High-resolution computed tomography of the lungs in pediatric patients

Use of high resolution computed tomography of the lungs in patients with rheumatoid arthritis.

OBJECTIVE To assess the usefulness of high resolution computed tomography (HRCT) of the lungs in patients with rheumatoid arthritis (RA) with and without respiratory symptoms. PATIENTS AND METHODS Eighty eight RA patients with a mean duration of disease 12 (SD 8) years were evaluated. Eleven patients were excluded because of previous exposure to silica. The 77 remaining patients formed two gr...

Pulmonary function tests and high resolution computed tomography of the lungs in patients with rheumatoid arthritis.

OBJECTIVE To compare the results of pulmonary function tests (PFTs) and high resolution computed tomography (HRCT) of the lungs in rheumatoid arthritis (RA) patients. METHODS Sixty eight patients (54 women, 14 men) fulfilling the revised criteria for RA were consecutively included in a transversal prospective study. Their mean age was 58.8 years (range: 35-82) and the mean duration of the dis...

High-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...
