The airflow limitation that defines chronic obstructive pulmonary disease (COPD) is the
result of a prolonged time constant for lung emptying, caused by increased resistance of the …

Magnetic resonance imaging (MRI) of the lung is technically challenging due to the low
proton density and fast signal decay of the lung parenchyma itself. Additional challenges …

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity
and mortality worldwide. COPD is defined by irreversible airflow obstruction. It is a …

MRI has superior soft-tissue definition compared with existing imaging modalities in
radiation oncology; this has the added benefit of functional as well as anatomical imaging …

Oxygen-enhanced MR imaging is a new technique, and its physiological significance has
not yet been fully elucidated. This review article covers (1) the theory of oxygen …

A new method is presented for quantitative mapping of ventilation‐to‐perfusion ratios (VA/Q)
in the lung: MRI of the 19F longitudinal relaxation time (T1) of an inert fluorinated gas at …

Purpose: Oxygen-enhanced magnetic resonance (MR)-ventilation imaging of the lung is
based on the inhalation of a high concentration of oxygen (hyperoxia). However, the effect of …

Purpose To evaluate oxygen-enhanced T1-mapping magnetic resonance (MR) imaging of
the lungs for detection of chronic lung allograft dysfunction (CLAD) in patients who have …

In recent years, magnetic resonance (MR) imaging, a noninvasive imaging modality, has
been receiving a lot of attention and is particularly attractive for children, mainly because …

Since thoracic MR imaging was first used in a clinical setting, it has been suggested that MR
imaging has limited clinical utility for thoracic diseases, especially lung diseases, in …
