Long-term CT abnormalities in lung images were common up to 1 year or even more after COVID-19 pneumonia, shows a recent study published in the journal Radiology. The secondary analysis of CovILD, a prospective, multicenter, observational cohort study by Dr Christoph Schwabl and colleagues from the Department of Radiology at the Medical University of Innsbruck in Austria from April to August 2020, evaluated pulmonary abnormalities on chest CT at 2, 3 and 6 months and 1 year after COVID-19 symptoms in 142 adults who had mild to severe COVID-19. It found that at least 54 percent among the participants had CT abnormalities 1 year later, 34 percent had subtle subpleural reticulation, ground-glass opacities or both and 20 percent had extensive ground-glass opacities, reticulations, bronchial dilation and/or microcystic changes in the lung.
