Nair JR, et al. - In view of the observation that dual-energy computed tomography high energy virtual monochromatic images (VMIs) can reduce artifact but suppress iodine attenuation in enhancing tumor, researchers aim to identify VMI(s) that strike the best balance between iodine detection and artifact reduction. They observe that high energy VMIs less than 100 keV can achieve modest artifact reduction while preserving sufficient iodine attenuation and may represent a useful additional reconstruction for evaluation of head and neck cancer.
