Chest CT findings were comparable among different convalescent COVID-19 patients
According to the chest CT imaging findings, the lung lesions of 56 patients were divided into glass shadow, stripe, grid shadow, nodular shadow and new lesions. In total, 34 cases (60.7%) were located in the lower right lobe, 36 cases ( 64.3% ) had located in the lower left lobe, 21 cases ( 37.5% ) showed ground-glass shadows, and 25 cases ( 44.6% ) signs of the cord-like changes, 31 cases ( 55.4% ) nodules, and 3 cases ( 5.4% ) mesh shadows. The results of the study found that more than half of the patients had lung lesions, and most of the lesions were located in the lower lungs. The main manifestations are nodular shadows, streaks and ground glass shadows. Most of the severe group has strip-like changes ( 72.2% ) , ground glass shadow ( 61.1% ) , there were nodules ( 60.7% ) and cord-like changes ( 35.7% ) in the moderate group, and most of the mild group had nodules ( 80% ) . Comparing the three groups, the differences in ground glass-like changes ( P=0.038 ) , strip-like changes ( P=0.012 ) , grid shadows ( P=0.035 ) , and nodular shadows ( P=0.043 ) were statistically significant ( Table 6 ) .
