新型冠状病毒（2019-nCoV）肺炎临床与CT影像学征象探讨

目的 分析新型冠状病毒（2019-nCoV）肺炎的临床表现与CT影像学征象，提高对该病的认识。材料与方法 回顾分析解放军总医院第五医学中心确诊的63例NCP患者的临床资料和胸部CT影像学表现，根据NCP诊疗方案（试行第六版），将所有患者分为轻型（13）普通型（31例）、重型（11例）和危重型（8例），分析CT影像学表现。运用SPSS 21.0软件进行统计学分析。结果 NCP患者常见临床表现为发热有49例（77.8%），咳嗽36例（57.1%），乏力10例（15.8%）。实验室检查白细胞计数正常或减低54例（85.7%），淋巴细胞计数减低18例（28.6%），C反应蛋白升高33例（52.3%）。CT表现为双肺分布48例（96%），双下肺最多见47例（94.0%），主要表现为磨玻璃影、实变影及纤维化等，其他常见征象包括铺路石征、胸膜平行征、空气支气管征、血管增粗征、晕征及反晕征等，有3例胸腔积液均为危重型患者。结论 NCP患者临床及胸部CT影像学表现具有一定特征性，不仅能早期诊断，还能对临床病程及严重程度进行评估。

Clinical and CT imaging features of novel coronavirus (2019-nCoV) pneumonia

Objective To analyze the clinical manifestations and CT imaging findings of novel coronavirus (2019-nCoV) pneumonia in order to improve the understanding of the disease. Methods The clinical data and chest CT imaging findings of 63 patients with NCP diagnosed by the Fifth Medical Center of PLA General Hospital were analyzed retrospectively. according to the diagnosis and treatment scheme of NCP (trial sixth edition), all patients were divided into mild (13) ordinary type (n=31), severe type (n=11) and critical type (n=8). The imaging findings of CT were analyzed. SPSS 21.0 software was used for statistical analysis. Results The common clinical manifestations of NCP patients were fever in 49 cases (77.8%), cough in 36 cases (57.1%), and fatigue in 10 cases (15.8%). Laboratory tests showed that white blood cell count was normal or decreased in 54 cases (85.7%) and lymphocyte count decreased in 18 cases (28.6%), C reactive protein increased in 33 cases (52.3%). CT showed bilateral lung distribution in 48 cases (96%) and double lower lungs in 47 cases (94.0%). The main manifestations were ground glass shadow, consolidation and fibrosis. other common signs included paving stone sign, pleural parallel sign, air bronchus sign, vascular thickening sign, halo sign and halo sign. 3 cases of pleural effusion were critical patients. Conclusion The clinical and chest CT findings of patients with NCP have certain characteristics, which can not only make early diagnosis, but also evaluate the clinical course and severity of the disease.
