Abstract

The new coronavirus disease, which started in Wuhan, quickly transformed into a pandemic and a life-threatening global infection. Understanding Covid-19-specific views can facilitate defining more accurate CT scan diagnostic criteria for this disease. These views include ground-glass opacity (GGO), consolidation, interlobular septal thickening, reticular, and crazy paving. This case series aimed to assess six Covid-19 patients displaying the target sign view in lung CT scans.
