[The contribution of radioimaging to the understanding of the pathophysiological mechanisms of chronic obstructive pulmonary diseases (COPD). Part II. Contribution of imaging in the investigation of comorbidities associated with COPD: cardiovascular diseases, lung cancer, skeletal muscle and nervous

Among the diseases frequently associated with the chronic obstructive pulmonary disease (COPD) count the pulmonary neoplasm, severe cardiovascular diseases, muscle wasting, osteoporosis, diabetes mellitus etc. These conditions are often diagnosed when already in an advanced stage, although their presence may seriously affect the patient's quality of life and prognostic. Under certain circumstances the early usage of imagistic techniques in addition to the pulmonary functional tests leads not only to the early adopting of an adequate treatment that considers the comorbidity, but offers also a better understanding of the COPD's physiopathology, of its--and of the associated diseases' evolution.
