Risk of in-hospital death associated with Covid-19 lung consolidations on chest computed tomography – A novel translational approach using a radiation oncology contour software
Lung consolidations in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are commonly visualized on radiological exams as ground-glass and diffuse patchy opacities [1–3]. Due to superior spatial resolution, these changes are usually better visualized by chest computed tomography (CT) instead of simple radiography [4,5].Abdominal gastrointestinal imaging findings on computed tomography in patients with COVID-19 and correlation with clinical outcomes
Pulmonary imaging finding of Coronavirus disease 2019 (COVID-19) has been widely described, but until now few studies have been published about abdominal radiological presentation. The aim of this study was to provide an overview of abdominal imaging findings in patients with COVID-19 in a multicenter study and correlate them with worse clinical outcomes.Cardiac magnetic resonance imaging during the COVID-19 pandemic: A southern Italian single-center experience
COVID-19 pandemic emergency has put a strain on worldwide healthcare systems requesting a sudden adjustment of the medical routine to extraordinary needs [1–4]. The onset and progression of pandemic significantly differed between countries, with the most imposing strict social limitations. The severe acute respiratory syndrome coronavirus-2 is responsible for COVID-19, being transmitted by droplets from person to person [5,6]. In order to reduce the risk of patient-to-patient, patient-to-health-workers and vice-versa contagion and to optimize hospital resources, all patients scheduled for diagnostic imaging procedures with non-severe symptoms or not candidate to invasive or surgical treatments have been postponed [7,8].Ventilator associated lung injury in severe COVID-19 pneumonia patients – Case Reports: Ventilator associated lung injury in COVID-19
Management of severe coronavirus disease 2019 requires advanced respiratory support modalities including invasive mechanical ventilation (IMV), continuous positive airway pressure (C-PAP), and non-invasive ventilation ((NIV). IMV leads to either subtle forms of lung injury (pulmonary edema, lung cysts) or more severe form of lung injury manifested as subcutaneous emphysema, pneumomediastinum, and pneumothorax (herein collectively termed barotrauma). We have described two cases showing the two end of spectrum of ventilator associated lung injury (VALI).The time course of chest CT lung changes in COVID-19 patients from onset to discharge
Coronavirus disease 2019 (COVID-19), a novel disease caused by the strain of coronavirus recognized as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has quickly spread globally [1]. As of 31 July 2020, 18 million individuals diagnosed with COVID-19, and more than 540,000 have died from this disease. The number of deaths due to COVID-19 is expected to increase [2]. The SARS-CoV-2 virus has been known to enter the respiratory tract, damage the lungs and cause pneumonia, resulting in the acute respiratory distress syndrome (ARDS) and severe hypoxemia [3,4]COVID-19 pneumonia manifestations at the admission on chest ultrasound, radiographs, and CT: single-center study and comprehensive radiologic literature review

Coronavirus Disease-2019 (COVID-19) originated in the Wuhan, Hubei Province, China in November 2019 and has since been declared a pandemic by the WHO. COVID-19 is an acute infectious disease, primarily affecting the respiratory system. Currently, real-time reverse transcription polymerase chain reaction (RT-PCR) performed on respiratory specimens is considered the reference by which to diagnose COVID-19. However, the limitations of RT-PCR, specifically, the fact that it is time-consuming and inadequate for the assessment of disease severity, have affected the process of epidemiological disease containment and has taken a toll on the healthcare management chain.Review of chest CT manifestations of COVID-19 infection
COVID-19 is caused by an RNA virus, SARS CoV-2 (severe acute respiratory syndrome coronavirus 2) which is part of the Coronaviridae family (which includes SARS-CoV and MERS(Middle East respiratory syndrome)-CoV) [1,2]. The virus infects the upper respiratory tract, can cause pneumonia, and is easily transmitted from human to human. The initial epicenter was in Wuhan, the capital city of China’s Hubei province, back in December 2019. The disease has rapidly spread to the rest of the world, particularly in Europe and the US, which are now harboring the largest number of cases in the world.Tailored breast imaging during the first wave and preparedness for the second wave of COVID-19 pandemic
The coronavirus outbreak that emerged in Wuhan, China, in late December was caused by a novel Coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), and within a time frame of just a few months, it evolved into a pandemic. As of May 29, 2020, the coronavirus disease 2019 (COVID-19) pandemic has resulted in 5,701,337 confirmed cases and 357,688 deaths worldwide, including 87,902 cases and 6799 deaths in Canada [1]Discrimination of pulmonary ground-glass opacity changes in COVID‐19 and non-COVID-19 patients using CT radiomics analysis
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) now officially termed coronavirus disease 2019 (COVID-19) has rapidly spread globally, and on 11th March 2020 was declared a global pandemic by the World Health Organization [1]. As of Aug 15 2020, there have been over 21,000,000 confirmed cases reported in 216 countries [2]. For the diagnosis of COVID-19, next-generation sequencing or real-time reverse transcription polymerase chain reaction methods are used as reference standards [3] but computed tomography (CT) has also been reported to be effective in assisting the early detection of COVID-19 cases [4].Deep learning for automatic quantification of lung abnormalities in COVID-19 patients: First experience and correlation with clinical parameters
In 2020 a novel, highly infectious coronavirus, SARS-CoV-2, rapidly developed to a worldwide pandemic. The clinical appearance of the infection ranges from mild symptoms to fulminant acute respiratory distress syndrome [1–3]. Due to the rapidly growing flood of patients in need for medical care, health care systems were quickly on the verge of collapse. Recent experience showed that it was difficult to respond efficiently to this extreme demand even in developed Western countries [4].Evaluation of chest CT and clinical features of COVID-19 patient in Macao
Coronavirus disease-19 (COVID-19) was firstly reported in December 2019 in Wuhan, China and soon after, the number of cases increased rapidly worldwide. As of May 2, 2020, more than 3,000,000 confirmed cases have been reported world. In Macao, there were 45 confirmed COVID-19 cases until May 2, 2020.Imaging differences between coronavirus disease 2019, severe acute respiratory syndrome, and Middle East respiratory syndrome
