CT manifestations of COVID-19
CT findings	Definition	CT picture
Ground glass opacity	Hazy opacity in the lungs with well defined bronchial and vascular margins the most common imaging finding due to infection, chronic interstitial lung disease, and acute lung injury
Consolidation	a parenchymal density with ill-defined bronchial and vascular margins filling with infectious material [fluid, cells, tissue] due to cellular exudates in alveoli	[[file
Crazy paving pattern	Septal thickening of inter and intra-lobar regions with the background of the Ground glass opacity Similar to paving stones Due to alveolar edema and acute inflammation of the lung Sign of progression
Reticuldar pattern	Linear opacities in the lungs Due to Interstitial thickening of inter and intralobular septa	[[file
Air bronchogram	Air-filled bronchi Low attenuated areas in the lung	[[file
Bronchiectasis	irreversible dilatation of the lung airways Bronchus diameter more than 1.5 cm due to inflammation, obstruction and impaired clearance	[[file
