Covid-19: free resources to support radiographers

The first report of a new Coronavirus disease (Covid-19) was in December 2019 and the disease was declared a pandemic by the World Health Organisation (WHO) in March 2020.1 At this point WHO called on governments to change the course of the outbreak by taking urgent and aggressive action. By the end of April, the number of cases was in excess of 3 million with 211,350 deaths worldwide. Covid-19 is related to previous pandemics - SARS-CoV-1 (SARS) and Middle East respiratory syndrome (MERS)2 and it can be asymptomatic or result in mild to severe symptoms. Unlike influenza it can be contagious before symptoms are apparent.3 Due to the highly contagious nature of the disease, rapid and reliable diagnosis is critical. Medical imaging has valuable roles in the diagnosis and management of the Covid-19 patient and radiographers have already started to share their experiences with imaging it.4, 5, 6, 8 Chest computed tomography (CT) has diagnostic value,9 though presents challenges including CT availability, the complexity of imaging patients who may be on ventilators and the time taken to decontaminate the CT scanner and room after a Covid-19 patient has used it. For these reasons mobile chest radiography (CXR) has become the most commonly utilised imaging modality for the radiological follow up of lung abnormalities. For the purpose of raising the profile of web-based resources to help radiographers understand more about Covid-19, this Guest Editorial outlines why and how the resources were created as well as explaining what they are and how to access them.
