| 目的探讨新型冠状病毒肺炎( COVID-19)发病早期、进展期、转归期的胸部 CT影像学动态变化与临床分型及表现的关系。方法收集重庆大学附属三峡医院 2020年 1—2月 88例治愈出院 COVID-19病人的临床与影像学资料，其中出院诊断普通型 51例，重型 29例，危重型 8例。每例病人做了( 4±1)CT检查，范围为 3~6次，每次检查间隔 3~7 d，总共 346次胸部 CT。回顾性分析每例病人发病早期( 1~7 d)、进展期( 8~14 d)、转归期( >14 d)胸部 CT影像学表现及变化。采用 Kruskal-Wallis秩和检验(非正态分布)比较普通型、重型、危重型病人的年龄、发病至影像学好转天数、发病至出院天数差异。结果 COVID-19发病早期 CT主要表现为双肺多叶多段( 74/88，84%)、斑片状磨玻璃影( 82/88，93%)，以外带及胸膜下分布为主( 374/492，76%)；进展期双肺磨玻璃病灶逐渐增多、增大，密度增高，边缘变清晰，其内纹理增多、间质增厚，常出现“铺路石”征( 29/88，33%)和“蜘蛛网”征( 26/88，30%)，斑片状实变影及条索影增多；转归期双肺磨玻璃及实变病灶逐渐吸收、减少， 95%(84/88)的病人出院时双肺残留条索影、浅淡磨玻璃影或条网状间质纤维化病灶。普通型、重型、危重型病人的年龄中位数(四分位数间距)分别为 47(7)、 49(13)、 69(20)岁，发病至影像学好转天数分别为 13(6)、 17(3)、 24(9)d，发病至出院天数分别为 18(5)、23(4)、29(4) d，三者均 P<0.001。结论胸部 CT可以很好地观察 COVID-19病人发病早期、进展期、转归期的影像学动态变化， COVID-19病人临床分型的严重程度与病人年龄、影像学及临床好转天数存在相关性。 |

| Objective To investigate the relationship between the dynamic changes of chest CT imaging in the early stage, progres.sive stage and prognosis stage of Corona Virus Disease 2019 (COVID-19) and its clinical classification and manifestation.Methods Clinical and imaging data of 88 cured and discharged COVID-19 patients in Chongqing University Three Gorges Hospital from Januaryto February 2020 were collected. Among them, 51 cases were diagnosed as normal type, 29 cases as heavy type and 8 cases as criticaltype. Each patient underwent (4±1) CT examinations ranging from 3 to 6 times, intervals of 3 to 7 days. There were a total of 346 chestCT scans. The chest imaging findings and changes of each patient in the early onset (1-7 d), progressive period (8-14 d), and transitionperiod (> 14 d) were retrospectively analyzed. The different in age, days of image improvement and days of discharge of normal, severeand critical type patients by Kruskal-Wallis rank sum test (non-normal distribution) were compared.Results In the early stage of CO. VID-19, CT mainly showed patchy ground glass opacity (82/88, 93%), in multiple lobes and segments of both lungs (74/88, 84%), main.ly in the outer zone and subpleural distribution (374/492, 76%). In progressive phase, ground glass lesions in both lungs gradually in.creased and enlarged, increased density, increased texture inside, interstitial thickening, "paving stone" sign (29/88, 33%) and "spiderweb" sign (26/88, 30%) often appear, patchy consolidation and cableway shadows increased. At discharge, 95% (84/88) patients had re.sidual stripe shadows, light ground glass opacity, or reticular interstitial fibrosis lesions in both lungs. The median age (quartile spac.ing) of patients with normal type, severe type and critical type were 47 (7), 49 (13) and 69 (20) years old, respectively. The days from on.set to radiological improvement were 13 (6), 17 (3) and 24 (9) d, respectively. The days from onset to discharge were 18 (5), 23 (4) and29 (4) d, respectively. P values of all three were < 0.001.Conclusions Chest CT can well observe the dynamic changes of imaging in the early, progression and recurrent stages of COVID-19 patients. The severity of clinical classification of COVID-19 patients is corre. lated with age, days of imaging and clinical improvement. |
