Cost-benefit evaluation of HRCT.
HRCT permits visualization of the secondary pulmonary lobule. The technique of HRCT, and the anatomy of the lung structure are discussed. The patterns and distribution of disease, and diagnosis of many diffuse lung diseases are also discussed. Finally biological, economic and clinical aspects of HRCT are evaluated: a) the dose administered is comparable with the dose administered with chest radiography; b) HRCT examination does not cost more than CT examination (about 100 dollars); c) HRCT is useful in the detection, evaluation and diagnosis of diffuse lung diseases, such as acute or chronic interstitial disease, emphysema and bronchiectasis, both in paediatric, adult and elderly patients.
