Detection rates of parenchymal areal opacities in the initial analysis with the MRI sequences incoherent GRE (gradient echo), volume interpolated GRE, and UTE (ultrashort echo time) based on the types of the opacities

Detection rates	Incoherent GRE	Volume interpolated GRE	UTE
Overall parenchymal areal opacities
	77.8% (35 of 45)*	80.0% (36 of 45)*	93.3% (42 of 45)*
Consolidations
	100.0% (16 of 16)	100.0% (16 of 16)	100.0% (16 of 16)
Ground-glass opacities
	50.0% (5 of 10)	60.0% (6 of 10)	90.0% (9 of 10)
Parenchymal bands
	73.7% (14 of 19)	73.7% (14 of 19)	89.5% (17 of 19)

McNemar tests evaluated differences between each of the GRE sequences in comparison to UTE images
