Regional lung function and heterogeneity of specific gas volume in healthy and emphysematous subjects.
The aim of our study was to study regional lung function by standard computed tomography (CT) and characterise regional variations of density and specific gas volume (SVg) between different lung volumes. We studied 10 healthy and 10 severely emphysematous subjects. Corresponding CT images taken at high and low lung volumes were registered by optical flow to obtain two-dimensional maps of pixel-...

To study regional lung function by standard CT and characterize regional variations of density and specific gas volume (SVg) between different lung volumes, we studied 10 healthy and 10 severe emphysematous subjects. Correspondent CT images taken at high and low lung volumes were registered by optical flow to obtain 2-D maps of pixel-by-pixel differences of density (HU) and SVg (SVg) at slice...
متن کاملReversible volume changes of trapped gas in nonspecific bronchoprovocation tests.
Thirty patients with a history of asthma and ten patients with suspected bronchial hyperreactivity underwent nonspecific provocation testing. The control group consisted of ten normal volunteers without a history of lung disease. The patients' baseline FEV1 (percent predicted) revealed mild obstructive disease (72.9 +/- 8.9 percent and 74.6 +/- 7.7 percent) compared with controls (87.2 +/- 8.5 ...
متن کاملAge Specific Reference Levels of Serum Prostate-Specific Antigen, Prostate Volume and Prostate Specific Antigen Density in Healthy Iranian Men
Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...
متن کاملChanges in Bacterial Volume as the Result of Specific Agglutination
Measurements indicate that bacterial antigens increase in volume as the result of specific agglutination. There is a general parallelism between the increase in antigenic volume and the concentration of the immune serum. The phenomenon is specific. There is no increase with normal serum; with absorbed serum the increase is slight and it can be correlated with the presence of unabsorbed antibody...
