Abstract

During the past decade, a major technological challenge began with the introduction of dual energy computed tomography imaging in the clinical setting. Spectral imaging and the generation of low energy monochromatic imaging and material-specific datasets may contribute in a significant reduction in iodinated contrast volume during vascular computed tomography angiographies without hampering image quality or interpretability.
