP 3He) magnetic resonance imaging (MRI) in clinical respiratory …

The assessment of the regional match between alveolar ventilation and perfusion in critically
ill patients requires simultaneous measurements of both parameters. Ideally, assessment of …

This review focuses on the state‐of‐the‐art of the three major classes of gas contrast agents
used in magnetic resonance imaging (MRI)—hyperpolarized (HP) gas, molecular oxygen …

Rationale: The prone position is used to improve gas exchange in patients with acute
respiratory distress syndrome. However, the regional mechanism by which the prone …

The noninvasive assessment of lung function using imaging is increasingly of interest for the
study of lung diseases, including chronic obstructive pulmonary disease (COPD) and …

Over the past few decades, pulmonary imaging technologies have advanced from chest
radiography and nuclear medicine methods to high-spatial-resolution or low-dose chest CT …

Background Fluorine-enhanced MRI is a relatively inexpensive and straightforward
technique that facilitates regional assessments of pulmonary ventilation. In this report, we …
