Audience: Radiology Residents, Radiologists, and other Medical Professionals
Recommended playback speed: 1.25 to 1.5
Learning Objectives, -Identify and describe the spectrum of findings in viral pneumonia
-Explain a basic algorithm for managing patients with suspected viral pneumonia in a radiology department
Note: CT is not recommended for screening or diagnosis of COVID-19 pneumonia by The American College of Radiology or the Society of Thoracic Radiology. CT should only be used when indicated by the severity of the patients symptoms.
Summary, The Findings are non-specific with CT showing a pattern of acute lung injury (organizing pneumonia)
There is a broad differential diagnosis, -Viral pneumonia (Influenza A, influenza B, RSV, coronavirus, rhinovirus, parainfluenza, and adenovirus)
-Bacteria pneumonia (Legionella, mycoplasma)
-Drug induced (chemotherapy, immunotherapy)
-Cryptogenic organizing pneumonia.
New consensus statement, directly quoted, " Essentials
■ Imaging is not indicated in patients with suspected COVID-19 and mild clinical features unless they are at risk for disease progression.
■ Imaging is indicated in a patient with COVID-19 and worsening respiratory status.
■ In a resource-constrained environment, imaging is indicated for medical triage of patients with suspected COVID-19 who present with moderate-severe clinical features and a high pre-test probability of disease"
Clinical context is key with specificity dependent on a high pretest probability, Symptoms of COVID-19: Fever, shortness of breath, cough, fatigue, no rhinorrhea (runny nose)
Please Wash Your Hands (for 20 seconds and more frequently than in the past)
Do Not Touch Your Face (Touching a contaminated surface and then you face is a primary route of spread).
If you are over 60 y/o (or under 60 with high blood pressure, diabetes, or cardiovascular disease), consider staying at home, and avoiding groups, crowds, and travel.
