Mosaic attenuation is a descriptive term used in describing a patchwork of regions of differing pulmonary attenuation on CT imaging. parenchymal disease: considered most common cause of mosaic attenuation; high attenuation regions are abnormal and represent ground-glass opacity.Click to see full answer. Regarding this, what causes mosaic attenuation?Mosaic attenuation can be an indirect sign of small airways disease on inspiratory CT. Although small airways disease is the most common cause of mosaic attenuation where the hyperlucent lung is abnormal, disease of the pulmonary vasculature can lead to a similar appearance.Furthermore, what is Mosaic lung? Mosaic attenuation is a CT pattern defined by the Fleischner Society glossary as a. “patchwork of regions of differing attenuation seen on CT of the lungs.” It is. characterized by heterogeneous lung attenuation with well-defined borders cor- responding to the secondary pulmonary lobules. Secondly, what is mild mosaic attenuation? MOSAIC ATTENUATION. Mosaic perfusion refers to areas of decreased attenuation which results from regional differences in lung perfusion secondary to airway disease or pulmonary vascular disease.What causes air trapping in the lungs?When found in isolation, chronic bronchitis, asthma, bronchiolitis obliterans, and unspecified small airways disease were the most common causes of air trapping. Unusual conditions causing isolated air trapping included vasculitis and diffuse idiopathic neuroendocrine cell hyperplasia.
