Network Models and Optimizationractice; it is based on different absorption of X-rays at different kV, leading to better material characterization, in particular iodine. Ione maps and virtual non-contrast images can be digitally generated. Multi-energy CT (or spectral CT) is not clinically applied yet. It is based on new detector

Mitsuo Gen,Runwei Cheng,Lin Lingraphy (DECT) implies the application of two different energies, adding to the classic single-energy multi-detector CT study, information yielded from material differentiation derived from the interaction between tissues and different energy levels. Multi-energy CT (spectral imaging) is a more speci
