Objective To summarize the recent application progress of dual-energy CT in pancreatic imaging. Methods The domestic and international published literatures related to the application of dual-energy CT in pancreatic imaging in recent years were collected and reviewed. Results Dual-energy CT could provide the morphological image and function information of tissues and organs simultaneously. At present, the clinical application of dual-energy CT in pancreatic imaging included low tube voltage technology, iodine overlay, virtual non-enhanced imaging, and monoenergetic imaging. Conclusion Dual-energy CT could contribute to detecting pancreatic lesions, reducing radiation dose, and improving image quality in pancreatic imaging.
