Utility of various dual-energy CT data sets for imaging of the salivary glands

VNC	Identification of sialolithiasis
	Identification of phleboliths in haemangioma
High-kV and high-keV (VMC) images	Evaluation of lesions in the presence of streak artefacts arising from dental implants
Low-kV and low-keV (VMC) images	Visualization of less conspicuous lesion
	Delineation of tumour margins
Iodine overlay images	Objective differentiation of the enhancing solid tumour vs solid-cystic lesion vs simple cyst
	Assessment of infection, inflammation and abscess
Bone removal images	Evaluation of skull base extension of malignant lesions

kV, kilovoltage; keV, kiloelectron volt; VMC, virtual monochromatic; VNC, virtual non-contrast.
