Dual-energy CT is being increasingly used for abdominal imaging due to its incremental benefit of material characterization without significant increase in radiation dose. Knowledge of the different dual-energy CT acquisition techniques and image processing algorithms is essential to optimize imaging protocols and understand potential limitations while using dual-energy CT renal imaging such as urinary calculi characterization, assessment of renal masses and in CT urography. This review article provides an overview of the current dual-energy CT techniques and use of dual-energy CT in renal imaging.
由于双能 CT 在物质特征化方面具有增量优势，而辐射剂量增加不明显，因此其在腹部成像中的应用越来越广泛。了解不同的双能 CT 采集技术和图像处理算法对于优化成像方案以及理解在使用双能 CT 肾成像时的潜在局限性（如尿路结石特征、肾肿块评估和 CT 尿路造影）至关重要。本文综述了目前的双能 CT 技术及其在肾成像中的应用。
