This demonstrates a MR imaging method to measure the spatial distribution of pulmonary
blood flow in healthy subjects during normoxia (inspired O2, fraction (FIO2)= 0.21) hypoxia …

The temporal dynamics of blood flow in the human lung have been largely unexplored due
to the lack of appropriate technology. Using the magnetic resonance imaging method of …

Specific ventilation imaging was used to identify regions of the healthy lung (6 supine
subjects, ages 21–41 yr, 3 men) that experienced a fall in specific ventilation following …

MRI images of pulmonary blood flow using arterial spin labeling (ASL) measure the delivery
of magnetically tagged blood to an image plane during one systolic ejection period …

When teaching and learning about alveolar ventilation with our class of 300 first-year
medical students, we use four simple, inexpensive “models.” The models, which encourage …

Patients present with a wide range of hypoxemia after acute pulmonary thromboembolism
(APTE). Recent studies using fluorescent microspheres demonstrated that the scattering of …

energy computed tomography acquisitions has entered clinical practice. The purpose of this …

Patients with acute neurologic injuries frequently require mechanical ventilation due to
diminished airway protective reflexes, cardiopulmonary failure secondary to neurologic …

Lung perfusion and ventilation are fundamental biological functions that hold potential as
quantitative biomarkers for advancing our comprehension and management of lung …

Ventilation and perfusion lung imaging continues to be an important technique in the
investigation of lung disease, particularly pulmonary emboli. For the most accurate …
