The main challenge is surely represented by the execution of CT and MR scans, which usually require the transfer of patients, calling to action numerous healthcare professionals. As for previous epidemics like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), some hospitals adopted portable CT scanners in emergency rooms (ER) or intensive care units (ICU) [22, 23] , whereas others used mobile devices on trucks [21] . In addition, because of such difficulties, ultrasound (US) was broadly used in the ER, COVID-19 wards, and ICU. Indeed, as demonstrated in several studies, clinicians and anesthesiologists successfully diagnosed and monitored COVID-19 patients, with the US reducing intra-hospital patient transfers [24] [25] [26] . The above-summarized evidence demonstrates that, since the declaration of the pandemic by the World Health Organization (WHO, Geneva, Switzerland) on 11 March 2020 [27] , the experience shared by the scientific community worldwide gave us the chance to learn the typical features of COVID-19 in the acute and subacute phases. Nevertheless, much is still to be understood, especially about the long-term consequences of the disease, such as the occurrence of pulmonary fibrotic changes. Thus, I strongly believe that more needs to be done to face this challenge and support our clinicians in dealing with this complex disease. This Special Issue is a chance for radiologists and clinicians to increase our knowledge about COVID-19, considering also its long-term effects. Review articles about the current evidence, as well as original articles presenting novel findings, will help us in improving our clinical practice. Research addressing also technical and organizational aspects that characterize the role of diagnostic imaging in the current pandemic will represent a source of growth for healthcare professionals. As Guest Editor, I would like to sincerely thank all authors for their precious contributions and all readers for their interest in this Special Issue and for sharing the acquired knowledge.
