Podcast 560: Imaging in a COVID world

Contributor: Don Stader, MD

Educational Pearls:

  • COVID-19 commonly appears as a bilateral patchy infiltrate on chest radiograph, but this is a non-specific finding
    • Sensitivities range from 17-70% for COVID-19
    • Many other viral pneumonias such as RSV and influenza can have similar findings
  • Point-of-care ultrasound (POCUS) demonstrates B-lines, water-fall sign, or hepatization of the lung, but these are also non-specific
  • Computerized tomography (CT) appears to be one of the more sensitive tests for detecting COVID-19, demonstrating ground-glass opacities - often before or without the patient having symptoms
    • However, routine use of CT for diagnosis COVID-19 is strongly discouraged by many medical societies and the CDC
  • Imaging may not be necessary in most patients presenting with suspected COVID-19 for multiple reasons:
    • Diagnosis is often clinical suspicion, with or without confirmatory PCR testing (if available)
    • Imaging does little to change the management in the majority of patients with COVID-19
    • Obtaining imaging exposes additional healthcare workers
    • Cleaning protocols for units (especially CT) can be extensive and require significant downtime of the machine, thereby leading to delays in care
