Hypersensitivity Pneumonitis with Normal High Resolution Computed Tomography Scans

High-resolution computed tomography and histopathological findings in hypersensitivity pneumonitis: a pictorial essay*

Hypersensitivity pneumonitis is a diffuse interstitial and granulomatous lung disease caused by the inhalation of any one of a number of antigens. The objective of this study was to illustrate the spectrum of abnormalities in high-resolution computed tomography and histopathological findings related to hypersensitivity pneumonitis. We retrospectively evaluated patients who had been diagnosed wi...

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...

False-positive MIBG scans with normal computed tomography imaging in patients with high-risk neuroblastoma.

TO THE EDITOR: Kushner et al investigate the most sensitive modality for early detection of relapse in patients with asymptomatic high-risk neuroblastoma who had previously achieved complete remission or very good partial remission. They demonstrate that iodine123 (I) metaiodobenzylguanidine (MIBG) scanning was the only positive surveillance scan in 27% of patients and conclude that IMIBG scann...
