CT Features of Coronavirus Disease 2019 (COVID-19) Pneumonia in 62 Patients in Wuhan, China.

摘要: OBJECTIVE. The purpose of this study was to investigate 62 subjects in Wuhan, China, with laboratory-confirmed coronavirus disease (COVID-19) pneumonia and describe the CT features epidemic disease. MATERIALS AND METHODS. A retrospective consecutive patients COVID-19 performed. images clinical data were reviewed. Two thoracic radiologists evaluated distribution signs lesions also scored extent involvement signs. Mann-Whitney U test used compare lesion scores. chi-square early-phase versus advanced-phase pneumonia. RESULTS. total (39 men 23 women; mean [± SD] age, 52.8 ± 12.2 years; range, 30-77 years) evaluated. Twenty-four 30 who underwent routine blood tests (80.0%) had a decreased lymphocyte count. Of 27 their erythrocyte sedimentation rate high-sensitivity C-reactive protein level assessed, 18 (66.7%) an increased rate, all (100.0%) elevated level. Multiple seen on initial scan 52 (83.9%). Forty-eight (77.4%) predominantly peripheral lesions. score for upper zone (3.0 3.4) significantly lower than that middle (4.5 3.8) 3.7) zones (p = 0.022 p 0.020, respectively), there no significant difference 1.00). anterior area (4.4 4.1) posterior (7.7 6.3) 0.003). findings as follows: 25 (40.3%) ground-glass opacities (GGO), 21 (33.9%), consolidation; 39 (62.9%), GGO plus reticular pattern; 34 (54.8%), vacuolar sign; 28 (45.2%), microvascular dilation 35 (56.5%), fibrotic streaks; subpleural line; 33 (53.2%), transparent line. With regard bronchial changes CT, 45 (72.6%) air bronchogram, 11 (17.7%) bronchus distortion. In terms pleural changes, showed (48.4%) thickening, (56.5%) retraction sign, six (9.7%) effusion. Compared (≤ 7 days after onset symptoms), (8-14 symptoms) characterized by frequencies pattern, streaks, line, distortion, effusion; however, CONCLUSION. examination mixed diverse pattern both lung parenchyma interstitium involved. Identification single suggested aggravation repair coexisted Lesions presented characteristic multifocal regions area. count most common laboratory findings.
