[The role of radio-imaging techniques in the investigation of the pathophysiologic mechanisms in chronic obstructive bronchopneumonia. Part I. Role of imaging in the investigation of respiratory lesions caused by COPD].

摘要: Chronic obstructive pulmonary disease (COPD) is a common (4-6% of adults), with insidious onset and slow progression, which why the remains under diagnosed especially in early stages. Most patients get medical attention stage III, IV disease, according to GOLD classification (Global Obstructive Lung Diseases). According GOLD, priority staging severity evaluation respiratory function, FEV1. However radiographic risk (smokers or those working polluted environment) may represent first step marking changes lung comorbidities. Since this causing disability major socioeconomic problem, modern investigations, such as spiral computerised tomography (CT), multidetector (MDCT) magnetic resonance (MRI) be alternatives diagnosis detection disease.
