Determining the chemical composition of renal stones can have a profound effect on clinical management. Dual-energy CT (DECT), including single-source DECT (ssDECT) has been shown to significantly improve renal stone characterization over conventional CT, especially for distinguishing uric acid (UA) from non-UA stones. Distinguishing non-UA subtypes remains problematic, although prior studies have often had to deal with overall low numbers of stones and/or a poor mix of the various non-UA subtypes. The purpose of this study is to investigate utilizing single source dual-energy computed tomography (ssDECT) for the characterization of renal stones.
