The role of dual-energy computed tomography in the diagnosis of gout and other crystalline arthropathies: A review

Abstract

The importance of dual-energy computed tomography in the diagnosis of gout, the principles of dual-energy computed tomography, the accuracy of the methodology, and the types of artifacts are discussed in this study. The possible dependence of the presence of deposits of sodium monourate on other clinical data and the role of dual-energy computed tomography in the differential diagnosis of other crystalline arthropathies are considered. The dual-energy computed tomography has several advantages, including noninvasiveness, speed of execution, and a significant reduction in the risk of iatrogenic consequences compared with diagnostic arthrocentesis, which is the gold standard in diagnosing gout. Dual-energy computed tomography can accomplish gout detection, treatment, and differential diagnosis.
