Dual-Energy CT Applications in Head and Neck Imaging

OBJECTIVE. Dual-energy scanning is a breakthrough in CT technology that has several applications in chest and abdominal imaging. Dual-energy CT also has potential for head and neck imaging. This review describes the role of dual-energy CT in head and neck imaging. CONCLUSION. As with other body regions, both image fusion and material characterization dual-energy applications can be used for head and neck imaging. Early results are promising, and further research is encouraged.
