Abstract
The aims of this study were to determine the performance of different imaging modalities in the diagnosis of corona virus disease 2019 (COVID-19) and to familiarize radiologists with a possible chest X-ray, chest computed tomography (CT), ultrasonography (US) and magnetic resonance imaging (MRI) patterns of the disease onset and complications, which visualize in the image and to reduce the misdiagnosis rate of radiologists for COVID-19. This study was the review of the literature, which included 50 studies 35 original articles, 11 case reports and 4 literature reviews with a diagnosis of COVID-19 infection from different countries and gender. The researchers reviewed radiological signs and compared them in different imaging modalities. This study revealed that published studies of COVID-19 mostly from China; CT is most imaging modality used for evaluation and diagnosis of COVID19, chest CT (64.71%), chest X-ray (19.2%), US (13.23%), MRI (2.94%) and chest CT had a low rate of missed diagnosis of COVID-19 (3.9%, 2/51). The most frequent findings are ground-glass opacities (GGO) 80% and patchy lung consolidation 28%. The distribution is most often bilateral, peripheral and lower zone predominant. This study concluded that radiological findings might be useful as a standard method for the rapid diagnosis of COVID-19 to optimize the management of patients. However, additional high-quality studies are needed to convince policy makers. In addition, current study present guidelines to help focus future research in this area. Furthermore, this study found that chest CT was a reliable diagnostic tool for COVID-19.
