title: Thoracic imaging--then and now.
abstract: The chest radiograph has proved a robust diagnostic aid over the last century. The accumulation of knowledge about chest disease by radiography has been gained slowly during the last 90 years. New impetus has been given by the development of computed tomography and the recent refinements of high resolution and spiral computed tomography. The pathophysiological insights provided by these new techniques have been obtained in a remarkably short period, with the promise of more to come.
