Coronaviruses are a diverse group of viruses that infect both animals and humans.Even though the existence of coronavirus and its infection to humans is not new,the 2019-novel coronavirus(nCoV)caused a major burden to individuals and society i.e.,anxiety,fear of infection,extreme competition for hospitalization,and more importantly financial liability.The nCoV infection/disease diagnosis was based on non-specific signs and symptoms,biochemical parameters,detection of the virus using reverse-transcription polymerase chain reaction(RTPCR),and X-ray-based imaging.This review focuses on the consolidation of potentials of X-ray-based imaging modality[chest-X radiography(CXR)and chest computed tomography(CT)]and low-dose radiation therapy(LDRT)for screening,severity,and management of COVID-19 disease.Reported studies suggest that CXR contributed significantly toward initial rapid screening/diagnosis and CT-imaging to monitor the disease severity.The chest CT has high sensitivity up to 98%and low specificity for diagnosis and severity of COVID-19 disease compared to RT-PCR.Similarly,LDRT compliments drug therapy in the early recovery/Less hospital stays by maintaining the physiological parameters better than the drug therapy alone.All the results undoubtedly demonstrated the evidence that X-ray-based technology continues to evolve and play a significant role in human health care even during the pandemic.
