Objective. Ultrasound lung comets (ULCs) now have an acknowledged correlation with extravascular lung water, but they present in different orders and numbers in different pathologic pulmonary entities. How these artifacts are created is not yet known, and the literature gives discordant hypotheses. Understanding their formation is the first step in understanding lung disease. The purpose of this study was to show the morphologic and genetic variability of interstitial lung disease studied with echography and thus to propose a unitary mechanism for the formation of ULCs. Methods. This study included 3 parts: (1) a retrospective analysis of echographic lung images of patients with interstitial syndrome; (2) an analysis of the literature for definitions of the size of the pulmonary lobule; and (3) an experimental model of different air-water interfaces scanned with varying ultrasonic frequencies.Results. The retrospective analysis of echographic lung images included 176 patients with diffuse ULCs: 118 patients had acute pulmonary edema; 18 had acute lung injury/acute respiratory distress syndrome; and 40 were premature neonates with respiratory distress syndrome. Experimental models permitted us to discover that ring-down artifacts are produced only by single and double layers of bubbles in specific structural settings. Conclusions. Reverberation between bubbles with a critical radius seems to be at the origin of ring-down artifacts. Echographic manifestations of interstitial lung disease, whose genesis lies in the partial air loss of lobes and segments, are acoustic phenomena originating from variations in the tissue-fluid relationship of the lung. A correlation between anatomopathologic characteristics and structures of sonographic artifacts could allow more rapid and noninvasive diagnoses.

“…Study included four patients of emphysema of which three cases showed centrilobular emphysema characterised by bilateral multiple small centrilobular lucencies with ill-defined walls scattered through out the lungs in according to findings of Stern EJ and Frank MS, Webb WR et al and Murata K et al [15][16][17] Paraseptal emphysema was identified in one case.…”

O objetivo deste novo consenso brasileiro é atualizar e dar continuidade à padronização da terminologia dos principais descritores e padrões fundamentais da TC de tórax em língua portuguesa. Este consenso contém uma descrição sucinta dos principais termos utilizados na TC de tórax e ilustrações de exemplos clássicos. O grupo de autores é formado por médicos radiologistas membros do Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, especializados em radiologia torácica, e por pneumologistas membros da Sociedade Brasileira de Pneumologia e Tisiologia, com particular interesse em diagnóstico por imagem.
