Characterization of ureteral stents by dual-energy computed tomography: Clinical implications

Figure 2 Three-dimensional reconstruction of dual-energy computed tomography images of kidney stones and different types of ureteral stents. Different views of the stent/stone boundary from three-dimensional reconstruction of the dual-energy computed-tomography images. The left and right stents appear red and blue, respectively, while all stones appear blue due to their non-uric-acid composition. The different colors of the stent and stone in the left kidney allow for better stone visualization (arrows) than in the right kidney where both the stent and stone have the same color.
