Abstract:
Cholelithiasis is one of the most common diseases of the digestive system,and the accurate preoperative diagnosis of cholelithiasis is important to guiding treatment and improving prognosis.Dual-energy CT based on material decomposition and post-processing techniques can generate virtual monoenergetic images,virtual noncontrast images,calcium-and fat-based material decomposition images and Rho/Z images which are helpful for detecting isoattenuating gallstones,and offer objective evidence for diagnosing gallstone disease and its complications.This article reviews the principle of dual-energy CT and its progress in cholelithiasis.
