Table 1. Dual-Energy CT Applications Summary.

Location/Region	Material Seperation/Virtual Monoenergetic Beam	Iodone Quantification
Brain	Helps to differentiate between tumor and bleed	Helps to differentiate between bleed and contrast
Cardiac	Low virtual monoenergetic KeV improves visualization of myocardial fibrosis
Lungs		High iodine density/increased perfusion of the lung parenchyma around the pulmonary opacity in COVID-19
		Decrease perfusion of the lung parenchyma in the region of pulmonary infarct suggesting hypoperfused lung/pulmonary embolism
Abdomen	Differentiate mural hypoperfused segment from normal perfused bowel wall	Iodine map images can increase the visibility of the iodine content in bowel wall and thus increasing the diagnostic confidence of visualizing intramural hemorrhage
	Differentiate tumors
	Helpful in identifying the composition of various kidney/gall stones
Vascular imaging	Blooming artifacts from calcified plaques can be reduced
Bones	VNC images can be created to differentiate chronic fractures from acute and non-displaced CT occult fractures
Metallic artifacts	High monoenergetic beam can reduce metallic artifacts

keV = kiloelectron volt, VNC = virtual non-contrast
