Abstract

HRCT uses high spatial resolution of lung parenchyma, using thin collimation, high-spatial frequency reconstruction algorithm, increased kVp and mA settings.. Alterations in anatomy can be identified at level of secondary pulmonary lobule which can be diagnostic, although nonspecific. High-resolution CT scanning is helpful in identifying patients who have significant lung disease despite a normal chest radiograph. The aim of our present study is to summarize clinical usefulness of HRCT in patients with Chronic Lung Disease, and suggest specific indications based on a review of literature. The clinical value of HRCT is assessed in terms of its ability to detect diffuse chronic lung disease, confirm or refute presence of abnormality when chest radiograph is normal and its ability to determine optimal site of lung biopsy
