This pandemic represents a serious public health risk. Therefore, early and accurate diagnosis is essential to control disease progression. Radiological examination plays a crucial role in the early identification and management of infected patients.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The aim of this review was to identify the diagnostic value of different imaging modalities used for diagnosis of COVID-19.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A comprehensive literature search was conducted using the PubMed, Scopus, Web of Science, and Google Scholar databases. The keywords diagnostic imaging, radiology, respiratory infection, pneumonia, coronavirus infection and COVID-19 were used to identify radiology articles focusing on the diagnosis of COVID-19 and to determine the diagnostic value of various imaging modalities, including x-ray, computed tomography (CT), ultrasound, and nuclear medicine for identification and management of infected patients.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n We identified 50 articles in the literature search. Studies that investigated the diagnostic roles and imaging features of patients with COVID-19, using either chest CT, lung ultrasound, chest x-ray, or positron emission topography\/computed tomography (PET\/CT) scan, were discussed. Of these imaging modalities, chest x-ray and CT scan are the most commonly used for diagnosis and management of COVID-19 patients, with chest CT scan being more accurate and sensitive in identifying COVID-19 at early stages. Only a few studies have investigated the roles of ultrasound and PET\/CT scan in diagnosing COVID-19.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Chest CT scan remains the most sensitive imaging modality in initial diagnosis and management of suspected and confirmed patients with COVID-19. Other diagnostic imaging modalities could add value in evaluating disease progression and monitoring critically ill patients with COVID-19.<\/jats:p>\n
