title: Dual-energy computed tomographic scanners: principles, comparisons, and contrasts.
abstract: The underlying principles of dual-energy computed tomography are reviewed, with comparison and contrast of the primary dual-energy computed tomographic scanners that are currently in use. Practical clinical implications of the differences in hardware, software, and imaging processing implementations are discussed, noting the rationale for convergence of technology and terminology.
