Abstract :Aim: In September 2020, a variant of the SARS-CoV-2 virus was detected in England and it became the dominant type in most of the countries. The clinical behavior of the B.1.1.7 variant COVID-19 infectionis different from the Wuhan type.So we aimed to investigate whether there are any differences in computed tomography insert ignore into journalissuearticles values(CT); imaging findings of pneumonia caused by COVID-19 variants. Material and Method: 340 patients who admitted to the emergency departmentwith symptoms of dyspnea and chest pain suspecting COVID-19 pneumonia and pulmonary embolism were included in the study. Oncology insert ignore into journalissuearticles values(n:12); and pediatric insert ignore into journalissuearticles values(n:8); patients, patients with negative PCR test insert ignore into journalissuearticles values(n:56);, and patients infected with different variant insert ignore into journalissuearticles values(n:6); were excluded leaving 258 patients grouped into two insert ignore into journalissuearticles values(B.1.1.7 and Wuhan type); for evaluation of CT findings such as pleural thickening,pleural and pericardial effusion, consolidation, GGO presence and distribution, upper lobe involvement, pulmonary embolism, tree in bud pattern, centrilobuler nodule, revers halo sign, and hepatosteatosis. Results: A statistically significant difference was obtained between the two groups in terms of pleural thickening insert ignore into journalissuearticles values(p=0.020);, upper lobe involvement insert ignore into journalissuearticles values(p=0.037);, localization of GGO insert ignore into journalissuearticles values(p=0.001);, presence of pleural effusion insert ignore into journalissuearticles values(p=0.025);, embolism insert ignore into journalissuearticles values(p=0.011); and presence of consolidation insert ignore into journalissuearticles values(p=0.042);. However, no significant difference was found for the development of hepatosteatosis insert ignore into journalissuearticles values(p=0.520);. Conclusion: There aredifferences in radiological findings between B.1.1.7 variant and Wuhan type. In our study atypical radiological findings are more common in B.1.1.7 type. In addition, radiological findings that seen in severe COVID-19 pneumonia are more common in B.1.1.7.
