COVID-19 IMAGING
COVID-19 is a viral disease also known as SARS-CoV-2 or severe acute respiratory syndrome coronavirus 2. The diagnosis is made by a positive PCR test, which is highly specific. CT(Computed Tomography) has a higher sensitivity but lower specificity and can play a role in the diagnosis and treatment of the disease. 👉Clinical Features COVID-19 usually presents with fever (85%), cough (70%) and shortness of breath (43%), but abdominal and other symptoms are possible and the disease can be asymptomatic. Overall mortality rate is 2.3% in some series of patients who had a positive test for COVID-19. Since we do not know the number of people who were infected but not tested for the virus, the actual mortality rate of all the people that are infected is probably much lower. Illness severity can vary from mild to critical. Mild: no symptoms, mild coughing and fever. Severe: dyspnea, hypoxia or > 50% lung involvement on imaging. Critical: respiratory failure, shock, multi-organ failure.
