“…Their low costs, well-established correlation with clinical profile, reproducibility of results, the ability to predict prognosis and non-utilization of ionization radiation give PFTs an advantage over the other methods [22]. However, there are several studies that show that PFTs have limitations especially in patients with less severe emphysema.…”

SummaryPulmonary emphysema, together with chronic bronchitis is a part of chronic obstructive pulmonary disease (COPD), which is one of the leading causes of death in the United States and worldwide. There are many methods to diagnose emphysema. Unfortunately many of them, for example pulmonary function tests (PFTs), clinical signs and conventional radiology are able to detect emphysema usually in its late stages when a great portion of lung parenchyma has been already destroyed by the disease. Computed tomography (CT) allows for early detection of emphysema. CT also makes it possible to quantify the total amount of emphysema in the lungs which is important in order to precisely estimate the severity of the disease. Those abilities of CT are important in monitoring the course of the disease and in attempts to prevent its further progression. In this review we discuss currently available methods for imaging emphysema with emphasis on the quantitative assessment of emphysema. To date, quantitative methods have not been widely used clinically, however, the initial results of several research studies regarding this subject are very encouraging.

“…Thin collimation and contrast may affect the absolute attenuation numbers when a single slice is analyzed. However, with densitometry applied to the total lung volume, the quantitative assessment of emphysema is not affected [22,32]. …”

“…These findings are laminar atelectasis, mostly posterior and basal, located in the dependent regions of the lungs ( Figure 5); subpleural linear thickening ( Figure 6); areas of air trapping ( Figure 7); bronchial thickening and ectasia ( Figure 8); and lung cysts. (41,(50)(51)(52)(53) The differential diagnosis between normal, aging-related imaging findings and imaging findings secondary to disease is quite difficult, and it is often impossible to distinguish between the two types of findings using imaging tests alone. Monitoring these lesions is often necessary, and comparison with previous tests is indispensable.…”

In the elderly (conventionally defined as individuals ≥ 60 years of age), it is often difficult to establish what normality is, because of the numerous anatomical and physiological modifications that occur during the aging process. As a result, the greatest challenge is to differentiate between the normal aging process and the onset of disease. Healthy elderly people commonly present borderline findings on chest imaging. We systematically reviewed the medical literature on the subject, covering the period between 1950 and 2011, including articles in Portuguese, English, French, Italian, and Spanish. We searched the PubMed, LILACS, and SciELO databases, using the search terms "age", "aging", "lung", "thorax", "chest", "X-ray", "radiography", "pulmonary", and "computed tomography"-as well as their corresponding translations-in various combinations. We included only original or review articles on aging-related chest imaging findings. In broad terms, aging results in physiological modifications that must be recognized so as not to be erroneously interpreted as pathological.Keywords: Aging; Thorax; Lung; Diagnostic imaging. ResumoNos idosos (convencionalmente definidos como indivíduos com idade ≥ de 60 anos), é muitas vezes difícil estabelecer o que é normal devido a inúmeras modificações anatômicas e fisiológicas que ocorrem durante o processo de envelhecimento. Como resultado, o principal problema consiste em diferenciar o ponto em que o envelhecimento é normal daquele no qual a doença começa. Os achados radiológicos do tórax de pessoas idosas sadias são comumente limítrofes. Revisamos sistematicamente a literatura médica sobre o assunto, abrangendo o período entre 1950 e 2011, incluindo artigos em português, inglês, francês, italiano e espanhol. A busca foi feita através das bases de dados PubMed, LILACS e SciELO, utilizando os seguintes termos: age, aging, lung, thorax, chest, X-ray, radiography, pulmonary, computed tomography e suas traduções correspondentes, em combinações variadas. Os critérios de inclusão foram artigos originais e de revisão de achados radiológicos no tórax relacionados ao envelhecimento. Em linhas gerais, o envelhecimento resulta em modificações fisiológicas que devem ser reconhecidas de forma a não serem erroneamente interpretadas como patologias.Descritores: Envelhecimento; Tórax; Pulmão; Diagnóstico por imagem.* Study carried out at the
