Abstract

Background: Coronaviruses are a large family of RNA viruses, which range from the common cold virus to the causative agent of more severe diseases. Coronavirus was declared a pandemic in December 2019 in Wuhan, China. Iran has been an endemic zone for the spread of the coronavirus since the outset of this global epidemic and has remained among the countries largely affected by high rates of the disease. Objectives: The present study aimed to investigate the range of the chest computed tomography (CT) scan findings among the hospitalized patients with COVID-19 in Kermanshah, Iran during March-April 2020 to contribute to the accurate diagnosis of the infected patients. Methods: The sample population consisted of 286 hospitalized patients diagnosed with or suspected of the coronavirus disease. Chest CT-scan images and clinical data were reviewed, and their correlation was analyzed. Results: In total, 176 patients (61.53%) were male, and 110 (38.47%) were female. The mean age of the patients was 56 years. Polymerase chain reaction (PCR) results showed that 35.31% of the cases had coronavirus, while the results were negative in 64.69% of the cases. In addition, the CT-scan findings indicated 77.27% abnormal and 22.73% normal chest CT-scans. Among the patients, 75.87% recovered completely, and 18.53% died. The major CT abnormalities were diffuse ground-glass opacification (35.66%), peripheral ground-glass opacification (bilateral; 21.33%), and a combination of diffuse and peripheral ground-glass lesions (18.88%). The consolidation lesion of one lobe was detected in 16 patients, and the consolidation lesion of more than one lobe was observed in 40 patients. Conclusions: According to the results, the most common chest CT-scan findings in COVID-19 include diffuse ground-glass opacification, peripheral ground-glass opacification (bilateral), central ground-glass opacification (bilateral), a combination of diffuse and peripheral ground-glass opacification, a combination of central and peripheral ground-glass opacification, the consolidation lesion of one lobe, and the consolidation lesion of more than one lobe. Furthermore, significant correlations were observed between the CT-scans and the main clinical symptoms, while no significant correlations were denoted between the chest CT-scan and PCR results.
冠状病毒病住院患者胸部ct扫描谱分析
背景:冠状病毒是一大类RNA病毒,其范围从普通感冒病毒到更严重疾病的病原体。2019年12月,冠状病毒在中国武汉被宣布为大流行。自这场全球流行病开始以来,伊朗一直是冠状病毒传播的流行区,并且仍然是受该疾病高发病率影响最大的国家之一。目的:本研究旨在了解2020年3 - 4月伊朗克尔曼沙阿住院的COVID-19患者的胸部计算机断层扫描(CT)扫描范围,以帮助准确诊断感染患者。方法:对286例确诊或疑似冠状病毒病住院患者进行调查。回顾胸部ct扫描图像与临床资料,并分析其相关性。结果:男性176例(61.53%),女性110例(38.47%)。患者的平均年龄为56岁。聚合酶链反应(PCR)结果显示,35.31%的病例感染了冠状病毒,64.69%的病例结果为阴性。胸部ct异常占77.27%,正常占22.73%。痊愈率为75.87%,死亡率为18.53%。主要CT异常为弥漫性磨玻璃混浊(35.66%)、周围性磨玻璃混浊(双侧;21.33%),弥漫性和周围性磨玻璃病变合并(18.88%)。单叶实变16例,多叶实变40例。结论:根据结果,COVID-19最常见的胸部ct表现为弥漫性磨玻璃混浊、周围磨玻璃混浊(双侧)、中央磨玻璃混浊(双侧)、弥漫性和周围磨玻璃混浊合并、中央和周围磨玻璃混浊合并、单叶实变、多叶实变。此外,ct扫描与主要临床症状之间存在显著相关性,而胸部ct扫描与PCR结果之间无显著相关性。
