The "gold standard" for the diagnosis and evaluation of urinary stones is native computed tomography, which allows determining stone localization and size of with high accuracy. However, this imaging technique has limited diagnostic usefulness in determining the stone chemical composition. The newly introduced method of dual-energy computed tomography, based on obtaining images at two different energy levels is highly effective in determining the composition of urinary stones. The review outlines the principles and methods of performing dual-energy computed tomography using various scanners. The authors analyze the results of using this method for diagnosing urolithiasis, determining the stone chemical composition and point out the limitations and difficulties encountered in its application.
泌尿系统结石诊断和评估的“金标准”是平扫计算机断层扫描，它能够高精度地确定结石的位置和大小。然而，这种成像技术在确定结石化学成分方面的诊断价值有限。新引入的基于在两个不同能量水平获取图像的双能计算机断层扫描方法，在确定泌尿系统结石成分方面非常有效。这篇综述概述了使用各种扫描仪进行双能计算机断层扫描的原理和方法。作者分析了使用该方法诊断尿路结石、确定结石化学成分的结果，并指出了其应用中遇到的局限性和困难。
