Dual-Energy Computed Tomography Angiography of the Head and Neck and Related Applications.
Dual-energy computed tomography (DECT) has become an increasingly widespread and useful component of the neuroimaging armamentarium, offering automated bone removal, metallic artifact reduction, and improved characterization of iodinated contrast enhancement. The application of these techniques to CT neuroangiography enables a number of benefits including more efficient 3D post-processing, contrast dose reduction opportunities, successful differentiation of hemorrhage from contrast staining following thromboembolic recanalization therapy, improved detection of active contrast extravasation in the setting of intracranial hemorrhage, and more precise characterization of atheromatous steno-occlusive disease.
