Résumé

Dual-energy computed tomography (DECT) can provide iodine, electron density (ED), and effective atomic number Z (Z We acquired DECT and perfusion CT (PCT) images in 24 patients with histologically diagnosed meningioma. Regions of interest (ROIs) were placed at the tumor in iodine, ED, and Z Contrast rZ DECT predicted vascular density with lower radiation exposure compared to PCT. DECT could potentially replace PCT for evaluating the vascularity of meningiomas.
