[ value of computed tomography in the diagnosis and staging of bronchiectasis]

ABSTRACT

Basing themselves on literature data, the authors specify the tomodensitometric semiology of bronchiectasis and locate the place of the computed tomography [C.T] in the diagnosis and staging of bronchiectasis in comparison with standard chest radiograph and bronchography They notice the advantages and limits of each method of examination The C.T, as non invasive examination which revolutionized the medical imaging in the last years, intervenes at all the stages of diagnosis of bronchiectasis. Recognition morphologic type, extension and associated damages. But technical Conditions are indispensable, as achievement of thin-section C.T, Judicious choice of windows with use of wide "bronchic" Window and apparatus with high Space resolution. At present, the choice between C.T and bronchograpy in the diagnosis of bronchiectasis seems to depend on quality of tomodensitometric images, localized or diffuse bronchiectasis and degree of Clinical suspicion The C.T of thorax must be done at any suspicion of bronchiectasis and only after the study of its results will be established the management. It seems that bronchography has no more to be indicated at first intention, but it restes indicated in case of discordance between a very suggestive symptomatology and a doubtful C.T. and in case of limited but complicated bronchiectasis which can undergo surgical operation
