Evaluation of optimal monoenergetic images acquired by dual-energy CT in the diagnosis of T staging of thoracic esophageal cancer

Abstract

Key points Precise preoperative T staging in esophageal cancer patients is critical. Dual-energy CT is widely used to improve the SNR and CNR of images. The multiple quantitative parameters from DECT exhibited potential in distinguishing T staging.
