Can dual-energy CT improve the assessment of tumor margins in oral cancer?

Summary Objectives The aim was to investigate the image quality of dual-energy computed-tomography (DECT) compared to single-energy images at 80 kV and 140 kV in oral tumors. Materials and methods Forty patients underwent a contrast-enhanced DECT scan on a definition flash-CT. Four reconstructions (...
