3.2 Chest CT features
The characteristics of chest CT were reported in Table 2. During the
hospitalization period, ninety-seven (85%) pediatric patients were
performed no more than two chest CTs, while 17 (15%) cases were
performed 3 or more CT scans. During all the patients, normal chest CTs
were found in 32 (28%) cases, and no more than 2 lobes involved in 63
(55%) cases. Unilateral lung involvement was found in 46 (40%) cases,
and bilateral lung involvement was found in 36 (32%) cases. Bilateral
inferior lobes were most susceptible to COVID-19, with 43 cases (38%)
affected in both the left and right lower lobe, respectively.
Ground-glass opacity (46, 40%) and consolidation (46, 40%) were the
most common lesion patterns (E-figures 2 and 3 for details), while
nodules were found in 7 (6%) cases (E-figure 4 for details). A
comparison of chest CT features between cases with and without
coinfection was shown in E-table 1.
