低kVp设置可在CT上提供较高的造影剂显著性，但可能导致较高的图像噪声，尤其是在体型较大的患者中。与常规CT相比，双能量CT的材料分解可以通过成分区分肾结石，量化组织铁储备，改善病理性高增强的检测，并减少造影剂和辐射剂量。随着这些令人兴奋的技术的普及，还需要进一步的临床研究和技术改进。
Low kVp settings provide high conspicuity of contrast materials at CT but may result in high image noise, particularly in larger patients. Material decomposition at dual energy CT can differentiate renal stones by their composition, quantify tissue iron stores, improve the detection of pathologic hyperenhancement, and reduce contrast material and radiation dose compared to conventional CT. Further clinical research and technique refinement will be needed as the usage of these exiciting technologies spreads.
