High-resolution computed tomography in assessment of patients with emphysema.
OBJECTIVE To assess whether high-resolution computed tomography (HRCT) variables are as good as other known clinical variables in grading emphysema patients. METHODS A detailed clinical history was taken and physical examination performed. We performed serum study, lung function testing, and HRCT scanning to assess emphysema. Mean lung density, the attenuation value separating the least 15% o...
متن کاملHigh-resolution computed tomography
This paper investigates high-resolution reconstructions from eeciently sampled data in parallel-beam tomography, in particular local tomography. A class of sampling schemes is deened and characterized, and it is shown that the standard scheme and the interlaced scheme of Cormack are most promising. An error analysis for the ltered backprojection algorithm for both global and local tomography is...
متن کاملEmphysema findings associated with heavy asbestos-exposure in high resolution computed tomography of finnish construction workers.
Asbestos fibers are known to cause lung fibrosis, but their role in emphysema is unclear. We wanted to evaluate the relationship between asbestos exposure and emphysema by using high-resolution computed tomography (HRCT). Conventional and high resolution CT was performed on 600 smoking construction workers with an asbestos-related occupational disease. Emphysema subtypes (centrilobular, parasep...
