This page contains medical information for clinicians on the 2019 Novel Coronavirus (COVID-19, also called 2019-nCoV and now clinically SARS‐CoV‐2). This section includes articles on medical imaging of the virus for radiologists, new technologies being deployed to fight the virus and clinical information from various sources. Here are direct links for medical professionals to COVID-19 resources from the U.S. Food and Drug Administration (FDA), Centers for Disease Control (CDC) and the World Health Organization (WHO). Daily world-wide statistics on the coronavirus outbreak are available from the WHO Situations Reports. Centers for Medicare and Medicaid Services (CMS) frequently asked questions and answers (FAQs) for healthcare providers regarding Medicare payment for laboratory tests and other services related to the COVID-19
16-year-old girl with coronavirus disease (COVID-19) and known history of tuberous sclerosis who presented with acute hypoxic respiratory distress. Reverse transcription–polymerase chain reaction testing confirmed diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
A, Frontal chest radiograph obtained at initial presentation shows bilateral lower lung zone–predominant consolidations and, to lesser extent, ground-glass opacities. B, Frontal chest radiograph obtained 2 days after hospital admission shows interval increase in consolidation in bilateral lower lung zones. C, Frontal chest radiograph obtained 6 days after hospital admission and treatment shows interval improvement in consolidations in bilateral lower lung zones.
Figure 2: Pulmonary CT angiography of a 68 year old male. The CT scan was obtained 10 days after the onset of COVID-19 symptoms and on the day the patient was transferred to the intensive care unit. Axial CT images (lung windows) (a,b) show peripheral ground-glass opacities (arrow) associated with areas of consolidation in dependent portions of the lung (arrowheads). Interlobular reticulations, bronchiectasis (black arrow) and lung architectural distortion are present. Involvement of the lung volume was estimated to be between 25% and 50%. Coronal CT reformations (mediastinum windows) (c,d) show bilateral lobar and segmental pulmonary embolism (black arrows). Courtesy of RSNA
According to the 10 authors from multiple institutions across the US who reviewed the most frequently cited studies on the subject: 'Test performance and management issues arise when inappropriate and potentially overreaching conclusions regarding the diagnostic performance of CT for COVID-19 pneumonia are based on low-quality studies with biased cohorts, confounding variables, and faulty design characteristics.
