摘　　要：目的探讨普通型新型冠状病毒肺炎(COVID-19)的CT影像特点与临床表现的关系。方法回顾性分析92例普通型COVID-19患者的临床和CT资料。结果92例患者中,有75例(81.5%)出现临床症状,以干咳和发热为主;有68例(73.9%)出现肺炎影像征象且均表现磨玻璃密度影(GGO)。发热症状与CT影像多发病灶、GGO伴实变、最大斑片影长度、空气支气管征呈正相关(r分别0.312、0.269、0.364、0.385,P<0.05),而咳嗽与胸膜下条索影征象呈负相关(r=-0.293,P<0.05)。结论普通型COVID-19的CT影像有特征性表现,CT对于无症状或轻微COVID-19病例诊断有重要意义。Objective To explore the relationship between CT imaging characteristics and clinical manifestations in ordinary COVID-19.Methods Clinical and CT imaging data of 92 patients with ordinary COVID-19 were retrospectively analyzed.Results Among 92 cases,clinical symptoms including dry cough and fever occurred in 75(81.5%),while imaging signs(ground-glass opacity)of pneumonia developed in 68(73.9%)cases.The fever was positively correlated with multiple foci,ground-glass opacity with consolidation,maximal patch shadow length,and air bronchogram of CT imaging(r=0.312,0.269,0.364,0.385,respectively;P<0.05),whereas cough was negatively correlated with subpleural striae(r=-0.293,P<0.05).Conclusion There exists characteristic CT imaging of ordinary COVID-19.CT examination is pivotal for diagnosis of asymptomatic or mild COVID-19.
