Imaging of the lungs in patients with asthma has evolved dramatically over the last decade
with sophisticated techniques, such as computed tomography, magnetic resonance imaging …

The aging process involves the human lung, with loss of lung volume, decline in FEV 1, and
reduced gas exchange. There is also the development of decreased lung density …

Global measurements of the lung provided by standard pulmonary function tests do not give
insight into the regional basis of lung function and lung disease. Advances in imaging …

Computed tomography was used to determine the vertical gradient of physical density in
peripheral lung tissue of 12 healthy supine subjects, at total lung capacity and residual …

Computed tomography (CT) was first developed to measure accurately radiographic density,
rather than as a method of imaging. 19 Although subsequent development concentrated on …

Awide VARIETY of diseases result in diffuse cystic abnormalities within the lungs. 1~ 2
Despite the well-established role of chest roentgenography to accurately and inexpensively …

Lung density for assessment of hydration status in hemodialysis patients using the
computed tomographic densitometry technique. The density of the lung reflects the total …

RATIONALE AND OBJECTIVES.: Pulmonary hypertension may complicate systemic
sclerosis in the absence of fibrosing alveolitis. Abnormal pulmonary perfusion is known to …

Increased or decreased pulmonary blood flow (PBF) and an increased pulmonary vascular
resistance (PVR), represent common and important change in pulmonary hemodynamics. In …

In 10 hemodialysis patients, with an ultrafiltration volume ranging from 1 to 4.5 liters per
session, the lung density was measured by computed tomography (CT) and the lung …
