High resolution computed tomography in asthma

High resolution computed tomography in asthma.

OBJECTIVES High-resolution computed tomography (HRCT) can detect the structural abnormalities in asthma. This study attempts to correlate these abnormalities with clinical and pulmonary function test (PFT) data. METHODS Consecutive stable asthma patients attending Mubarak Al Kabeer Hospital, Kuwait, were subjected to HRCT during a six month period from July 2004 to December 2004, after initia...

Thoracic high resolution computed tomography (HRCT) in asthma.

INTRODUCTION High-resolution computed tomography (HRCT) is a widespread medical imaging method for the study of thoracic diseases. In asthma it is very useful particularly when it is difficult to achieve an effective control of disease, and in severe deterioration. AIM It was intended to evaluate the imaging changes by HRCT in asthmatic patients and to assess the expression according to the s...

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...
